>What is wrong with my sql statement ? I think maybe the other fields that I am creating at the same time are causing this. Should they be removed, I could use a SELECT DISTINCT ID....and then use an ALTER TABLE to add my other fields. ALSO I have been unable to recreate this behavior, but I can swear that it happend ( to my companies largest client, who received the same data three times and called everyone where I work to complain ! )

Did you try reindexing?

PS. Though it has nothing to do, I would suggest using SPACE(xxx) instead of strings of spaces.
