I heard that there was some talk of an ALTER TABLE <table> DROP COLUMN <col> in the hackers list a while ago. I would also like to see an ALTER TABLE <table> ADD COLUMN <col> AFTER <col>. I know it's not a production concern b/c I can simply use dump/restore but I'm just interested if it's coming some day ;) Brent --- Brent R.
