SHOW GRANTS

语法

SHOW GRANTS [FOR user|role]

描述

SHOW GRANTS 语句列出了授予特定用户或角色的权限。

用户

该语句列出了必须发出的 GRANT 语句或语句,以复制授予 MariaDB 用户帐户的权限。帐户的命名方式与 GRANT 语句相同;例如,'jeffrey'@'localhost'。如果您只指定帐户名称的用户名部分,则使用主机名部分 '%'。有关指定帐户名称的其他信息,请参见 GRANT

SHOW GRANTS FOR 'root'@'localhost';
+---------------------------------------------------------------------+
| Grants for root@localhost                                           |
+---------------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION |
+---------------------------------------------------------------------+

要列出授予您用于连接到服务器的帐户的特权,您可以使用以下任何语句:

SHOW GRANTS;
SHOW GRANTS FOR CURRENT_USER;
SHOW GRANTS FOR CURRENT_USER();

如果在 DEFINER 上下文中使用了 SHOW GRANTS FOR CURRENT_USER(或任何等效语法)(例如,在使用 SQL SECURITY DEFINER 定义的存储过程中),则显示的授权是定义者的授权,而不是调用者的授权。

请注意,自 MariaDB 10.3.4 起引入的 DELETE HISTORY 特权在运行 SHOW GRANTS 时显示为 DELETE VERSIONING ROWS,直到 MariaDB 10.3.15MDEV-17655)。

角色

SHOW GRANTS 还可用于查看授予 role 的特权。

示例

SHOW GRANTS FOR journalist;
+------------------------------------------+
| Grants for journalist                    |
+------------------------------------------+
| GRANT USAGE ON *.* TO 'journalist'       |
| GRANT DELETE ON `test`.* TO 'journalist' |
+------------------------------------------+

对于 PUBLIC

MariaDB starting with 10.11

GRANT ... TO PUBLICMariaDB 10.11 中引入,以将特权授予所有用户。SHOW GRANTS FOR PUBLIC 显示所有这些授权。

SHOW GRANTS FOR public;
+------------------------------------------------+
| Grants for PUBLIC                              |
+------------------------------------------------+
| GRANT ALL PRIVILEGES ON `dev_db`.* TO `PUBLIC` |
+------------------------------------------------+
