David: Can't remember if you ended up solving this, but I had an idea and it doesn't seem like it would be very hard:
1. Create 2 temp tables with half of the columns in each. Insert data into each of the tables, including those 4 or 5 "group by" columns you have. 2. Then just do an INTERSECT table1 WITH table2 FORMING endingtable That should give you a table with all the columns, and I don't think any of the commands would exceed the row length size. Karen
