Well my above syntax needs more coffee ;)
SELECT DISTINCT * FROM handle2 INTO ARRAY checkdup

handle2 has 1.3 million records with no duplicates. I ran this on my database server(dual 200Mz pentium with 132 MB of memory) and got 1307962 records selected in 1387.2 minutes. (and 3 users screaming the network locked up :))

Yes, this code is a resource hog... thats why I said I didnt know if it was the best way. I use this in a UDF I've setup as a maintenance process run directly on the server for my data warehouse, and I typically only run it overnight. With larger tables (like 2mil +) I sometimes get SQL memory error with it.

How would you handle this type of thing Edward?
