ResultSetMetaData.getTableName returns table alias instead of real table name

ResultSetMetaData.getTableName returns table alias instead of real table name in for example following type of query.

SELECT id FROM t1 AS t1_alias

Currently ResultSetMetaData.getTableName would return t1_alias.

ResultSetMetaData.getTableName should return the real table name and this was fixed in the MySQL Connector/J some years back. An URL parameter called useOldAliasMetadataBehavior was introduced if someone wants to continue using the old behaviour.
