Subject [jira] Commented: (DERBY-883) Enhance GROUP BY clause to support expressions instead of just column references.
Date Sat, 19 Aug 2006 19:09:15 GMT
    [ http://issues.apache.org/jira/browse/DERBY-883?page=comments#action_12429218 ] 
            
Daniel John Debrunner commented on DERBY-883:
---------------------------------------------

Manish, can you fix up the patch so it works with the current state of the trunk. BaseJDBCTestCase
has moved and the changes to sqlgrammar.jaa and CoalesceFunctionNode do not apply cleanly.
If you can get this done this weekend then I will apply it.
