Hi RAM,

Dan already replied how to do this with GRANT and DENY. If you also must
keep the database owner and administrators from accidentally inserting
or deleting a row, add the following trigger:

CREATE TRIGGER NoInsertOrDelete
ON SingleRowTable
AFTER INSERT, DELETE
AS
IF @@ROWCOUNT = 0 RETURN
ROLLBACK TRANSACTION
RAISERROR ('Don''t add rows to or remove rows from this table!', 16, 1)
GO
