mysql回收权限不成功，请问如何破？

过程如下：

mysql> revoke all on *.* from 'levi'@'%';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> show grants for `levi`;
+-----------------------------------------------------------------------------------------------------------------------+
| Grants for levi@%                                                                                                     |
+-----------------------------------------------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'levi'@'%' IDENTIFIED BY PASSWORD '抱歉呀，这个我隐藏啦=  =~~~~~~~~~~~~~~~~~~~~' WITH GRANT OPTION |
| GRANT ALL PRIVILEGES ON `wordpress`.* TO 'levi'@'%' WITH GRANT OPTION                                                 |
+-----------------------------------------------------------------------------------------------------------------------+

那结果就是，登录levi这个用户之后，可以查看所有的数据库，只能操作wordpress这个数据库

我希望的是，登录levi这个用户之后，只能查看、操作wordpress这个数据库

自己找到解决办法了，删除用户，重新建
