Re: Changing column format

David,
 You can alter table drop constraint to get rid of the current pk and then create a new one using the column you desire. Ron

I create a table to store user account information and set "userid" column
to be primary key. I now want to set "username" to be primary key instead
of "userid", how do I change it? There are couple hundreds of records in
table. Please advise.

Thanks,
David
