An upgrade wouldn't cost anything. It would be free as part of your support contract.

Kevin,
Yes but does it work with data in the column?, I do not have 9i set up
yet. If it works as you describe with data in the column it will really
help with the multi million row tables that "they" want to rename a column after a release of a new lotto game. thanks,
for the test and update.
