存储过程/函数权限的问题解决（The user specified as a definer ('root'@'%') does not exist）

今天项目部署后测试时发现一个问题：

　　检查了数据库账号，都没错。

　　找百度，查询文档，给的解释是：MySQL中执行存储过程和函数时会检查过程的定义用户是否存在，以及是不是当前用户定义的，如果不存在，或者创建用户不对，即使当前用户有执行权限也会报错。

　　然后导出数据库，检查了函数定义：

DROP FUNCTION IF EXISTS `nextOrderNo`;
DELIMITER ;;
CREATE DEFINER=`root`@`%` FUNCTION `nextOrderNo`(`。。。
。。。。

　　发现了 DEFINER=`root`@`%，想起来之前函数定义是在本机数据库上添加的（习惯本机用root登录），导出的脚本自然是root的

　　查到原因就好解决了：

update mysql.proc set DEFINER='****@localhost' WHERE NAME='nextOrderNo' AND db='****';
