Research direction
Investigate the codebase to locate the validation logic for database table names and the handling of custom SQL joins. Look for settings where table name is optional and determine why the option has no effect during joins. Check relevant files like configuration classes or SQL builders. Review any existing comments or closed issues for additional context.
