AS 
    DECLARE @Returns BIT 
    SET @Returns =         


        

Answer 1

IF EXISTS(SELECT TransNo FROM [PARTABLE] WHERE TransNo = @TransNo and fpart = @fpart
        BEGIN                       
            DELETE FROM PARTABLE 
                        WHERE TransNo = @TransNo and fpart = @fpart

            SELECT @TransNo AS RETURNVAL
        END
        ELSE
        BEGIN
             SELECT 0 AS RETURNVAL
        END
