"I don't think that is correct. It seems to do the subselect (return a set of rows) and THEN join the result to the outer select. A few responses have stated what you said - that EXISTS simply returns TRUE or FALSE. But I think that it must do this for each row in the outer select in the case where a join is occurring? Maybe Im wrong, I don't know SQL and it is elusive and powerful and complex so I don't understand all the subtleties. -----Original Message----- From: midrange-l-bounces@xxxxxxxxxxxx [mailto:m..."^^<http://www.w3.org/2001/XMLSchema#string>
