Summary

  • Fixes JDBC version returned by com.clickhouse.jdbc.metadata.DatabaseMetaDataImpl#getJDBCMajorVersion and com.clickhouse.jdbc.metadata.DatabaseMetaDataImpl#getJDBCMinorVersion. Previously was returning driver's version what is wrong. It should return spec supported version. We support 4.2 (what is almost fresh, next is 4.3)

Checklist

Delete items not relevant to your PR:

  • Closes #
  • Unit and integration tests covering the common scenarios were added
  • A human-readable description of the changes was provided to include in CHANGELOG
  • For significant changes, documentation in https://github.com/ClickHouse/clickhouse-docs was updated with further explanations or tutorials

Note

Low Risk
Small, localized metadata change with corresponding test update; only affects clients that read JDBC version from DatabaseMetaData.

Overview
Fixes JDBC version reporting in DatabaseMetaDataImpl so getJDBCMajorVersion()/getJDBCMinorVersion() return the supported JDBC spec version (4.2) instead of the ClickHouse driver’s own version.

Updates the integration test expectations in DatabaseMetaDataTest to assert the new 4/2 values.
