From 281628047df688a5d46c223a2076f12bc89ef2f3 Mon Sep 17 00:00:00 2001 From: jogibear9988 Date: Tue, 22 Sep 2026 14:52:28 +0200 Subject: [PATCH 01/34] Add runner filtering, lifecycle stages and transaction modes Introduce additive runner options for tag any/all matching, ordered unversioned profiles, maintenance stages, activation and lock leases. Acquire locks before history refresh and keep version history isolated from auxiliary migrations. Preserve per-migration defaults; add no-transaction and verified-provider whole-session execution with callbacks deferred until commit. Validation: rebuilt solution; SQLite 156 tests and Unit 73 tests passed. Behavioral coverage checks rollback boundaries, post-commit ordering, profile history, tag matching and lock release. Native lock implementations and tooling follow separately. --- src/Migrator.Tests/RunnerFeatureTests.cs | 110 ++++++++ src/Migrator/MigrationExecution.cs | 64 +++-- src/Migrator/MigrationLoader.cs | 341 +++++++++++------------ src/Migrator/Migrator.cs | 95 +++++-- src/Migrator/RunnerOptions.cs | 35 +++ 5 files changed, 414 insertions(+), 231 deletions(-) create mode 100644 src/Migrator.Tests/RunnerFeatureTests.cs create mode 100644 src/Migrator/RunnerOptions.cs diff --git a/src/Migrator.Tests/RunnerFeatureTests.cs b/src/Migrator.Tests/RunnerFeatureTests.cs new file mode 100644 index 00000000..ddd3fb30 --- /dev/null +++ b/src/Migrator.Tests/RunnerFeatureTests.cs @@ -0,0 +1,110 @@ +using System;

Add session-owned SQL Server, PostgreSQL and MySQL/MariaDB locks with timeout and release leases. Package a .NET tool for list, status, validation, migrate, rollback, plan and SQL output. Keep Microsoft dependency injection/options/logging dependencies in an optional package and omit sensitive exception/SQL details in tooling output. Validation: solution rebuilt; Unit 77 and SQLite 159 passed. Added DI activation and CLI argument/list checks, legacy preview opt-in/read-only checks, and live independent-session locking tests for the database CI matrix. --- Migrator.slnx | 8 ++ ...ator.Extensions.DependencyInjection.csproj | 9 ++ .../MigrationLogger.cs | 22 ++++ .../ServiceCollectionExtensions.cs | 31 +++++ src/Migrator.Tests/DatabaseLockTests.cs | 44 +++++++ src/Migrator.Tests/Migrator.Tests.csproj | 2 + src/Migrator.Tests/RunnerFeatureTests.cs | 26 ++++ src/Migrator.Tests/ToolingTests.cs | 49 ++++++++ .../DotNetProjects.Migrator.Tool.csproj | 12 ++ src/Migrator.Tool/Program.cs | 115 ++++++++++++++++++ src/Migrator/DatabaseMigrationLock.cs | 76 ++++++++++++ src/Migrator/MigrationSqlPreview.cs | 62 ++++++++++ src/Migrator/Migrator.cs | 31 ++++- 13 files changed, 486 insertions(+), 1 deletion(-) create mode 100644 src/Migrator.Extensions.DependencyInjection/DotNetProjects.Migrator.Extensions.DependencyInjection.csproj create mode 100644 src/Migrator.Extensions.DependencyInjection/MigrationLogger.cs create mode 100644 src/Migrator.Extensions.DependencyInjection/ServiceCollectionExtensions.cs create mode 100644 src/Migrator.Tests/DatabaseLockTests.cs create mode 100644 src/Migrator.Tests/ToolingTests.cs create mode 100644 src/Migrator.Tool/DotNetProjects.Migrator.Tool.csproj create mode 100644 src/Migrator.Tool/Program.cs create mode 100644 src/Migrator/DatabaseMigrationLock.cs create mode 100644 src/Migrator/MigrationSqlPreview.cs diff --git a/Migrator.slnx b/Migrator.slnx index 4cddff02..cf4bc016 100644 --- a/Migrator.slnx +++ b/Migrator.slnx @@ -13,6 +13,14 @@ + + + + + + + + diff --git a/src/Migrator.Extensions.DependencyInjection/DotNetProjects.Migrator.Extensions.DependencyInjection.csproj b/src/Migrator.Extensions.DependencyInjection/DotNetProjects.Migrator.Extensions.DependencyInjection.csproj new file mode 100644 index 00000000..e8f1027b --- /dev/null +++ b/src/Migrator.Extensions.DependencyInjection/DotNetProjects.Migrator.Extensions.DependencyInjection.csproj @@ -0,0 +1,9 @@ + + net9.09.0.0MPL-1.1Optional dependency injection, options and logging integration for Migrator.NET. + + + + + + + diff --git a/src/Migrator.Extensions.DependencyInjection/MigrationLogger.cs b/src/Migrator.Extensions.DependencyInjection/MigrationLogger.cs new file mode 100644 index 00000000..df2c56d4 --- /dev/null +++ b/src/Migrator.Extensions.DependencyInjection/MigrationLogger.cs @@ -0,0 +1,22 @@ +using System; +using System.Collections.Generic; +using System.Globalization; +using Microsoft.Extensions.Logging; +namespace DotNetProjects.Migrator.Extensions.DependencyInjection; + +/// Logs lifecycle events.

Connected CLI smoke exposed a missing driver-factory registration and is being corrected in the tooling PR before docs completion. --- .gitignore | 39 +- Migrator.slnx | 3 + README.md | 624 ++++---- docs/index.html | 1403 +++++++++-------- docs/migration-framework-comparison.md | 826 +++++----- docs/runner-guide.md | 100 ++ .../FluentQuickStart/FluentQuickStart.csproj | 4 + examples/FluentQuickStart/Program.cs | 30 + 8 files changed, 1588 insertions(+), 1441 deletions(-) create mode 100644 docs/runner-guide.md create mode 100644 examples/FluentQuickStart/FluentQuickStart.csproj create mode 100644 examples/FluentQuickStart/Program.cs diff --git a/.gitignore b/.gitignore index c92f3f9b..02f80861 100644 --- a/.gitignore +++ b/.gitignore @@ -1,19 +1,20 @@ -bin/ -obj/ -*.log -logs/ -_ReSharper*/ -output/ -release/ -*.suo -*.user -*.cache -packages/ - -.vs/ - -/src/GlobalAssemblyInfo.cs -*.gpState - -**/appsettings.Development.json -TestResults/ +bin/ +obj/ +*.log +logs/ +_ReSharper*/ +output/ +release/ +*.suo +*.user +*.cache +packages/ + +.vs/ + +/src/GlobalAssemblyInfo.cs +*.gpState + +**/appsettings.Development.json +TestResults/ +/artifacts/ diff --git a/Migrator.slnx b/Migrator.slnx index cf4bc016..0fad1ce6 100644 --- a/Migrator.slnx +++ b/Migrator.slnx @@ -2,6 +2,9 @@ + + + diff --git a/README.md b/README.md index e8f8b420..529ea7a0 100644 --- a/README.md +++ b/README.md @@ -1,307 +1,317 @@ -# DotNetProjects.Migrator - -**Versioned database migrations in C#, independent of your ORM.** - -[![NuGet version](https://img.shields.io/nuget/v/DotNetProjects.Migrator.svg)](https://www.nuget.org/packages/DotNetProjects.Migrator/) -[![NuGet downloads](https://img.shields.io/nuget/dt/DotNetProjects.Migrator.svg)](https://www.nuget.org/packages/DotNetProjects.Migrator/) -[![Build and tests](https://github.com/dotnetprojects/Migrator.NET/actions/workflows/dotnetpull.yml/badge.svg?branch=master)](https://github.com/dotnetprojects/Migrator.NET/actions/workflows/dotnetpull.yml) -[![GitHub Pages](https://github.com/dotnetprojects/Migrator.NET/actions/workflows/pages.yml/badge.svg?branch=master)](https://github.com/dotnetprojects/Migrator.NET/actions/workflows/pages.yml) -[![Source target: .NET 9](https://img.shields.io/badge/source_target-.NET_9-512BD4)](src/Migrator/DotNetProjects.Migrator.csproj) -[![License: MPL-1.1](https://img.shields.io/badge/license-MPL--1.1-blue.svg)](https://www.mozilla.org/en-US/MPL/1.1/) - -[Homepage & documentation](https://dotnetprojects.github.io/Migrator.NET/) · [NuGet](https://www.nuget.org/packages/DotNetProjects.Migrator/) · [Releases](https://github.com/dotnetprojects/Migrator.NET/releases) · [Issues](https://github.com/dotnetprojects/Migrator.NET/issues) · [Feature comparison](https://dotnetprojects.github.io/Migrator.NET/#compare) - -DotNetProjects.Migrator is a fork of [Migrator.NET](https://github.com/migratordotnet/Migrator.NET).

It does not provide EF-style model-difference scaffolding, a packaged command-line runner, or built-in migration-content checksum validation. - -## Installation and requirements - -```sh -dotnet add package DotNetProjects.Migrator -``` - -Install the ADO.NET driver for your database separately. For the SQLite example below: - -```sh -dotnet add package Microsoft.Data.Sqlite --version 9.0.7 -``` - -The **current source targets `net9.0`**. Check the [NuGet package's framework list](https://www.nuget.org/packages/DotNetProjects.Migrator/#supportedframeworks-body-tab) for the particular release you install; older package releases may target different frameworks. The SQLite driver version above matches the repository's test dependency. - -Building the `.slnx` solution requires an SDK that understands that format, such as .NET SDK 9.0.200 or later. The runtime required by the current source is .NET 9. - -## Quick start - -### 1. Create a migration host - -```sh -dotnet new console -n MigrationDemo -f net9.0 -cd MigrationDemo -dotnet add package DotNetProjects.Migrator -dotnet add package Microsoft.Data.Sqlite --version 9.0.7 -``` - -### 2. Add `CreateUsers.cs` - -Migrations must be public classes implementing the migration contract, decorated with `[Migration(version)]`. Each version must be unique within the set loaded by one runner. - -```csharp -using System.Data; -using DotNetProjects.Migrator.Framework; - -[Migration(1)] -public class CreateUsers : Migration -{ - public override void Up() - { - Database.AddTable("Users", - new Column("Id", DbType.Int32, ColumnProperty.NotNull), - new Column("Name", DbType.String, 255)); - Database.AddPrimaryKey("PK_Users", "Users", "Id"); - } - - public override void Down() - { - Database.RemoveTable("Users"); - } -} -``` - -### 3. Replace `Program.cs` - -```csharp -using DotNetProjects.Migrator; -using DotNetProjects.Migrator.Providers; -using Microsoft.Data.Sqlite; - -using var connection = new SqliteConnection("Data Source=app.db"); -connection.Open(); - -using var provider = ProviderFactory.Create( - ProviderTypes.SQLite, connection, defaultSchema: null); - -var migrator = new Migrator( - provider, typeof(CreateUsers).Assembly, trace: false); - -if (migrator.LastAppliedMigrationVersion is long applied - && applied > migrator.AssemblyLastMigrationVersion) -{ - throw new InvalidOperationException( - "Database version is newer than this application."); -} - -migrator.MigrateToLastVersion(); -``` - -### 4. Run it - -```sh -dotnet run -``` - -This creates a local SQLite database containing `Users` and the migration history table. Running the application again skips version `1` because it has already been recorded. Add a new class with `[Migration(2)]` for the next change. - -The example supplies an **open** `IDbConnection`. The caller owns that connection and disposes it after the provider. If you use the connection-string overload instead, the selected provider must be able to resolve the appropriate ADO.NET factory. - -## Migration versions and rollback - -Use increasing numeric versions, or the attribute's date-based constructor: - -```csharp -[Migration(2026, 9, 22, 12, 0, 0)] -``` - -Keep applied migration classes in source control. Change the schema with a new migration instead of editing an already applied one: history records the version, not a checksum of the migration's content. - -| API | Purpose | -| ------------------------------ | -------------------------------------------------------------------------------- | -| `MigrateToLastVersion()` | Apply through the latest version in the loaded migration set. | -| `MigrateTo(version)` | Move to a chosen version, invoking `Up()` or `Down()` as required. | -| `AppliedMigrations` | List the versions recorded for the provider's scope. | -| `LastAppliedMigrationVersion` | Highest applied version, or `null` when none are applied. | -| `AssemblyLastMigrationVersion` | Highest version in the loaded migration set. | -| `SchemaInfoTableName` | Customize the history table name before accessing history or running migrations. | - -With the runner above, `migrator.MigrateTo(0)` reverses all applied migrations in its set. In this example that drops `Users`, including its data. A `Down()` implementation is a reverse schema operation, not a backup restore. - -Migration execution starts a transaction for each migration and attempts rollback on failure. Actual atomicity depends on the database, driver and operation; some databases implicitly commit DDL. `AfterUp()` and `AfterDown()` run **after commit**, so a failure in those hooks cannot undo the committed migration. - -For deployment, run a dedicated migration host before the application needs the new schema. Coordinate it so competing instances do not migrate the same database concurrently. Review and test both directions against your actual database engine. - -## Multiple modules and migration scopes - -The default history table is `SchemaInfo`, with version, scope and timestamp information. The default scope is `"default"`. You can use separate scopes for modules sharing a database. - -Within a host with an open `connection`, select the module's migration types explicitly: - -```csharp -using var billingProvider = ProviderFactory.Create( - ProviderTypes.SQLite, - connection, - defaultSchema: null, - scope: "billing"); - -var billingMigrator = new Migrator( - billingProvider, - false, - typeof(Billing001), - typeof(Billing002)); - -billingMigrator.MigrateToLastVersion(); -``` - -`Billing001` and `Billing002` represent your own public migration classes. Alternatively, give the runner an assembly that contains only that module's migrations. - -Important details: - -- In the upgrade source, explicit scopes filter discovery; unscoped migrations inherit the runner scope. A scope partitions history, not database objects. -- Leave `MigrationAttribute.Scope` unset to inherit the provider scope; set it to select a migration for one specific scope. -- Duplicate versions are checked within the effective scope. Duplicate versions in distinct explicit scopes are independent. -- Scopes do not isolate tables or data. Module migrations still need compatible table names and coordinated schema ownership. - -See [ProviderFactory](src/Migrator/ProviderFactory.cs), [MigrationLoader](src/Migrator/MigrationLoader.cs) and [history implementation](src/Migrator/Providers/TransformationProvider.cs). - -## Schema and data operations - -Inside a migration, `Database` implements [`ITransformationProvider`](src/Migrator/Framework/ITransformationProvider.cs). It includes: - -| Area | Examples | -| ------------------ | ------------------------------------------------------------------------------------- | -| Tables and columns | `AddTable`, `RemoveTable`, `RenameTable`, `AddColumn`, `ChangeColumn`, `RemoveColumn` | -| Keys and indexes | `AddPrimaryKey`, `AddForeignKey`, `AddIndex` and corresponding removal operations | -| Schema inspection | `TableExists`, `ColumnExists`, `GetTables`, `GetColumns` | -| Data and SQL | `Insert`, `Update`, `Delete`, `ExecuteNonQuery`, `ExecuteQuery`, `ExecuteScalar` | - -For example, a new migration can add a column: - -```csharp -public override void Up() -{ - Database.AddColumn("Users", new Column("Email", DbType.String, 320)); -} - -public override void Down() -{ - Database.RemoveColumn("Users", "Email"); -} -``` - -Provider implementations determine which operations are available and how they map to SQL. Use `Database.ExecuteNonQuery(...)` for custom SQL and keep dialect-specific statements explicit. The source also includes a [schema builder API](src/Migrator/Framework/SchemaBuilder/SchemaBuilder.cs). - -## Database providers - -The [provider factory](src/Migrator/ProviderFactory.cs) contains these database families: - -| Database | `ProviderTypes` value(s) | -| ------------ | ---------------------------- | -| SQL Server | `SqlServer`, `SqlServer2005` | -| PostgreSQL | `PostgreSQL`, `PostgreSQL82` | -| SQLite | `SQLite`, `MonoSQLite` | -| MySQL | `Mysql` | -| MariaDB | `MariaDB` | -| Oracle | `Oracle`, `MsOracle` | -| IBM Db2 | `IBM_DB2` | -| IBM Informix | `IBM_Informix` | -| Firebird | `Firebird` | -| Ingres | `Ingres` | -| Sybase | `Sybase` | - -This is an inventory of dialects present in source, **not a guarantee that every server version, driver or operation is supported**. Some entries are legacy variants. Verify the combination you deploy against the [provider implementations](src/Migrator/Providers/Impl) and [provider tests](src/Migrator.Tests/Providers). - -## Comparison with other .NET frameworks - -Reviewed **22 September 2026**. Migrator's column describes this repository; the alternatives summarize their official documentation. These are workflow differences, not performance benchmarks or a ranking. - -| Capability | Migrator.NET (this fork) | FluentMigrator | EF Core | DbUp | Evolve | -| ---------------------------- | --------------------------------- | -------------------------------------------- | ------------------------------------ | -------------------------- | --------------------------------- | -| Authoring | Handwritten C# transformation API | Handwritten C# fluent DSL | C# scaffolded from model differences | SQL or C# scripts | Versioned SQL files | -| ORM-independent workflow | Yes | Yes | Uses EF model / DbContext | Yes | Yes | -| Model-difference scaffolding | No built-in generator | Hand-authored | Yes, with model snapshots | Hand-authored | Hand-authored | -| Downgrade applied migrations | Authored `Down()` | `Down()`; supported auto-reverse expressions | Generated/editable `Down()` | Custom undo or forward fix | Forward fix; no Down command | -| Separate histories | Scope + selected assembly/types | Custom version table + filtering | Contexts + custom history table | Journals + script filters | Metadata table/schema + locations | -| Execution | Library / custom host | Library + CLI | CLI, scripts, bundles, runtime | Library / custom host | Library, .NET tool, CLI | -| Recurring work | Custom code | Maintenance migrations / profiles | Seeding APIs (EF 9+) | `RunAlways` scripts | Checksum-based repeatable SQL | - -All five can execute raw SQL. Transaction support depends on database capabilities: Migrator starts one per migration; DbUp makes transactions opt-in; the others have configurable transaction behavior. Reversing a completed migration is different from rolling back a failed transaction. Evolve's checksum-based repeatables also differ from always-run scripts or lifecycle hooks. - -- Choose **Migrator** for direct C# schema operations, scoped history and integration with your own host. -- Consider **FluentMigrator** for its fluent authoring API, packaged runners, tags and profiles. -- Consider **EF Core migrations** when your EF model drives the schema and you want scaffolding and deployment artifacts. -- Consider **DbUp** for a SQL-oriented runner composed in .NET, or **Evolve** for convention-based SQL with checksum validation and repeatables. - -Sources: [Migrator runner](src/Migrator/Migrator.cs), [FluentMigrator quick start](https://fluentmigrator.github.io/intro/quick-start.html) and [configuration](https://fluentmigrator.github.io/intro/configuration.html), [EF Core migrations](https://learn.microsoft.com/en-us/ef/core/managing-schemas/migrations/) and [deployment](https://learn.microsoft.com/en-us/ef/core/managing-schemas/migrations/applying), [DbUp documentation](https://dbup.readthedocs.io/en/latest/) and [script types](https://dbup.readthedocs.io/en/latest/more-info/script-types/), [Evolve concepts](https://evolve-db.netlify.app/concepts/).

SMALL API. EXPLICIT CONTROL.

-

- Your schema has a history.
Keep it in the repository. -

-
-
- 01 / AUTHOR -

C# without an ORM dependency

-

- Define tables, columns, indexes and constraints through a - transformation API. Use raw SQL when a change needs - database-specific behavior. -

-
-
- 02 / VERSION -

Move forward. Step back.

-

- Number your migrations, implement Up() and - Down(), and migrate to a chosen version. Applied - migrations are recorded in the database. -

-
-
- 03 / ORGANIZE -

Separate histories by scope

-

- Keep module version histories in one database using named scopes. - Select each module’s migration assembly or types when you create - its runner. -

-
-
-
-
-
-
-
-

QUICK START

-

From code to schema.

-
-

- A minimal SQLite example.
Use a .NET 9 console project for - the current source. -

-
-
-
- 1 -

Install the packages

-

- Add Migrator and an ADO.NET driver. This example passes an open - connection directly to the provider. -

- View package versions on NuGet ↗ -
-
-
- Terminal -
- 
dotnet new console -n MigrationDemo -f net9.0
-cd MigrationDemo
-dotnet add package DotNetProjects.Migrator
-dotnet add package Microsoft.Data.Sqlite --version 9.0.7
-
-
-
-
- 2 -

Describe the change

-

- Add a public migration class. Each version must be unique within - the migration set loaded by a runner. -

-

- Down() is your explicit reverse operation; dropping - a table also removes its data. -

-
-
-
- CreateUsers.cs -
- 
using System.Data;
-using DotNetProjects.Migrator.Framework;
-
-[Migration(1)]
-public class CreateUsers : Migration
-{
-    public override void Up()
-    {
-        Database.AddTable("Users",
-            new Column("Id", DbType.Int32,
-                ColumnProperty.NotNull),
-            new Column("Name", DbType.String, 255));
-        Database.AddPrimaryKey("PK_Users", "Users", "Id");
-    }
-
-    public override void Down()
-    {
-        Database.RemoveTable("Users");
-    }
-}
-
-
-
-
- 3 -

Run pending migrations

-

- Replace Program.cs with this code, then run - dotnet run. The runner discovers the migration in - your assembly and records it under the default scope. -

-

- Subsequent runs skip applied versions. Use - MigrateTo(version) to target an earlier or later - version. -

-
-
-
- Program.cs -
- 
using DotNetProjects.Migrator;
-using DotNetProjects.Migrator.Providers;
-using Microsoft.Data.Sqlite;
-
-using var connection = new SqliteConnection("Data Source=app.db");
-connection.Open();
-
-using var provider = ProviderFactory.Create(
-    ProviderTypes.SQLite, connection, defaultSchema: null);
-
-var migrator = new Migrator(
-    provider, typeof(CreateUsers).Assembly, trace: false);
-
-if (migrator.LastAppliedMigrationVersion is long applied
-    && applied > migrator.AssemblyLastMigrationVersion)
-{
-    throw new InvalidOperationException(
-        "Database version is newer than this application.");

[Provider list][d-databases]. | SQL dialect translation. | -| Evolve | Database integrations. [Requirements][e-requirements]. | SQL translation or identical transactions. | - -A migration can compile yet require a table copy, lose an unsupported schema detail or fail on existing data. Compare the exact operation and data shape, not just database names. - -## SQLite emulation comparison - -### What emulation means - -SQLite has native table rename, column rename, add-column and (on sufficiently recent engines, subject to restrictions) drop-column operations. SQLite 3.53.0 added native `ALTER COLUMN … SET/DROP NOT NULL`; it still does not provide general type/default alteration or `ALTER TABLE ADD/DROP CONSTRAINT`. More complex changes require a replacement table, copying rows and rebuilding dependent objects. Native capabilities evolve independently of the .NET driver package. [SQLite ALTER TABLE reference][sqlite-alter]. - -Migrator reads the **live schema** into `SQLiteTableInfo`, modifies that representation and calls `RecreateTable`. It creates `Temp`, copies mapped columns with `INSERT … SELECT`, drops the original, renames the replacement and recreates represented indexes. This works without an ORM model, but depends on what its schema reader can represent. [Implementation][m-sqlite], [schema model][m-sqlite-model]. - -### Automatic operation matrix - -**R** = built-in rebuild; **N** = native SQL path, subject to engine restrictions; **U** = unique-index substitution; **Manual** = author the change/rebuild yourself; **Manual** also covers a generated statement that the engine does not support. Rows describe **changes to an existing table**, not constraints declared when creating it. - -The combined SQL-runner column applies **individually to DbUp and Evolve**: both execute supplied SQL rather than diffing/rebuilding the schema. grate and RoundhousE follow the same distinction. Manual does not mean the engine cannot perform the operation. - -Evidence: [EF Core SQLite operation table][ef-sqlite], [FluentMigrator SQLite generator][f-sqlite-generator], [inherited SQL templates][f-generic-generator] and [processor][f-sqlite-processor], [DbUp scripts][d-usage], [Evolve concepts][e-concepts].

Migrator still rebuilds for nullability changes; FluentMigrator still rejects its general alter-column expression even when a newer engine can execute a hand-authored NOT NULL alteration. - -EF Core rebuilds rely on model-represented artifacts; the docs identify failures for artifacts outside that model. EF 9+ uses a SQLite lock table with abandoned-lock recovery considerations. These are separate from rebuild support. [SQLite limitations][ef-sqlite]. - -FluentMigrator supports inline FKs during table creation. Its reviewed generator directs callers to manual reconstruction for later FK changes; `LOOSE` mode skips unsupported expressions rather than emulating them. Unique-index substitution does not imply that an existing table-level UNIQUE constraint can be dropped as an index. [Generator][f-sqlite-generator]. - -### Migrator's emulated operations, precisely - -Methods refer to the pinned [SQLite provider][m-sqlite].

A packaged CLI and dedicated SQL-preview/export workflow. -2. Validation of edits to already applied migration content. -3. Cross-process migration locking and explicit failure recovery. -4. Repeatable migrations distinct from execution hooks. -5. Stronger SQLite preservation of triggers, generated columns, table options and complex indexes. -6. Clearer bulk-removal semantics and FK-state restoration after exceptions. -7. Continued operation-level provider documentation and live test coverage. - -## Validation and maintenance - -Reviewed in a separate Git worktree based on `ab3aa9f`. No migration implementation files or parallel-refactoring checkout were changed. - -The existing SQLite category was executed on Windows: - -```sh -dotnet test src/Migrator.Tests/Migrator.Tests.csproj --configuration Release --filter "TestCategory=SQLite" -``` - -**139 passed, 1 skipped, 0 failed.** The skipped test is `ChangeColumn_RemoveDefaultValue_Success`, documented by [issue #139](https://github.com/dotnetprojects/Migrator.NET/issues/139). Existing compiler warnings were present. This validates existing scenarios, not the complete preservation matrix. Competitors were reviewed through documentation/source, **not executed in a comparative test harness**. - -When updating: - -- Pin the new source revision and recheck SQLite rebuilds after refactoring. -- Verify competitor provider versions before promoting “Check” to a compatibility promise. -- Keep native SQL, automatic emulation and author-written workarounds distinct. -- Review

database migration frameworks: detailed feature comparison + +**Reviewed: 22 September 2026.** This is a capability comparison, not a benchmark or an overall ranking. + +The main matrices cover **DotNetProjects.Migrator, FluentMigrator, EF Core migrations, DbUp and Evolve**—all five frameworks on the homepage. Additional sections cover **EF6, grate and RoundhousE**, with a short boundary comparison for **Flyway and Liquibase**. This is a defined shortlist, not a claim to catalogue every migration package ever published. + +Migrator findings are pinned to upgrade-stack commit [`874cb88`][m-revision].

FluentMigrator's SQLite implementation is pinned to [`2e0acdb`][f-sqlite-generator].

SQLite 3.53.0 added native `ALTER COLUMN … SET/DROP NOT NULL`; it still does not provide general type/default alteration or `ALTER TABLE ADD/DROP CONSTRAINT`. More complex changes require a replacement table, copying rows and rebuilding dependent objects. Native capabilities evolve independently of the .NET driver package. [SQLite ALTER TABLE reference][sqlite-alter]. + +Migrator reads the **live schema** into `SQLiteTableInfo`, modifies that representation and calls `RecreateTable`. It creates `
Temp`, copies mapped columns with `INSERT … SELECT`, drops the original, renames the replacement and recreates represented indexes. This works without an ORM model, but depends on what its schema reader can represent. [Implementation][m-sqlite], [schema model][m-sqlite-model]. + +### Automatic operation matrix + +**R** = built-in rebuild; **N** = native SQL path, subject to engine restrictions; **U** = unique-index substitution; **Manual** = author the change/rebuild yourself; **Manual** also covers a generated statement that the engine does not support. Rows describe **changes to an existing table**, not constraints declared when creating it. + +The combined SQL-runner column applies **individually to DbUp and Evolve**: both execute supplied SQL rather than diffing/rebuilding the schema. grate and RoundhousE follow the same distinction. Manual does not mean the engine cannot perform the operation. + +Evidence: [EF Core SQLite operation table][ef-sqlite], [FluentMigrator SQLite generator][f-sqlite-generator], [inherited SQL templates][f-generic-generator] and [processor][f-sqlite-processor], [DbUp scripts][d-usage], [Evolve concepts][e-concepts].

Migrator still rebuilds for nullability changes; FluentMigrator still rejects its general alter-column expression even when a newer engine can execute a hand-authored NOT NULL alteration. + +EF Core rebuilds rely on model-represented artifacts; the docs identify failures for artifacts outside that model. EF 9+ uses a SQLite lock table with abandoned-lock recovery considerations. These are separate from rebuild support. [SQLite limitations][ef-sqlite]. + +FluentMigrator supports inline FKs during table creation. Its reviewed generator directs callers to manual reconstruction for later FK changes; `LOOSE` mode skips unsupported expressions rather than emulating them. Unique-index substitution does not imply that an existing table-level UNIQUE constraint can be dropped as an index.

describe the source upgrade under review in PRs #173, #174, #175 and #177. They are not a statement about the currently released NuGet packages. Build the repository to try them; no package publication is part of this change. + +## Fluent quick start + +The [compiled quick-start project](../examples/FluentQuickStart/Program.cs) executes preview, migration and automatic reversal against SQLite: + +```sh +dotnet run --project examples/FluentQuickStart +``` + +```csharp +[Migration(1, Scope = "demo"), Tags("core")] +public class CreateUsers : AutoReversingMigration +{ + public override void BuildUp(MigrationBuilder migration) + { + migration.Create.Table("Users") + .WithColumn("Id").AsInt32().PrimaryKey() + .WithColumn("Name").AsString(255).NotNullable(); + } +} +``` + +Use `DotNetProjects.Migrator`, `.Framework` and `.Framework.Fluent`. A table definition is completed before execution. Existing imperative `Migration.Up/Down` classes keep working. `FluentMigration` supports authored `BuildDown`; `AutoReversingMigration` reverses supported create/rename operations in reverse order. Destructive changes, data, SQL and callbacks need explicit reverse operations. Automatic reversal never restores deleted data. + +The builder has `Create`, `Alter`, `Delete`, `Rename`, `Insert`, `Update`, `Execute` and `Administration`. Schema inspection is exposed through `FluentMigration.Schema`, and the provider through `Context`. History and transaction methods remain explicit context operations. Some administrative/data-copy operations use provider callbacks and cannot generate SQL previews. + +## Runner options + +`runner.Options` supports: + +| Option | Semantics | +| --- | --- | +| `Tags` / `TagMatch` | Ordinal names; explicit `Any` or `All`. No filter selects all versioned migrations. Filtered applied versions remain applied on downgrade. | +| `Profiles` | Explicit names of `[Profile("name")]` classes. Run after versioned migrations without recording versions; run again when selected again. | +| `TransactionMode` | `PerMigration` by default; `None` or `WholeSession` available. | +| `Activator` | Optional constructor activation delegate. | +| `Lock` / `LockTimeout` | Optional `IMigrationLock` lease; acquire before reading history and release on completion/failure. | + +Unscoped migrations inherit the provider scope; explicitly scoped migrations run only in that scope. Discovery, duplicate validation and history reads use the effective scope. Scopes separate history, not tables. Legacy custom providers can adopt the additive `IMigrationHistory` interface for read-only planning and effective-scope selection. + +Maintenance classes use `[Maintenance(MaintenanceStage.BeforeRun)]`, `BeforeMigration`, `AfterMigration` or `AfterRun`. Profiles and maintenance accept `Order` and `Scope`. Ordering uses `Order` then ordinal full type name. Hooks stop on failure; later hooks are not cleanup guarantees. Connection/transaction restoration and lock release do not depend on hooks running. Profiles and maintenance use `Up`; they do not acquire version records. + +## Transactions and locks + +`PerMigration` commits each successful migration. `None` leaves transaction behavior to the provider/operations. `WholeSession` is accepted for SQLite, PostgreSQL and SQL Server dialects; history-table initialization occurs before that transaction. Other dialects fail explicitly because transactional DDL has not been verified. Arbitrary imperative SQL can still violate transaction assumptions; database administration and implicit-commit statements require separate runs. + +`AfterUp`/`AfterDown` run after commit. In whole-session mode they are deferred until the complete session commits. Their failure reports an error after durable changes; it cannot undo a successful commit. Caller-owned connections remain caller-owned. + +`new DatabaseMigrationLock()` uses SQL Server application locks, PostgreSQL advisory locks or MySQL/MariaDB named locks. Locks are session-owned, keyed by database/history table/scope, and remain held across migration commits. Do not switch databases, replace/close the connection or manipulate the native lock inside a migration. Unsupported providers, including SQLite, reject this lock implementation. Supply a custom `IMigrationLock` where another coordination mechanism is required. MySQL named locks coordinate one server, not an entire distributed cluster. + +## Planning and SQL preview + +`runner.Plan(target)` and `DryRun` inspect history without creating/upgrading it and do not invoke migration bodies, callbacks, transactions or SQLite PRAGMA changes. Custom providers must implement `IMigrationHistory` for these paths. + +`runner.PreviewSql(target, providerType)` connects for history/schema reads. `MigrationSqlPreview.Generate(providerType, migrations)` can generate SQL offline. Earlier structured operations update a planned schema so later operations can refer to newly created/renamed tables. SQL preview currently supports a subset: basic tables/columns, supported renames, simple indexes, inserts and raw SQL. Unsupported alterations, constraints, filters, callbacks and schema dependencies fail explicitly. Output is operation SQL, not an idempotent history-managed deployment bundle. + +Imperative bodies require `allowLegacyBodies: true`. Provider calls are captured through a rejecting proxy: direct connections, commands and unsupported reads/callbacks are blocked. **Arbitrary C# cannot be sandboxed**: constructors, fluent authoring and opted-in imperative bodies can still access files, networks or external state. Use trusted migration code. `InitializeOnce` and post-commit callbacks do not run during preview. + +## CLI from source + +```sh +dotnet pack src/Migrator.Tool -o artifacts/packages +dotnet tool install DotNetProjects.Migrator.Tool --add-source artifacts/packages --tool-path artifacts/tools +``` + +Set `MIGRATOR_CONNECTION` in your environment; the tool does not print its value.

Offline SQL assumes empty history and currently rejects profiles/maintenance. `validate` validates version planning, not arbitrary migration-body behavior. The packaged drivers cover SQLite, SQL Server, PostgreSQL, MySQL/MariaDB, Oracle and Firebird. Other library providers need a custom host. + +Exit codes: `0` success, `1` execution/load failure, `2` invalid arguments, `3` unsupported operation/provider, `4` lock timeout. SQL output may contain migration data; exception and provider trace details are omitted from CLI diagnostics. + +## Optional DI and logging + +The source package `DotNetProjects.Migrator.Extensions.DependencyInjection` provides `services.AddMigrator(providerFactory, migrationAssembly, configureOptions)`. Resolve `Migrator` inside a service scope; migration constructors use that scope's services. Options are scoped snapshots. Provider disposal follows the DI scope. Microsoft logging records lifecycle events while omitting SQL text and raw exception messages; the core retains its lightweight logger API. + +## Validation + +Build before using the test scripts (they intentionally use `--no-build`): + +```sh +dotnet build Migrator.slnx +pwsh .github/scripts/test.ps1 -Database Unit +pwsh .github/scripts/test.ps1 -Database SQLite +``` + +See [live database tests](live-database-tests.md) for the full matrix.

These changes are under review and **are not a released NuGet feature claim**. See the [runner and fluent guide](docs/runner-guide.md) and [detailed framework comparison](docs/migration-framework-comparison.md). EF-style model scaffolding and migration-content checksums remain outside the implementation. - -## Installation and requirements - -```sh -dotnet add package DotNetProjects.Migrator -``` - -Install the ADO.NET driver for your database separately. For the SQLite example below: - -```sh -dotnet add package Microsoft.Data.Sqlite --version 9.0.7 -``` - -The **current source targets `net9.0`**. Check the [NuGet package's framework list](https://www.nuget.org/packages/DotNetProjects.Migrator/#supportedframeworks-body-tab) for the particular release you install; older package releases may target different frameworks. The SQLite driver version above matches the repository's test dependency. - -Building the `.slnx` solution requires an SDK that understands that format, such as .NET SDK 9.0.200 or later. The runtime required by the current source is .NET 9. - -## Quick start - -### 1. Create a migration host - -```sh -dotnet new console -n MigrationDemo -f net9.0 -cd MigrationDemo -dotnet add package DotNetProjects.Migrator -dotnet add package Microsoft.Data.Sqlite --version 9.0.7 -``` - -### 2. Add `CreateUsers.cs` - -Migrations must be public classes implementing the migration contract, decorated with `[Migration(version)]`. Each version must be unique within the set loaded by one runner. - -```csharp -using System.Data; -using DotNetProjects.Migrator.Framework; - -[Migration(1)] -public class CreateUsers : Migration -{ - public override void Up() - { - Database.AddTable("Users", - new Column("Id", DbType.Int32, ColumnProperty.NotNull), - new Column("Name", DbType.String, 255)); - Database.AddPrimaryKey("PK_Users", "Users", "Id"); - } - - public override void Down() - { - Database.RemoveTable("Users"); - } -} -``` - -### 3. Replace `Program.cs` - -```csharp -using DotNetProjects.Migrator; -using DotNetProjects.Migrator.Providers; -using Microsoft.Data.Sqlite; - -using var connection = new SqliteConnection("Data Source=app.db"); -connection.Open(); - -using var provider = ProviderFactory.Create( - ProviderTypes.SQLite, connection, defaultSchema: null); - -var migrator = new Migrator( - provider, typeof(CreateUsers).Assembly, trace: false); - -if (migrator.LastAppliedMigrationVersion is long applied - && applied > migrator.AssemblyLastMigrationVersion) -{ - throw new InvalidOperationException( - "Database version is newer than this application."); -} - -migrator.MigrateToLastVersion(); -``` - -### 4. Run it - -```sh -dotnet run -``` - -This creates a local SQLite database containing `Users` and the migration history table. Running the application again skips version `1` because it has already been recorded. Add a new class with `[Migration(2)]` for the next change. - -The example supplies an **open** `IDbConnection`. The caller owns that connection and disposes it after the provider. If you use the connection-string overload instead, the selected provider must be able to resolve the appropriate ADO.NET factory. - -## Migration versions and rollback - -Use increasing numeric versions, or the attribute's date-based constructor: - -```csharp -[Migration(2026, 9, 22, 12, 0, 0)] -``` - -Keep applied migration classes in source control. Change the schema with a new migration instead of editing an already applied one: history records the version, not a checksum of the migration's content. - -| API | Purpose | -| ------------------------------ | -------------------------------------------------------------------------------- | -| `MigrateToLastVersion()` | Apply through the latest version in the loaded migration set. | -| `MigrateTo(version)` | Move to a chosen version, invoking `Up()` or `Down()` as required. | -| `AppliedMigrations` | List the versions recorded for the provider's scope. | -| `LastAppliedMigrationVersion` | Highest applied version, or `null` when none are applied. | -| `AssemblyLastMigrationVersion` | Highest version in the loaded migration set. | -| `SchemaInfoTableName` | Customize the history table name before accessing history or running migrations. | - -With the runner above, `migrator.MigrateTo(0)` reverses all applied migrations in its set. In this example that drops `Users`, including its data. A `Down()` implementation is a reverse schema operation, not a backup restore. - -Migration execution starts a transaction for each migration and attempts rollback on failure. Actual atomicity depends on the database, driver and operation; some databases implicitly commit DDL. `AfterUp()` and `AfterDown()` run **after commit**, so a failure in those hooks cannot undo the committed migration. - -For deployment, run a dedicated migration host before the application needs the new schema. Coordinate it so competing instances do not migrate the same database concurrently. Review and test both directions against your actual database engine. - -## Multiple modules and migration scopes - -The default history table is `SchemaInfo`, with version, scope and timestamp information. The default scope is `"default"`. You can use separate scopes for modules sharing a database. - -Within a host with an open `connection`, select the module's migration types explicitly: - -```csharp -using var billingProvider = ProviderFactory.Create( - ProviderTypes.SQLite, - connection, - defaultSchema: null, - scope: "billing"); - -var billingMigrator = new Migrator( - billingProvider, - false, - typeof(Billing001), - typeof(Billing002)); - -billingMigrator.MigrateToLastVersion(); -``` - -`Billing001` and `Billing002` represent your own public migration classes. Alternatively, give the runner an assembly that contains only that module's migrations. - -Important details: - -- In the upgrade source, explicit scopes filter discovery; unscoped migrations inherit the runner scope. A scope partitions history, not database objects. -- Leave `MigrationAttribute.Scope` unset to inherit the provider scope; set it to select a migration for one specific scope. -- Duplicate versions are checked within the effective scope. Duplicate versions in distinct explicit scopes are independent. -- Scopes do not isolate tables or data. Module migrations still need compatible table names and coordinated schema ownership. - -See [ProviderFactory](src/Migrator/ProviderFactory.cs), [MigrationLoader](src/Migrator/MigrationLoader.cs) and [history implementation](src/Migrator/Providers/TransformationProvider.cs). - -## Fluent API and deployment tooling - -Run the [compiled fluent example](examples/FluentQuickStart/Program.cs): - -```sh -dotnet run --project examples/FluentQuickStart -``` - -The example creates a complete table definition, previews it without changing history, runs a whole-session migration, then verifies automatic reversal. The [runner guide](docs/runner-guide.md) covers CLI commands, tags/profiles, maintenance, transactions, optional DI/logging, locks and preview limitations. Build the source packages locally to try the new tooling; no NuGet publication accompanies these PRs. - -## Schema and data operations - -Inside a migration, `Database` implements [`ITransformationProvider`](src/Migrator/Framework/ITransformationProvider.cs). It includes: - -| Area | Examples | -| ------------------ | ------------------------------------------------------------------------------------- | -| Tables and columns | `AddTable`, `RemoveTable`, `RenameTable`, `AddColumn`, `ChangeColumn`, `RemoveColumn` | -| Keys and indexes | `AddPrimaryKey`, `AddForeignKey`, `AddIndex` and corresponding removal operations | -| Schema inspection | `TableExists`, `ColumnExists`, `GetTables`, `GetColumns` | -| Data and SQL | `Insert`, `Update`, `Delete`, `ExecuteNonQuery`, `ExecuteQuery`, `ExecuteScalar` | - -For example, a new migration can add a column: - -```csharp -public override void Up() -{ - Database.AddColumn("Users", new Column("Email", DbType.String, 320)); -} - -public override void Down() -{ - Database.RemoveColumn("Users", "Email"); -} -``` - -Provider implementations determine which operations are available and how they map to SQL. Use `Database.ExecuteNonQuery(...)` for custom SQL and keep dialect-specific statements explicit. The source also includes a [schema builder API](src/Migrator/Framework/SchemaBuilder/SchemaBuilder.cs). - -## Database providers - -The [provider factory](src/Migrator/ProviderFactory.cs) contains these database families: - -| Database | `ProviderTypes` value(s) | -| ------------ | ---------------------------- | -| SQL Server | `SqlServer`, `SqlServer2005` | -| PostgreSQL | `PostgreSQL`, `PostgreSQL82` | -| SQLite | `SQLite`, `MonoSQLite` | -| MySQL | `Mysql` | -| MariaDB | `MariaDB` | -| Oracle | `Oracle`, `MsOracle` | -| IBM Db2 | `IBM_DB2` | -| IBM Informix | `IBM_Informix` | -| Firebird | `Firebird` | -| Ingres | `Ingres` | -| Sybase | `Sybase` | - -This is an inventory of dialects present in source, **not a guarantee that every server version, driver or operation is supported**.

Write each schema change as a numbered C# class, commit it alongside your application, and use the runner to bring a database to the required version. The database records which migrations have already been applied. + +## Contents + +- [Why use it?](#why-use-it) +- [Installation and requirements](#installation-and-requirements) +- [Quick start](#quick-start) +- [Migration versions and rollback](#migration-versions-and-rollback) +- [Multiple modules and migration scopes](#multiple-modules-and-migration-scopes) +- [Schema and data operations](#schema-and-data-operations) +- [Database providers](#database-providers) +- [Comparison with other .NET frameworks](#comparison-with-other-net-frameworks) +- [Building and testing](#building-and-testing) +- [Documentation and GitHub Pages](#documentation-and-github-pages) +- [Contributing and project history](#contributing-and-project-history) +- [License](#license) + +## Why use it? + +- **Explicit C# migrations.** Define forward and reverse changes with `Up()` and `Down()`; review them like application code. +- **No ORM dependency.** Use it alongside EF, Dapper, another data layer, or plain ADO.NET. +- **Database transformation API.** Work with tables, columns, keys, indexes and data, with raw SQL available for provider-specific operations. +- **Version tracking.** Apply pending migrations or target a specific version using database-backed history. +- **Scoped histories.** Track multiple modules in one database when each runner is given the appropriate migration set. +- **Bring your database driver.** The library does not directly reference database-driver packages; supply an ADO.NET connection or configure the driver factory. +- **SQLite schema handling.** This fork includes schema inspection and table-recreation logic for operations SQLite cannot perform directly. + +The source upgrade adds a structured fluent API, runner filtering/lifecycle options, SQL-preview subset, native locking, a CLI project and optional Microsoft DI/logging integration. These changes are under review and **are not a released NuGet feature claim**. See the [runner and fluent guide](docs/runner-guide.md) and [detailed framework comparison](docs/migration-framework-comparison.md). EF-style model scaffolding and migration-content checksums remain outside the implementation. + +## Installation and requirements + +```sh +dotnet add package DotNetProjects.Migrator +``` + +Install the ADO.NET driver for your database separately. For the SQLite example below: + +```sh +dotnet add package Microsoft.Data.Sqlite --version 9.0.7 +``` + +The **current source targets `net9.0`**. Check the [NuGet package's framework list](https://www.nuget.org/packages/DotNetProjects.Migrator/#supportedframeworks-body-tab) for the particular release you install; older package releases may target different frameworks. The SQLite driver version above matches the repository's test dependency. + +Building the `.slnx` solution requires an SDK that understands that format, such as .NET SDK 9.0.200 or later. The runtime required by the current source is .NET 9. + +## Quick start + +### 1. Create a migration host + +```sh +dotnet new console -n MigrationDemo -f net9.0 +cd MigrationDemo +dotnet add package DotNetProjects.Migrator +dotnet add package Microsoft.Data.Sqlite --version 9.0.7 +``` + +### 2. Add `CreateUsers.cs` + +Migrations must be public classes implementing the migration contract, decorated with `[Migration(version)]`. Each version must be unique within the set loaded by one runner. + +```csharp +using System.Data; +using DotNetProjects.Migrator.Framework; + +[Migration(1)] +public class CreateUsers : Migration +{ + public override void Up() + { + Database.AddTable("Users", + new Column("Id", DbType.Int32, ColumnProperty.NotNull), + new Column("Name", DbType.String, 255)); + Database.AddPrimaryKey("PK_Users", "Users", "Id"); + } + + public override void Down() + { + Database.RemoveTable("Users"); + } +} +``` + +### 3. Replace `Program.cs` + +```csharp +using DotNetProjects.Migrator; +using DotNetProjects.Migrator.Providers; +using Microsoft.Data.Sqlite; + +using var connection = new SqliteConnection("Data Source=app.db"); +connection.Open(); + +using var provider = ProviderFactory.Create( + ProviderTypes.SQLite, connection, defaultSchema: null); + +var migrator = new Migrator( + provider, typeof(CreateUsers).Assembly, trace: false); + +if (migrator.LastAppliedMigrationVersion is long applied + && applied > migrator.AssemblyLastMigrationVersion) +{ + throw new InvalidOperationException( + "Database version is newer than this application."); +} + +migrator.MigrateToLastVersion(); +``` + +### 4. Run it + +```sh +dotnet run +``` + +This creates a local SQLite database containing `Users` and the migration history table. Running the application again skips version `1` because it has already been recorded. Add a new class with `[Migration(2)]` for the next change. + +The example supplies an **open** `IDbConnection`. The caller owns that connection and disposes it after the provider. If you use the connection-string overload instead, the selected provider must be able to resolve the appropriate ADO.NET factory. + +## Migration versions and rollback + +Use increasing numeric versions, or the attribute's date-based constructor: + +```csharp +[Migration(2026, 9, 22, 12, 0, 0)] +``` + +Keep applied migration classes in source control. Change the schema with a new migration instead of editing an already applied one: history records the version, not a checksum of the migration's content. + +| API | Purpose | +| ------------------------------ | -------------------------------------------------------------------------------- | +| `MigrateToLastVersion()` | Apply through the latest version in the loaded migration set. | +| `MigrateTo(version)` | Move to a chosen version, invoking `Up()` or `Down()` as required. | +| `AppliedMigrations` | List the versions recorded for the provider's scope. | +| `LastAppliedMigrationVersion` | Highest applied version, or `null` when none are applied. | +| `AssemblyLastMigrationVersion` | Highest version in the loaded migration set. | +| `SchemaInfoTableName` | Customize the history table name before accessing history or running migrations. | + +With the runner above, `migrator.MigrateTo(0)` reverses all applied migrations in its set. In this example that drops `Users`, including its data. A `Down()` implementation is a reverse schema operation, not a backup restore. + +Migration execution starts a transaction for each migration and attempts rollback on failure. Actual atomicity depends on the database, driver and operation; some databases implicitly commit DDL. `AfterUp()` and `AfterDown()` run **after commit**, so a failure in those hooks cannot undo the committed migration. + +For deployment, run a dedicated migration host before the application needs the new schema. Coordinate it so competing instances do not migrate the same database concurrently. Review and test both directions against your actual database engine. + +## Multiple modules and migration scopes + +The default history table is `SchemaInfo`, with version, scope and timestamp information. The default scope is `"default"`. You can use separate scopes for modules sharing a database. + +Within a host with an open `connection`, select the module's migration types explicitly: + +```csharp +using var billingProvider = ProviderFactory.Create( + ProviderTypes.SQLite, + connection, + defaultSchema: null, + scope: "billing"); + +var billingMigrator = new Migrator( + billingProvider, + false, + typeof(Billing001), + typeof(Billing002)); + +billingMigrator.MigrateToLastVersion(); +``` + +`Billing001` and `Billing002` represent your own public migration classes. Alternatively, give the runner an assembly that contains only that module's migrations. + +Important details: + +- In the upgrade source, explicit scopes filter discovery; unscoped migrations inherit the runner scope. A scope partitions history, not database objects. +- Leave `MigrationAttribute.Scope` unset to inherit the provider scope; set it to select a migration for one specific scope. +- Duplicate versions are checked within the effective scope. Duplicate versions in distinct explicit scopes are independent. +- Scopes do not isolate tables or data. Module migrations still need compatible table names and coordinated schema ownership. + +See [ProviderFactory](src/Migrator/ProviderFactory.cs), [MigrationLoader](src/Migrator/MigrationLoader.cs) and [history implementation](src/Migrator/Providers/TransformationProvider.cs). + +## Fluent API and deployment tooling + +Run the [compiled fluent example](examples/FluentQuickStart/Program.cs): + +```sh +dotnet run --project examples/FluentQuickStart +``` + +The example creates a complete table definition, previews it without changing history, runs a whole-session migration, then verifies automatic reversal. The [runner guide](docs/runner-guide.md) covers CLI commands, tags/profiles, maintenance, transactions, optional DI/logging, locks and preview limitations. Build the source packages locally to try the new tooling; no NuGet publication accompanies these PRs. + +## Schema and data operations + +Inside a migration, `Database` implements [`ITransformationProvider`](src/Migrator/Framework/ITransformationProvider.cs). It includes: + +| Area | Examples | +| ------------------ | ------------------------------------------------------------------------------------- | +| Tables and columns | `AddTable`, `RemoveTable`, `RenameTable`, `AddColumn`, `ChangeColumn`, `RemoveColumn` | +| Keys and indexes | `AddPrimaryKey`, `AddForeignKey`, `AddIndex` and corresponding removal operations | +| Schema inspection | `TableExists`, `ColumnExists`, `GetTables`, `GetColumns` | +| Data and SQL | `Insert`, `Update`, `Delete`, `ExecuteNonQuery`, `ExecuteQuery`, `ExecuteScalar` | + +For example, a new migration can add a column: + +```csharp +public override void Up() +{ + Database.AddColumn("Users", new Column("Email", DbType.String, 320)); +} + +public override void Down() +{ + Database.RemoveColumn("Users", "Email"); +} +``` + +Provider implementations determine which operations are available and how they map to SQL. Use `Database.ExecuteNonQuery(...)` for custom SQL and keep dialect-specific statements explicit. The source also includes a [schema builder API](src/Migrator/Framework/SchemaBuilder/SchemaBuilder.cs). + +## Database providers + +The [provider factory](src/Migrator/ProviderFactory.cs) contains these database families: + +| Database | `ProviderTypes` value(s) | +| ------------ | ---------------------------- | +| SQL Server | `SqlServer`, `SqlServer2005` | +| PostgreSQL | `PostgreSQL`, `PostgreSQL82` | +| SQLite | `SQLite`, `MonoSQLite` | +| MySQL | `Mysql` | +| MariaDB | `MariaDB` | +| Oracle | `Oracle`, `MsOracle` | +| IBM Db2 | `IBM_DB2` | +| IBM Informix | `IBM_Informix` | +| Firebird | `Firebird` | +| Ingres | `Ingres` | +| Sybase | `Sybase` | + +This is an inventory of dialects present in source, **not a guarantee that every server version, driver or operation is supported**.

SMALL API. EXPLICIT CONTROL.

-

- Your schema has a history.
Keep it in the repository. -

-
-
- 01 / AUTHOR -

C# without an ORM dependency

-

- Define tables, columns, indexes and constraints through a - transformation API. Use raw SQL when a change needs - database-specific behavior. -

-
-
- 02 / VERSION -

Move forward. Step back.

-

- Number your migrations, implement Up() and - Down(), and migrate to a chosen version. Applied - migrations are recorded in the database. -

-
-
- 03 / ORGANIZE -

Separate histories by scope

-

- Keep module version histories in one database using named scopes. - Select each module’s migration assembly or types when you create - its runner. -

-
-
-
-
-
-
-
-

QUICK START

-

From code to schema.

-
-

- A minimal SQLite example.
Use a .NET 9 console project for - the current source. -

-
-
-
- 1 -

Install the packages

-

- Add Migrator and an ADO.NET driver. This example passes an open - connection directly to the provider. -

- View package versions on NuGet ↗ -
-
-
- Terminal -
- 
dotnet new console -n MigrationDemo -f net9.0
-cd MigrationDemo
-dotnet add package DotNetProjects.Migrator
-dotnet add package Microsoft.Data.Sqlite --version 9.0.7
-
-
-
-
- 2 -

Describe the change

-

- Add a public migration class. Each version must be unique within - the migration set loaded by a runner. -

-

- Down() is your explicit reverse operation; dropping - a table also removes its data. -

-
-
-
- CreateUsers.cs -
- 
using System.Data;
-using DotNetProjects.Migrator.Framework;
-
-[Migration(1)]
-public class CreateUsers : Migration
-{
-    public override void Up()
-    {
-        Database.AddTable("Users",
-            new Column("Id", DbType.Int32,
-                ColumnProperty.NotNull),
-            new Column("Name", DbType.String, 255));
-        Database.AddPrimaryKey("PK_Users", "Users", "Id");
-    }
-
-    public override void Down()
-    {
-        Database.RemoveTable("Users");
-    }
-}
-
-
-
-
- 3 -

Run pending migrations

-

- Replace Program.cs with this code, then run - dotnet run. The runner discovers the migration in - your assembly and records it under the default scope. -

-

- Subsequent runs skip applied versions. Use - MigrateTo(version) to target an earlier or later - version. -

-
-
-
- Program.cs -
- 
using DotNetProjects.Migrator;
-using DotNetProjects.Migrator.Providers;
-using Microsoft.Data.Sqlite;
-
-using var connection = new SqliteConnection("Data Source=app.db");
-connection.Open();
-
-using var provider = ProviderFactory.Create(
-    ProviderTypes.SQLite, connection, defaultSchema: null);
-
-var migrator = new Migrator(
-    provider, typeof(CreateUsers).Assembly, trace: false);
-
-if (migrator.LastAppliedMigrationVersion is long applied
-    && applied > migrator.AssemblyLastMigrationVersion)
-{
-    throw new InvalidOperationException(
-        "Database version is newer than this application.");

SMALL API. EXPLICIT CONTROL.

+

+ Your schema has a history.
Keep it in the repository. +

+
+
+ 01 / AUTHOR +

C# without an ORM dependency

+

+ Define tables, columns, indexes and constraints through a + transformation API. Use raw SQL when a change needs + database-specific behavior. +

+
+
+ 02 / VERSION +

Move forward. Step back.

+

+ Number your migrations, implement Up() and + Down(), and migrate to a chosen version. Applied + migrations are recorded in the database. +

+
+
+ 03 / ORGANIZE +

Separate histories by scope

+

+ Keep module version histories in one database using named scopes. + Select each module’s migration assembly or types when you create + its runner. +

+
+
+
+
+
+
+
+

QUICK START

+

From code to schema.

+
+

+ A minimal SQLite example.
Use a .NET 9 console project for + the current source. +

+
+
+
+ 1 +

Install the packages

+

+ Add Migrator and an ADO.NET driver. This example passes an open + connection directly to the provider. +

+ View package versions on NuGet ↗ +
+
+
+ Terminal +
+ 
dotnet new console -n MigrationDemo -f net9.0
+cd MigrationDemo
+dotnet add package DotNetProjects.Migrator
+dotnet add package Microsoft.Data.Sqlite --version 9.0.7
+
+
+
+
+ 2 +

Describe the change

+

+ Add a public migration class. Each version must be unique within + the migration set loaded by a runner. +

+

+ Down() is your explicit reverse operation; dropping + a table also removes its data. +

+
+
+
+ CreateUsers.cs +
+ 
using System.Data;
+using DotNetProjects.Migrator.Framework;
+
+[Migration(1)]
+public class CreateUsers : Migration
+{
+    public override void Up()
+    {
+        Database.AddTable("Users",
+            new Column("Id", DbType.Int32,
+                ColumnProperty.NotNull),
+            new Column("Name", DbType.String, 255));
+        Database.AddPrimaryKey("PK_Users", "Users", "Id");
+    }
+
+    public override void Down()
+    {
+        Database.RemoveTable("Users");
+    }
+}
+
+
+
+
+ 3 +

Run pending migrations

+

+ Replace Program.cs with this code, then run + dotnet run. The runner discovers the migration in + your assembly and records it under the default scope. +

+

+ Subsequent runs skip applied versions. Use + MigrateTo(version) to target an earlier or later + version. +

+
+
+
+ Program.cs +
+ 
using DotNetProjects.Migrator;
+using DotNetProjects.Migrator.Providers;
+using Microsoft.Data.Sqlite;
+
+using var connection = new SqliteConnection("Data Source=app.db");
+connection.Open();
+
+using var provider = ProviderFactory.Create(
+    ProviderTypes.SQLite, connection, defaultSchema: null);
+
+var migrator = new Migrator(
+    provider, typeof(CreateUsers).Assembly, trace: false);
+
+if (migrator.LastAppliedMigrationVersion is long applied
+    && applied > migrator.AssemblyLastMigrationVersion)
+{
+    throw new InvalidOperationException(
+        "Database version is newer than this application.");
+}
+
+migrator.MigrateToLastVersion();
+
+
+ +
+
+
+
+
+

DATABASE PROVIDERS

+

One API. Multiple dialects.

+
+

+ Supply your ADO.NET driver.
Migrator supplies the schema + operations. +

+
+
+

  • SQL Server
    • +
  • PostgreSQL
    • +
  • SQLite
    • +
  • MySQL
    • +
  • MariaDB

  • IBM Informix
    • +
  • Firebird
    • +
  • Ingres
    • +
  • Sybase
    • +
+
+
+

+ This is an implementation inventory, not a certification of every + server or driver version. Schema operations and transactional DDL vary + by provider. Check the + provider factory + and + provider tests + for your database. +

[Provider list][d-databases]. | SQL dialect translation. | -| Evolve | Database integrations. [Requirements][e-requirements]. | SQL translation or identical transactions. | - -A migration can compile yet require a table copy, lose an unsupported schema detail or fail on existing data. Compare the exact operation and data shape, not just database names. - -## SQLite emulation comparison - -### What emulation means - -SQLite has native table rename, column rename, add-column and (on sufficiently recent engines, subject to restrictions) drop-column operations. SQLite 3.53.0 added native `ALTER COLUMN … SET/DROP NOT NULL`; it still does not provide general type/default alteration or `ALTER TABLE ADD/DROP CONSTRAINT`. More complex changes require a replacement table, copying rows and rebuilding dependent objects. Native capabilities evolve independently of the .NET driver package. [SQLite ALTER TABLE reference][sqlite-alter]. - -Migrator reads the **live schema** into `SQLiteTableInfo`, modifies that representation and calls `RecreateTable`. It creates `Temp`, copies mapped columns with `INSERT … SELECT`, drops the original, renames the replacement and recreates represented indexes. This works without an ORM model, but depends on what its schema reader can represent. [Implementation][m-sqlite], [schema model][m-sqlite-model]. - -### Automatic operation matrix - -**R** = built-in rebuild; **N** = native SQL path, subject to engine restrictions; **U** = unique-index substitution; **Manual** = author the change/rebuild yourself; **Manual** also covers a generated statement that the engine does not support. Rows describe **changes to an existing table**, not constraints declared when creating it. - -The combined SQL-runner column applies **individually to DbUp and Evolve**: both execute supplied SQL rather than diffing/rebuilding the schema. grate and RoundhousE follow the same distinction. Manual does not mean the engine cannot perform the operation. - -Evidence: [EF Core SQLite operation table][ef-sqlite], [FluentMigrator SQLite generator][f-sqlite-generator], [inherited SQL templates][f-generic-generator] and [processor][f-sqlite-processor], [DbUp scripts][d-usage], [Evolve concepts][e-concepts].

Migrator still rebuilds for nullability changes; FluentMigrator still rejects its general alter-column expression even when a newer engine can execute a hand-authored NOT NULL alteration. - -EF Core rebuilds rely on model-represented artifacts; the docs identify failures for artifacts outside that model. EF 9+ uses a SQLite lock table with abandoned-lock recovery considerations. These are separate from rebuild support. [SQLite limitations][ef-sqlite]. - -FluentMigrator supports inline FKs during table creation. Its reviewed generator directs callers to manual reconstruction for later FK changes; `LOOSE` mode skips unsupported expressions rather than emulating them. Unique-index substitution does not imply that an existing table-level UNIQUE constraint can be dropped as an index. [Generator][f-sqlite-generator]. - -### Migrator's emulated operations, precisely - -Methods refer to the pinned [SQLite provider][m-sqlite].

[Tests][t-add-column]. | -| `ChangeColumn` | Replaces the entire matching `Column` definition; rebuilds. | Specify properties to retain. Type affinity during copying is not arbitrary data conversion. [Tests][t-change-column]. | -| `RemoveColumnDefaultValue` | Clears parsed default; rebuilds. Generic default-removal regression is enabled and passes. | Dedicated and generic default-removal regressions run; provider CI is required for changes. [Tests][t-sqlite-general]. | -| `RemoveColumn` | Removes column/mapping and matching single-column indexes/uniques/FKs; rebuilds affected tables. | Rejects detected CHECK references and composite dependencies until adjusted. Can remove inbound single-column FKs from other tables. [Tests][t-remove-column]. | -| `RenameColumn` | Native on SQLite 3.26+; reconstruction fallback for older engines. | Native rename delegates dependency rewriting to SQLite; reconstruction is not an arbitrary SQL-expression rewriter.

Broader structured SQL-preview coverage, provider-specific batch scripts and CLI deployment validation. The source CLI and preview subset already exist. -2. Validation of edits to already applied migration content. -3. More native lock backends and recovery/concurrency validation; three database families now have opt-in locks. -4. Repeatable migrations distinct from execution hooks. -5. SQLite native drop-column selection, generated columns, table options, sequence state and complex-index preservation beyond the currently guarded subset. -6. Complete imperative/fluent operation coverage and ownership-aware default/uniqueness cleanup. -7. Continued operation-level provider documentation and live test coverage. - -## Validation and maintenance - -The original master baseline (`ab3aa9f`) had 139 passing SQLite tests and one skipped default-removal test. At upgrade source `874cb88`, a rebuilt solution passed **83 unit tests and 160 SQLite tests, with no skips**. Provider PR #174 passed all eleven database/unit jobs and the coverage gate in [run 35729926918](https://github.com/dotnetprojects/Migrator.NET/actions/runs/35729926918). New native-lock tests in #177 require their own live CI verification. - -This is not a complete implementation of the upgrade plan: SQL preview supports a structured subset; offline CLI rejects profiles/maintenance; batch scripts, operation inventory, several provider ownership/metadata fixes and broader deployment regressions remain work in progress. Competitors were reviewed through documentation/source, **not executed in a comparative harness**. - -When updating: - -- Pin the new source revision and recheck SQLite rebuilds after refactoring. --

SQLite 3.53.0 added native `ALTER COLUMN … SET/DROP NOT NULL`; it still does not provide general type/default alteration or `ALTER TABLE ADD/DROP CONSTRAINT`. More complex changes require a replacement table, copying rows and rebuilding dependent objects. Native capabilities evolve independently of the .NET driver package. [SQLite ALTER TABLE reference][sqlite-alter]. + +Migrator reads the **live schema** into `SQLiteTableInfo`, modifies that representation and calls `RecreateTable`. It creates `
Temp`, copies mapped columns with `INSERT … SELECT`, drops the original, renames the replacement and recreates represented indexes. This works without an ORM model, but depends on what its schema reader can represent. [Implementation][m-sqlite], [schema model][m-sqlite-model]. + +### Automatic operation matrix + +**R** = built-in rebuild; **N** = native SQL path, subject to engine restrictions; **U** = unique-index substitution; **Manual** = author the change/rebuild yourself; **Manual** also covers a generated statement that the engine does not support. Rows describe **changes to an existing table**, not constraints declared when creating it. + +The combined SQL-runner column applies **individually to DbUp and Evolve**: both execute supplied SQL rather than diffing/rebuilding the schema. grate and RoundhousE follow the same distinction. Manual does not mean the engine cannot perform the operation. + +Evidence: [EF Core SQLite operation table][ef-sqlite], [FluentMigrator SQLite generator][f-sqlite-generator], [inherited SQL templates][f-generic-generator] and [processor][f-sqlite-processor], [DbUp scripts][d-usage], [Evolve concepts][e-concepts].

Migrator still rebuilds for nullability changes; FluentMigrator still rejects its general alter-column expression even when a newer engine can execute a hand-authored NOT NULL alteration. + +EF Core rebuilds rely on model-represented artifacts; the docs identify failures for artifacts outside that model. EF 9+ uses a SQLite lock table with abandoned-lock recovery considerations. These are separate from rebuild support. [SQLite limitations][ef-sqlite]. + +FluentMigrator supports inline FKs during table creation. Its reviewed generator directs callers to manual reconstruction for later FK changes; `LOOSE` mode skips unsupported expressions rather than emulating them. Unique-index substitution does not imply that an existing table-level UNIQUE constraint can be dropped as an index.

Continued operation-level provider documentation and live test coverage. + +## Validation and maintenance + +The master baseline (`b7ae95c`) passed 139 SQLite tests with one skipped default-removal test. At upgrade source `8d8818e`, a rebuilt solution passed **89 unit tests and 173 SQLite tests, with no skips**.

MySQL named locks coordinate one server, not an entire distributed cluster. - -## Planning and SQL preview - -`runner.Plan(target)` and `DryRun` inspect history without creating/upgrading it and do not invoke migration bodies, callbacks, transactions or SQLite PRAGMA changes. Custom providers must implement `IMigrationHistory` for these paths. - -`runner.PreviewSql(target, providerType)` connects for history/schema reads. `MigrationSqlPreview.Generate(providerType, migrations)` can generate SQL offline. Earlier structured operations update a planned schema so later operations can refer to newly created/renamed tables. SQL preview currently supports a subset: basic tables/columns, supported renames, simple indexes, inserts and raw SQL. Unsupported alterations, constraints, filters, callbacks and schema dependencies fail explicitly. Output is operation SQL, not an idempotent history-managed deployment bundle. - -Imperative bodies require `allowLegacyBodies: true`. Provider calls are captured through a rejecting proxy: direct connections, commands and unsupported reads/callbacks are blocked. **Arbitrary C# cannot be sandboxed**: constructors, fluent authoring and opted-in imperative bodies can still access files, networks or external state. Use trusted migration code. `InitializeOnce` and post-commit callbacks do not run during preview. - -## CLI from source - -```sh -dotnet pack src/Migrator.Tool -o artifacts/packages -dotnet tool install DotNetProjects.Migrator.Tool --add-source artifacts/packages --tool-path artifacts/tools -``` - -Set `MIGRATOR_CONNECTION` in your environment; the tool does not print its value.

Offline SQL assumes empty history and currently rejects profiles/maintenance. `validate` validates version planning, not arbitrary migration-body behavior. The packaged drivers cover SQLite, SQL Server, PostgreSQL, MySQL/MariaDB, Oracle and Firebird. Other library providers need a custom host. - -Exit codes: `0` success, `1` execution/load failure, `2` invalid arguments, `3` unsupported operation/provider, `4` lock timeout. SQL output may contain migration data; exception and provider trace details are omitted from CLI diagnostics. - -## Optional DI and logging - -The source package `DotNetProjects.Migrator.Extensions.DependencyInjection` provides `services.AddMigrator(providerFactory, migrationAssembly, configureOptions)`. Resolve `Migrator` inside a service scope; migration constructors use that scope's services. Options are scoped snapshots. Provider disposal follows the DI scope. Microsoft logging records lifecycle events while omitting SQL text and raw exception messages; the core retains its lightweight logger API. - -## Validation - -Build before using the test scripts (they intentionally use `--no-build`): - -```sh -dotnet build Migrator.slnx -pwsh .github/scripts/test.ps1 -Database Unit -pwsh .github/scripts/test.ps1 -Database SQLite -``` - -See [live database tests](live-database-tests.md) for the full matrix.

Supply a custom `IMigrationLock` where another coordination mechanism is required. MySQL named locks coordinate one server, not an entire distributed cluster. + +## Planning and SQL preview + +`runner.Plan(target)` and `DryRun` inspect history without creating/upgrading it and do not invoke migration bodies, callbacks, transactions or SQLite PRAGMA changes. Custom providers must implement `IMigrationHistory` for these paths. + +`runner.PreviewSql(target, providerType)` connects for history/schema reads. `MigrationSqlPreview.Generate(providerType, migrations)` can generate SQL offline. Earlier structured operations update a planned schema so later operations can refer to newly created/renamed tables. SQL preview currently supports a subset: basic tables/columns, supported renames, simple indexes, inserts and raw SQL. Unsupported alterations, constraints, filters, callbacks and schema dependencies fail explicitly. Output is operation SQL, not an idempotent history-managed deployment bundle. + +Imperative bodies require `allowLegacyBodies: true`. Provider calls are captured through a rejecting proxy: direct connections, commands and unsupported reads/callbacks are blocked. **Arbitrary C# cannot be sandboxed**: constructors, fluent authoring and opted-in imperative bodies can still access files, networks or external state. Use trusted migration code. Migrations overriding `InitializeOnce` are rejected before their body runs, because skipping initialization could produce misleading SQL. Post-commit callbacks do not run during preview. Raw SQL invalidates planned schema knowledge, so later structured schema dependencies fail explicitly. + +## CLI from source + +```sh +dotnet pack src/Migrator.Tool -o artifacts/packages +dotnet tool install DotNetProjects.Migrator.Tool --add-source artifacts/packages --tool-path artifacts/tools +``` + +Set `MIGRATOR_CONNECTION` in your environment; the tool does not print its value. Common commands: + +```sh +migrator list --assembly MyMigrations.dll --provider SQLite +migrator status --assembly MyMigrations.dll --provider SQLite +migrator validate --assembly MyMigrations.dll --provider SQLite +migrator plan --assembly MyMigrations.dll --provider SQLite --target 10 +migrator sql --assembly MyMigrations.dll --provider SQLite --output migration.sql +migrator sql --assembly MyMigrations.dll --provider SQLite --offline --output migration.sql +migrator migrate --assembly MyMigrations.dll --provider SQLite --scope billing --transaction WholeSession +migrator rollback --assembly MyMigrations.dll --provider SQLite --target 0 +``` + +Use `--connection-env NAME`, `--schema`, `--tags a,b`, `--tag-match Any|All`, `--profiles a,b`, `--timeout SECONDS`, `--lock` and `--lock-timeout SECONDS` where applicable. `rollback` requires an explicit lower target and rejects any plan containing upward steps. Target validation runs after acquiring the configured lock and refreshing history. Offline SQL assumes empty history and currently rejects profiles/maintenance. `validate` validates version planning, not arbitrary migration-body behavior. The packaged drivers cover SQLite, SQL Server, PostgreSQL, MySQL/MariaDB, Oracle and Firebird. Other library providers need a custom host. + +Exit codes: `0` success, `1` execution/load failure, `2` invalid arguments, `3` unsupported operation/provider, `4` lock timeout. SQL output may contain migration data; exception and provider trace details are omitted from CLI diagnostics. + +## Optional DI and logging + +The source package `DotNetProjects.Migrator.Extensions.DependencyInjection` provides `services.AddMigrator(providerFactory, migrationAssembly, configureOptions)`. Resolve `Migrator` inside a service scope; migration constructors use that scope's services. Options are scoped snapshots. Provider disposal follows the DI scope. Microsoft logging records lifecycle events while omitting SQL text and raw exception messages; the core retains its lightweight logger API. + +## Validation + +Build before using the test scripts (they intentionally use `--no-build`): + +```sh +dotnet build Migrator.slnx +pwsh .github/scripts/test.ps1 -Database Unit +pwsh .github/scripts/test.ps1 -Database SQLite +``` + +See [live database tests](live-database-tests.md) for the full matrix. Provider-specific changes need live provider evidence. Check PR CI and review threads after every push; reply with implementation/test evidence and resolve fixed findings. Keep commits descriptive and merge the PR stack in dependency order only after review. From 508218ab3f53199aa45a383c09ebc598e49896b2 Mon Sep 17 00:00:00 2001 From: jogibear9988 Date: Tue, 22 Sep 2026 16:10:30 +0200 Subject: [PATCH 13/34] Document script semantics, ownership cleanup and the complete issue inventory Record all 81 issue identities with verified closures, pending fixes and explicitly incomplete historical reproduction work. Update the source-pinned comparison and runner guide for SQL Server GO scripts, Oracle caller-owned legacy sequences and SQL Server uniqueness ownership. Record the observed Windows native-library path limitation. Validation: build, Unit 96 passed, SQLite 176 passed; compiled quick start passes. Locally packed tool 9.0.0-upgrade-review.1 generated offline SQL, then migrated/status-checked/rolled back SQLite from a short installation path.

Broader behavioral parity tests beyond the [fluent method-family inventory](fluent-operation-coverage.md), and provider coverage for explicit adoption of historical uniqueness objects without ownership markers. 7. Continued operation-level provider documentation and live test coverage. ## Validation and maintenance -The master baseline (`b7ae95c`) passed 139 SQLite tests with one skipped default-removal test. At the earlier upgrade source `8d8818e`, a rebuilt solution passed **89 unit tests and 173 SQLite tests, with no skips**. The newly pinned revision passed **96 unit tests and 176 SQLite tests** locally. The packed/installed tool passed offline SQL, migration, status and rollback smoke checks. It must still be checked against its own live PR run.

The pinned upgrade revision passed **93 unit tests and 184 SQLite tests, with no skips**, after rebuilding the solution. Test counts reflect replacement of assertion-free tests with behavioral checks. The packed/installed tool previously passed offline SQL, migration, status and rollback smoke checks.

This is not a complete implementation of the upgrade plan: SQL preview supports a structured subset; offline CLI rejects profiles/maintenance; full client-script dialects, remaining metadata/legacy ownership cases and broader deployment regressions remain work in progress. SQL Server GO splitting and explicit Oracle legacy sequence cleanup are implemented. See the [81-issue inventory](issue-audit.md) for verified closures and incomplete audit items.

Columns expose independent nullability, identity, unsigned and explicit collation attributes; table keys and unique/check constraints remain named ordered objects. Consolidate authoring on MigrationBuilder and update examples and the operation coverage inventory. Render column clauses through ColumnAttribute dialect mappings. Stop implicit unique-constraint ownership and removal during ChangeColumn, remove SQL Server collation inference, and change Oracle columns in place. SQLite preserves named and unnamed constraints independently of column attributes, reports physical column order, distinguishes AUTOINCREMENT, and preserves table uniqueness when removing indexes. Add structured constraint readers for Db2, Firebird, Informix and Sybase for live matrix validation. Document the source/API breaks and concrete replacements in the 12.1-to-13 guide. Convert legacy flag tests to schema and persisted-data assertions. Local validation: complete solution builds; 87 unit and 192 SQLite tests pass with no skips.

Add native Informix and ASE readers, preserving composite column pairing and keeping unique indexes separate from declared constraints in metadata. Render Informix inline constraint names using its suffix syntax. Treat Oracle DEFAULT NULL as absence of a value, including string columns. Make tests request unique constraints explicitly after ChangeColumn and remove unrelated unsigned attributes from PostgreSQL identity/index fixtures. Use the same pure SQLite CREATE TABLE renderer for imperative execution and structured preview, including named identity keys, uniqueness and collation. Verify generated SQL against SQLite rather than only asserting its text. Validation: solution build; 87 unit tests and 193 SQLite tests pass locally. The new composite-FK catalog regression runs in six live database matrix jobs. This follow-up addresses failures found in PR #181 run 35756650482; live database verification is required on the new head before the PR is ready. --- .../Providers/Live/LiveDatabaseTests.cs | 18 +++ .../Live/LiveMetadataRegressionTests.cs | 3 +- ...ionProvider_PrimaryKeyWithIdentityTests.cs | 2 +- ...ansformationProvider_ReservedWordsTests.cs | 2 +- ...SQLiteTransformationProvider_GetUniques.cs | 6 +- src/Migrator.Tests/SchemaConstraintTests.cs | 17 +++ src/Migrator/Framework/Fluent/Operations.cs | 10 +- .../Providers/ForeignKeyMetadataReader.cs | 93 +++++++++++++ .../Impl/Informix/InformixDialect.cs | 17 +++ .../InformixTransformationProvider.cs | 15 ++ .../Oracle/OracleTransformationProvider.cs | 2 +- .../Providers/Impl/SQLite/SQLiteTableSql.cs | 128 ++++++++++++++++++ .../SQLite/SQLiteTransformationProvider.cs | 111 +-------------- .../Sybase/SybaseTransformationProvider.cs | 25 ++++ .../Providers/TransformationProvider.cs | 74 +--------- 15 files changed, 334 insertions(+), 189 deletions(-) create mode 100644 src/Migrator/Providers/ForeignKeyMetadataReader.cs create mode 100644 src/Migrator/Providers/Impl/SQLite/SQLiteTableSql.cs diff --git a/src/Migrator.Tests/Providers/Live/LiveDatabaseTests.cs b/src/Migrator.Tests/Providers/Live/LiveDatabaseTests.cs index aba5077d..c9a99d6e 100644 --- a/src/Migrator.Tests/Providers/Live/LiveDatabaseTests.cs +++ b/src/Migrator.Tests/Providers/Live/LiveDatabaseTests.cs @@ -33,6 +33,24 @@ internal void RunRegression(Action action) finally { TearDown();

SQLite renders the required expression parentheses and preserves typed expressions, escaped literals, GUIDs and numeric defaults through catalog reads and table reconstruction. Replace the new string-only collation property with a typed Collation definition. Both imperative columns and fluent builders accept the same semantic presets or named provider escape hatch. Resolve supported comparisons in SQL Server, MySQL, MariaDB, PostgreSQL and SQLite dialects; reject unmapped requests and non-text columns before execution. Never substitute SQLite ASCII folding for Unicode case-insensitivity. Document expression trust, function availability, provider/version requirements, language and ordering limits, PostgreSQL ICU configuration and metadata changes in the 12.1-to-13 migration guide. Account for MySQL/MariaDB catalog equivalence between unique indexes and unique constraints in the composite-FK regression. Validation: solution build; 87 unit and 195 SQLite tests pass locally. Added live case/accent comparison tests for MySQL/MariaDB and SQL Server, plus SQL Server NEWID defaults in imperative and fluent creation. Live jobs must pass on this head. --- docs/migration-guide-12.1-to-13.md | 53 +++++++++++++++ .../Providers/Live/LiveDatabaseTests.cs | 5 +- .../Live/LiveMetadataRegressionTests.cs | 19 ++++++ ...erverTransformationProviderGenericTests.cs | 19 ++++++ src/Migrator.Tests/SchemaConstraintTests.cs | 51 +++++++++++++++ src/Migrator/Framework/Collation.cs | 28 ++++++++ src/Migrator/Framework/Column.cs | 2 +- .../Framework/Fluent/MigrationBuilder.cs | 4 +- src/Migrator/Framework/IColumn.cs | 2 +- src/Migrator/Framework/IDialect.cs | 1 + src/Migrator/Framework/RawSql.cs | 19 ++++++ src/Migrator/Providers/CatalogDefaultValue.cs | 13 ++-- .../Providers/ColumnPropertiesMapper.cs | 6 +- src/Migrator/Providers/Dialect.cs | 11 ++++ .../Providers/Impl/Mysql/MariaDBDialect.cs | 6 ++ .../Providers/Impl/Mysql/MysqlDialect.cs | 6 ++ .../Impl/PostgreSQL/PostgreSQLDialect.cs | 6 ++ .../Providers/Impl/SQLite/SQLiteDialect.cs | 7 ++ .../SQLite/SQLiteTransformationProvider.cs | 64 +------------------ .../Impl/SqlServer/SqlServerDialect.cs | 6 ++ 20 files changed, 254 insertions(+), 74 deletions(-) create mode 100644 src/Migrator/Framework/Collation.cs create mode 100644 src/Migrator/Framework/RawSql.cs diff --git a/docs/migration-guide-12.1-to-13.md b/docs/migration-guide-12.1-to-13.md index caf8e090..39d89783 100644 --- a/docs/migration-guide-12.1-to-13.md +++ b/docs/migration-guide-12.1-to-13.md @@ -143,3 +143,56 @@ Reviewed 2026-09-22: ## Additional v13 candidates Evaluate typed schema-qualified identifiers, explicit literal versus SQL-expression defaults, ordered constraint metadata, deterministic constraint naming, SQLite constraint parsing without regular-expression guesses, typed provider capabilities, and removal of obsolete duplicate authoring APIs.

Validation: rebuilt solution; all 197 SQLite tests pass, including new behavioral regressions for concatenated defaults and comment-adjacent named keys through a rebuild, persisted values and duplicate-key enforcement. --- src/Migrator.Tests/SchemaConstraintTests.cs | 24 +++++++++++++++++++ src/Migrator/Providers/CatalogDefaultValue.cs | 2 +- .../Impl/SQLite/SQLiteConstraintParser.cs | 3 ++- 3 files changed, 27 insertions(+), 2 deletions(-) diff --git a/src/Migrator.Tests/SchemaConstraintTests.cs b/src/Migrator.Tests/SchemaConstraintTests.cs index ac63d5e0..e512a9a7 100644 --- a/src/Migrator.Tests/SchemaConstraintTests.cs +++ b/src/Migrator.Tests/SchemaConstraintTests.cs @@ -173,6 +173,30 @@ public void SemanticCollationDoesNotSilentlyDowngradeUnicodeToAscii() Assert.That(Convert.ToInt32(provider.ExecuteScalar("SELECT COUNT(*) FROM AsciiNames")), Is.EqualTo(3)); } + [Test] + public void MetadataDoesNotConfuseConcatenatedExpressionsWithStringLiterals() + { + using var provider = ProviderFactory.Create(ProviderTypes.SQLite, "Data Source=:memory:", null); + provider.AddTable("ConcatDefault", new Column("Id", DbType.Int32), + new Column("Value", DbType.String, 30) { DefaultValue = RawSql.Insert("'A' || 'B'") }); + Assert.That(provider.GetColumns("ConcatDefault").Single(c => c.Name == "Value").DefaultValue, Is.TypeOf()); + provider.ChangeColumn("ConcatDefault", new Column("Id", DbType.Int64)); + provider.ExecuteNonQuery("INSERT INTO ConcatDefault (Id) VALUES (1)"); + Assert.That(provider.ExecuteScalar("SELECT Value FROM ConcatDefault"), Is.EqualTo("AB")); + } + + [Test] + public void ConstraintTokenizerRecognizesCommentsAdjacentToKeywords() + { + using var provider = ProviderFactory.Create(ProviderTypes.SQLite, "Data Source=:memory:", null); + provider.ExecuteNonQuery("CREATE TABLE CommentedKey (Id INTEGER NOT NULL, Label TEXT, CONSTRAINT/*name*/pk PRIMARY/*kind*/KEY(Id))"); + Assert.That(provider.GetTableConstraints("CommentedKey").OfType().Single().Name, Is.EqualTo("pk")); + provider.ChangeColumn("CommentedKey", new Column("Label", DbType.String, 40)); + Assert.That(provider.GetTableConstraints("CommentedKey").OfType().Single().Name, Is.EqualTo("pk")); + provider.Insert("CommentedKey", ["Id"], [1]); + Assert.Catch(() => provider.Insert("CommentedKey", ["Id"], [1])); + } + [Test] public void InvalidKeyDefinitionsFailBeforeCreatingTheTable() { diff --git a/src/Migrator/Providers/CatalogDefaultValue.cs b/src/Migrator/Providers/CatalogDefaultValue.cs index f7f23025..422ee9e8 100644 --- a/src/Migrator/Providers/CatalogDefaultValue.cs +++ b/src/Migrator/Providers/CatalogDefaultValue.cs @@ -15,7 +15,7 @@ internal static object Parse(string source, DbType type) while (HasOuterParentheses(value)) value = value[1..^1].Trim(); if (value.Equals("NULL", StringComparison.OrdinalIgnoreCase)) return null; if (value.StartsWith("N'", StringComparison.OrdinalIgnoreCase)) value = value[1..]; - if (value.StartsWith("'") && value.EndsWith("'")) + if (System.Text.RegularExpressions.Regex.IsMatch(value, @"\A'(?:[^']|'')*'\z")) { var literal = value[1..^1].Replace("''", "'"); if (type is DbType.Date or DbType.DateTime or DbType.DateTime2 && DateTime.TryParse(literal, CultureInfo.InvariantCulture, DateTimeStyles.None, out var date)) diff --git a/src/Migrator/Providers/Impl/SQLite/SQLiteConstraintParser.cs b/src/Migrator/Providers/Impl/SQLite/SQLiteConstraintParser.cs index 777153ee..c5c4f983 100644 --- a/src/Migrator/Providers/Impl/SQLite/SQLiteConstraintParser.cs +++ b/src/Migrator/Providers/Impl/SQLite/SQLiteConstraintParser.cs @@ -175,7 +175,8 @@ private static List Tokenize(string sql) else if (sql[i] is '(' or ')' or ',' or '.') { result.Add(new Token(sql[i++].ToString(), start, i)); } else { - while (i < sql.Length && !char.IsWhiteSpace(sql[i]) && sql[i] is not ('(' or ')' or ',' or '.' or '\'' or '"' or '`' or '[')) i++; + while (i < sql.Length && !char.IsWhiteSpace(sql[i]) && sql[i] is not ('(' or ')' or ',' or '.' or '\'' or '"' or '`' or '[') && + !(i + 1 < sql.Length && ((sql[i] == '/' && sql[i + 1] == '*') || (sql[i] == '-' && sql[i + 1] == '-')))) i++; result.Add(new Token(sql[start..i], start, i)); } } From 11d6083927c29382c8166bfef238dfb8e2cb0e77 Mon Sep 17 00:00:00 2001 From: jogibear9988 Date: Tue, 22 Sep 2026 20:24:05 +0200 Subject: [PATCH 27/34] Preserve constraint details and reject ignored Oracle index options Read SQL Server nonclustered primary-key metadata from the backing index type.

Add Hana dialect/provider registration, native type rendering, positional parameters, schema-aware catalog readers, explicit constraints/FK actions, ordinary indexes, column/table alterations, history support and structured create/add preview. Replace the prerequisite-only workflow with a mandatory Hana job in the complete database matrix. Add eight actual-engine tests covering owned/caller connections, imperative/fluent/preview behavior, constraints and metadata, schema qualification, data rollback, restart/downgrade/read-only planning and unsupported capabilities. Keep SAP dependencies in tests/hosts; the core has no driver package dependency. Do not claim transactional DDL, whole-session transactions, native locks, tenant administration or unimplemented specialized schema features. Document the exact provider scope and retain qualification evidence. Other additional FluentMigrator engines remain deferred until real CI infrastructure is available. Validation: solution build; 87 unit and 197 SQLite tests pass locally. The newly mandatory Hana matrix job must validate the provider itself before support is accepted; the prerequisite probe alone is not sufficient. --- .github/scripts/start-database.sh | 1 + .github/scripts/start-hana.sh | 28 +++ .github/scripts/test.ps1 | 6 +- .github/scripts/verify-test-coverage.py | 2 +- .github/workflows/dotnetpull.yml | 2 +- .github/workflows/hana-qualification.yml | 72 ------- docs/additional-database-qualification.md | 32 ++- src/Migrator.Tests/Migrator.Tests.csproj | 1 + .../Providers/Hana/HanaProviderTests.cs | 175 ++++++++++++++++ src/Migrator/Framework/Fluent/Operations.cs | 4 +- src/Migrator/ProviderFactory.cs | 2 + .../Providers/Impl/Hana/HanaDialect.cs | 58 ++++++ .../Impl/Hana/HanaTransformationProvider.cs | 194 ++++++++++++++++++ src/Migrator/Providers/ProviderTypes.cs | 1 + 14 files changed, 495 insertions(+), 83 deletions(-) create mode 100644 .github/scripts/start-hana.sh delete mode 100644 .github/workflows/hana-qualification.yml create mode 100644 src/Migrator.Tests/Providers/Hana/HanaProviderTests.cs create mode 100644 src/Migrator/Providers/Impl/Hana/HanaDialect.cs create mode 100644 src/Migrator/Providers/Impl/Hana/HanaTransformationProvider.cs diff --git a/.github/scripts/start-database.sh b/.github/scripts/start-database.sh index 7bb5d15a..b71442de 100644 --- a/.github/scripts/start-database.sh +++ b/.github/scripts/start-database.sh @@ -11,6 +11,7 @@ pull() { } case "$database" in Unit|SQLite) exit 0 ;;

Resolve the two failures: SAP exposes HanaFactory.Instance with a private constructor, and HANA does not permit LOWER(...) as a column default. Factory discovery now honors the standard public singleton field/property before constructor fallback. Exercise CURRENT_TIMESTAMP raw defaults through imperative, fluent and generated SQL paths, including catalog round trips and persisted timestamp values. Use HANA's complete ALTER column definition for default changes, replace removed defaults with DEFAULT NULL, and emit NULL when relaxing nullability. Extend the actual-engine alteration test to verify both changed/defaultless inserts and NOT NULL -> NULL transitions. This follows SAP's documented ALTER syntax. Validation: solution build and 87 unit tests pass locally. Existing actual-engine run 35767879821 identified the failures; all other database jobs passed.

Document RawSql defaults, semantic collation limits, effective scopes and the actual-engine admission gate for additional database providers. Refresh the framework comparison's source pin and SQLite constraint/index semantics; distinguish implemented v13 work from future design candidates in the migration guide. Set core, optional DI integration and CLI package metadata to 13.0.0-preview.1 and the core assembly/file versions to 13.0.0.0. Enable generated core version metadata while preserving manually declared title/description. No package is published. Validation: rebuilt solution and 87 unit tests; extracted matching README/homepage C# quick start compiled and migrated SQLite; fluent sample exercised preview, migration and automatic reversal. Inspected the homepage on desktop and a 390-pixel mobile viewport, confirmed no document overflow, and retained scrolling code blocks. Packed the v13 CLI locally.

Pin comparison source links to eabec55 and link the actual HANA matrix; retain Redshift, Snowflake and Db2 for IBM i as deferred until real CI endpoints exist. Distinguish unreleased source from NuGet and document the custom-host requirement for SAP's driver, HANA default-expression restrictions and DDL autocommit. Refresh the 81-issue audit with the v13 explicit-constraint resolution of #132, which remains open until merge. Remove the obsolete SQL Server test named as a uniqueness-removal regression that no longer created uniqueness; behavioral preservation/removal and duplicate-data tests already cover the replacement API. Correct the removed SchemaBuilder link, scope guidance, source-review links and local server test instructions, preserving semicolons when exporting credentials.
