>             Project: Torque

> It shall be possible to execute statements like
> SELECT * FROM table1, (SELECT * FROM table2 WHERE xxx) t2 WHERE table1.id = t2.id
> (I know this example can be rewritten as a simple join, the actual use case is more complicated)
> In the case of the Criteria object, this would suggest a call sequence like 
> criteria.addAlias("t2", subCriteria);
> criteria.addJoin("t2.id", Table1Peer.ID);
