Hi Todd,

In VFP9 it is simpler, but in VFP you can use:
SELECT NVL(A.Item, b.Item), count(a.Item)+Count(b.Item) FROM Items A FULL JOIN Items2 B ON .F. GROUP BY 1
Walter,





>Is it possible to write 1 select statement in VFP that will return the frequency of items across two tables. For Instance I have two separate tables that contain information about the use of a product. I want to see the total frequency of each item across the tables
