Oh yeah, and to drop the index, I just did this: alter table ftp drop index username
I don't ever remember making an index called username, but perhaps I did. Either way, it was a unique index against the login. I don't want to have unique logins because this table holds info about ftp from different ftp sites, so it doesn't make since to make a unique constraint on that field. Now, I will make it unique per (account,login). Maybe. Thanks again all, nix www.aeontrek.com ======================= "B.A.T.
