hi folks,

Below is my current:

    @pcode varchar(max),
    @RETURNVALUE INT =0 OUT
)

as

DECLARE @COUNT INT

    BEGIN
        SELECT @COUNT=COUNT(*) FROM product where pcode=@pcode
            IF(@COUNT >0)
                BEGIN
                    SET @RETURNVALUE = 1;
                    RETURN @RETURNVALUE
                END
            ELSE
                BEGIN
                SELECT @COUNT=COUNT(*) FROM ProductColor where pcode=@pcode
                    IF(@COUNT >0)
                        BEGIN
                            SET @RETURNVALUE = 1;
                            RETURN @RETURNVALUE
                        END
                    ELSE
                        BEGIN
                            SELECT @COUNT=COUNT(*) FROM ProductColorSize where pcode=@pcode
                                IF(@COUNT >0)
                                    BEGIN
                                        SET @RETURNVALUE = 1;
                                        RETURN @RETURNVALUE
                                    END
                                ELSE
                                    BEGIN
                                        SET @RETURNVALUE = 0;
                                        RETURN @RETURNVALUE
                                    END

    END
