Subject [jira] [Created] (TORQUE-187) Allow joins with subselects in the FROM clause
Date Tue, 13 Mar 2012 12:49:37 GMT
Allow joins with subselects in the FROM clause
----------------------------------------------

                 Key: TORQUE-187
                 URL: https://issues.apache.org/jira/browse/TORQUE-187
             Project: Torque
          Issue Type: New Feature
          Components: Runtime
    Affects Versions: 4.0
            Reporter: Thomas Vandahl


It shall be possible to execute statements like

{code:sql}
SELECT * FROM table1, (SELECT * FROM table2 WHERE xxx) t2 WHERE table1.id = t2.id
{code}

(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 

{code}
criteria.addAlias("t2", subCriteria);
criteria.addJoin("t2.id", Table1Peer.ID);
{code}
