    Description

      MariaDB 12.1 introduced a change to constraint naming behavior through MDEV-28933. This modification affects metadata queries that rely on joins between INFORMATION_SCHEMA.KEY_COLUMN_USAGE and INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS tables.

      Previously, joins could be performed using only the three columns: CONSTRAINT_CATALOG, CONSTRAINT_SCHEMA, and CONSTRAINT_NAME. However, due to this change, queries must now include TABLE_NAME as an additional join condition to ensure accurate results.
      This breaking change specifically impacts the following metadata operations:

      • getExportedKeys()
      • getImportedKeys()
      • getCrossReference()
