Hi, You need to drop the primary key constraint first, because primary key columns can't be altered:
drop table test; create table test(id int primary key); insert into test values(1), (2), (3); alter table test drop primary key; alter table test alter column id identity; Regards, Thomas On Wed, Feb 4, 2009 at 6:56 PM, rafael <[email protected]> wrote: > > I've already a column and it's a primary key.
