Now this problem is fixed but im publishing it for those pp that get this problem yet.
Right button on TCHARTABLE --> Design Table, and now go in Trigger, set all like the image.
Now delete all from Definition and put this script into.
Code:
BEGIN DECLARE @oldID INT DECLARE @newID INT SELECT @oldID = dwUserID FROM DELETED SELECT @newID = dwUserID FROM INSERTED IF(@oldID != @newID) BEGIN ROLLBACK; END END
