今天接到一开发反应,他们项目远程连接mysql ,有一张视图不能访问,出现以下错误:
因为每个项目都是单独分用户出去
[root@localhost ~]# mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

mysql> select * from v_challenge_rank;
ERROR 1449 (HY000): The user specified as a definer ('root'@'%') does not exist
mysql> select table_schema,table_name,definer from views;
+---------------+------------------+---------+
| table_schema | table_name | definer |

| wx_characters | v_challenge_rank | root@% |

因为mysql 用root用户创建视图,权限只会赋给创建视图的用户
这个视图不是他们项目组用户创建的,所以用户没有权限访问。
用该用户重建视图、恢复正常!
show create view c_challenge
create or replace view v_challenge as select * from challenge
