mysql存储过程批量多表删除_MySQL存储过程使用游标删除多表数据

注：游标只有在打开的时候才能使用，用完必须关闭之。

错误存储过程参数：

IN esCorCode varchar(20),IN intoOrderTableName varchar(30),IN outWareHouseTableName varchar(30),IN startTime varchar(50),IN endTime varchar(50)

错误存储过程：

修改方案：

通过游标查询视图获得游标需要的值。

-- ---------------------------------------------创建视图-------------------------------------开始---------------------------
