Subject [jira] Commented: (DERBY-156) Delete with alias on column fails
Date Wed, 02 Mar 2005 04:35:48 GMT
     [ http://issues.apache.org/jira/browse/DERBY-156?page=comments#action_60025 ]
     
Bernd Ruehlicke commented on DERBY-156:
---------------------------------------

Yes, I agree - must be seen as a new feature.

I got into the trouble when having a (generated) statement like

DELETE FROM myTable x WHERE NOT EXISTS (SELECT * FROM mySecondTable y WHERE y.Col1 = x.Coln)

I may get around this by decomposing this statement.

cooks down to that this should work but dose not.
