I don't see how this would be possible. The SELECT returns a row FOR EACH row in the table. If column2 had only 2 distinct values, then to do what you want you could ONLY return 2 rows. Distinct has to apply to all columns, otherwise it just doesn't make sense. Received on Tue Jan 06 1998 - 00:00:00 CET
