晚上加班调用一个远程拷贝的本地Mysql的储存过程，报错：[Err] 1449 - The user specified as a definer ('admin_isbox'@'localhost') does not exist
凭借以前经常见到的root@localhost报错，给root赋值所有权限：
grant all privileges on *.* to root@"%" identified by ".";
flush privileges;
发现无效。
可能数据库没有此用户：
select user,host from mysql.user;
没找到此用户，但是报错出现了这个用户。寻求谷歌后，找到解决方法：
SELECT definer,type FROM mysql.proc GROUP BY definer,type;
UPDATE mysql.proc SET definer='root@localhost' WHERE definer = '*username*@localhost';
重启数据库，OK
[Err] 1449 - The user specified as a definer ('admin_isbox'@'localhost') does not exist
