Important Changes
[jdbc-v2] SQL parser from v1 is ported to v2 to address multiple issues with SQL parsing. The ANTLR4-based parser is
still an option and will be developed further. The main difference between parses is completeness of their grammar:
JavaCC grabs only needed information and skips parsing of the rest (what makes it work for most cases) while ANTLR4
has more complete grammar and can detect type of some complex statements more accurate than JavaCC.
To use it set
com.clickhouse.jdbc.DriverProperties#SQL_PARSERtoANTLR4.(#2579). This fixes issue:
[repo] New artifact

maxRowsinStatementwhen additional settings were used to limit result set size.It caused problems with read-only users because such users may not change settings in most cases. Now when
maxRowsisset then
ResultSetwill skip extra rows. (#2582)But this approach doesn't work well with
0.9.xversions. Now major and minor versions are combined by shifting major.Patch version becomes a minor version. (#2410)
