设置 触发器的账户不见了, 导致 触发器设置的标 写操作失败了

一、MySQL错误现象:

执行创建的存储过程或者触发器报:

ERROR 1449 (HY000): The user specified as a definer ('root'@'%') does not exist

二、错误原因:

这样由于创建存储过程或者触发器时间,指定的DEFINER为'root'@'%',而在MySQL的权限表(mysql.user)中,并不存在相关的user和host:

mysql> select host,user,password from mysql.user;
+-------------------------+------+----------+
| host                    | user | password |
+-------------------------+------+----------+
| localhost               | root |          |
| 127.0.0.1               | root |          |
| ::1                     | root |          |
| localhost               |      |          |
+-------------------------+------+----------+

三、解决方案:

执行下面SQL语句,为'root'@'%'授权即可:

grant all privileges on *.* to 'root'@'%' identified by ".";
flush privileges;
 
select host,user,password from mysql.user;

执行效果:
