正在运行show grants;表示我以具有数据库所有特权的用户身份登录。

运行会show table status;导致错误。并且错误不显示我作为登录用户名！

就好像对于此命令，mysql忘记了我是谁。其他选择语句也可以正常工作。谁能解释一下？怎么修？谢谢。

更新…根据Tomalak的建议，我删除了该用户，并使用更充分的特权和密码重新创建了该用户。问题仍然存在。现在看起来像这样：

mysql> show grants;
+--------------------------------------------------+
| Grants for php@localhost                         |
+--------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'php'@'localhost' |

mysql> show table status;
