Just for the sake of interest, I think that this would have solved Jay's problem as well: WITH grouped AS (SELECT <fields> FROM <file> JOIN <other file> on <join criteria> GROUP BY <fields>) SELECT COUNT(*) FROM grouped First of all, does that make sense (I didn't test it). Secondly, are CTEs more efficient that the combination of CONCAT and DIGITS? ##################################################################################### Attention: The above message and/or attachment(s) is private and confidential and is intended only for the people for which it is addressed.
