Here is a possible modification of the existing stored procedure to handle self-referencing tables: -- Add a new variable to store the parent table ID DECLARE @ParentTableId INT = @ParentTableId; -- ... DECLARE curs_children CURSOR LOCAL FORWARD_ONLY FOR SELECT DISTINCT constid AS fkNameId, -- constraint name fkeyid AS cTableId FROM dbo.sysforeignkeys AS fk WHERE fk.fkeyid <> fk.rkeyid -- self-referencing tables AND fk.rkeyid = @ParentTableId; -- ... OPEN curs_children; DECLARE @fkNameId AS INT, @cTableId AS INT, @cColId AS INT, @pTableId AS INT, @pColId AS INT; -- Use a while loop to iterate through the self-referencing tables WHILE @@FETCH_STATUS = 0 BEGIN FETCH NEXT FROM curs_children INTO @fkNameId, @cTableId; IF @ExecuteDelete = 'Y' EXECUTE dbo.
