Teh only way is to drop the constraint and rebuild it. Obviously, that becomes a real problem if you have other tables referencing that one through FKs. It's easier to do the change through SSMS because it'll determine the dependencies and do it all for you.

I tried these codes:

USE test

GO

EXEC sp_rename N'tablo1.PK1', N'PK2', N'a1';

GO

but gives an error message

Msg 15249, Level 11, State 1, Procedure sp_rename, Line 75

Error: Explicit @objtype 'a1' is unrecognized.

If you help for a solution I would be grateful

Heh... well I'll be. Books Online has yet another documentation error. Under constraints, it specifically said that PK's needed to be dropped and rebuilt.
