MySQL 如何显示为MySQL用户授予的权限

请使用SHOW GRANTS。以下是语法 –

SHOW GRANTS FOR 'yourUserName'@'yourHostName';

让我们从MySQL.user表中显示用户名和主机名。

mysql> select user,host from MySQL.user;

这将产生以下输出 –

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| Bob              | %         |
| Charlie          | %         |
| Robert           | %         |
| User2            | %         |
| mysql.infoschema | %         |
| mysql.session    | %         |
| mysql.sys        | %         |
| root             | %         |
| @UserName@       | localhost |
| Adam Smith       | localhost |
| Chris            | localhost |
| David            | localhost |
| James            | localhost |
| John             | localhost |
| John Doe         | localhost |
| User1            | localhost |
| am               | localhost |
| hbstudent        | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
+------------------+-----------+

用SHOW GRANTS来显示特定用户的授权 –

mysql> SHOW GRANTS FOR 'Robert'@'%'

这将产生以下输出 –

+----------------------------------------------------------------------+
| Grants for Robert@%                                                  |
+----------------------------------------------------------------------+
| GRANT USAGE ON *.* TO `Robert`@`%`                                   |
| GRANT ALL PRIVILEGES ON `sample`.* TO `Robert`@`%` WITH GRANT OPTION |
| GRANT EXECUTE ON `web`.* TO `Robert`@`%`                             |
