[Bug]: All the database names in `sys.databases` are set to “master”

[MasayukiOzawa]

Container image tag

sqldbpreview-dpgaeqhmgphzd4bk.azurecr.io/azure-sql/db-dev:latest

Host OS

Windows 11 (x86_64)

Container runtime and version

Docker version 29.1.3, build f52814d

What happened

When I connect to the master database and query sys.databases, all database names are displayed as “master.”
I was able to resolve this to the correct database names by using the DB_NAME() function.

Steps to reproduce

In environments launched with MSSQL_PID=Developer, the system database appears to display unexpected content.

You can reproduce this using the following command.

docker run -it --rm --name sqldbdev --publish 127.0.0.1:50001:1433 --env ACCEPT_EULA=Y --env MSSQL_PID=Developer --env "MSSQL_SA_PASSWORD=$ENV:SQLPASS" sqldbpreview-dpgaeqhmgphzd4bk.azurecr.io/azure-sql/db-dev
