    SELECT goods_id INTO goodsid FROM tb_return WHERE return_id=new.return_id;
    SELECT return_num INTO goodsnumber FROM tb_return WHERE return_id=new.return_id;
    UPDATE tb_goods SET goods_number=goods_number+goodsnumber WHERE goods_id=goodsid;
END;


// 調用
LOCK TABLE tb_sales WRITE;
CALL p_addreturn(1,47,'李四',2,2);

// 查詢
UNLOCK TABLE;
SELECT * FROM TB_RETURN;
SELECT * FROM TB_GOODS;

查詢結果：

// 修改
CREATE TRIGGER t_updatereturn
AFTER UPDATE ON tb_return FOR EACH ROW
BEGIN
    DECLARE goodsid INT(20);
    DECLARE goodsnumber INT(50);
    DECLARE goodsnumberold INT(50);

    SELECT goods_id INTO goodsid FROM tb_return WHERE return_id=new.return_id;
    SELECT return_num INTO goodsnumber FROM tb_return WHERE return_id=new.return_id;
    SELECT old.return_num INTO goodsnumberold FROM tb_return WHERE return_id=old.return_id;

    UPDATE tb_goods SET goods_number=goods_number+(goodsnumber-goodsnumberold) WHERE goods_id=goodsid;
END;


// 調用
LOCK TABLE tb_return WRITE;
CALL p_updatereturn(2,2*47,'李四',2,2,4);

// 查詢
UNLOCK TABLE;
SELECT * FROM TB_RETURN;
SELECT * FROM TB_GOODS;

查詢結果：

// 刪除
CREATE TRIGGER t_deletereturn
AFTER DELETE ON tb_return FOR EACH ROW
BEGIN
    UPDATE tb_goods SET goods_number=goods_number-old.return_num WHERE goods_id=old.goods_id;
END;

    SET querysql='select * from tb_return where 1=1 ';

    IF(goodsname IS NOT NULL) THEN
        SET goodsnamesql=CONCAT(' and goods_id in(select goods_id from tb_goods where goods_name like ''%',goodsname,'%'') ');
        set querysql=CONCAT(querysql,goodsnamesql);
    END IF;

    IF(categoryname IS NOT NULL) THEN
        SET categorynamesql=CONCAT(' and goods_id in(select goods_id from tb_goods where category_id in(select category_id from tb_category where category_name like ''%',categoryname,'%''))');
        SET querysql=CONCAT(querysql,categorynamesql);
    END IF;

    IF(starttime IS NOT NULL)AND(endtime IS NOT NULL) THEN
        SET timesql=CONCAT(' and return_date between ''',starttime,''' and ''',endtime,''' ');
        SET querysql=CONCAT(querysql,timesql);
    END IF;

    IF(minprice IS NOT NULL)AND(maxprice IS NOT NULL) THEN
        SET pricesql=CONCAT(' and return_sum between ',minprice,' and ',maxprice,' ');
        SET querysql=CONCAT(querysql,pricesql);
    END IF;

    SET @querysql=querysql;
    PREPARE querysqltemp FROM @querysql;
    EXECUTE querysqltemp;
    DEALLOCATE PREPARE querysqltemp;
