 mysql使用 过程函数 for in函数 批量修改数据

之前写的一个sql在某些版本mysql不能正常运行

BEGIN
    FOR aa IN (
        SELECT man.id as mid,com.id as cid,man.enterprise_name as mname
FROM erp_manufacturer_information man 
LEFT JOIN erp_commodity com ON man.enterprise_name = com.manufacture_name
    )        
LOOP
    UPDATE erp_commodity c
SET c.manufacture = aa.mid
WHERE
    t.id = aa.cid
        );
END LOOP;END;BEGIN FOR aa IN (
SELECT man.id as mid,com.id as cid,man.enterprise_name as mname
FROM erp_manufacturer_information man 
LEFT JOIN erp_commodity com ON man.enterprise_name = com.manufacture_name
)
LOOP
(
UPDATE erp_commodity c
SET c.manufacture = aa.mid
WHERE
    c.id = aa.cid
);
END LOOP;END;

改为标准存储过程后
