>You are saying that change Group By from 2 to 1,2 changes the result of the SQL Select, right? If so, I understand and agree. But it makes the SQL Select work without giving me the error. Also, since both 1 and 2 point to the same field (2 being just an upper case version of it), I don't think it changes the result, really.
