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 10.3.15(MDEV-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 PUBLIC 在 MariaDB 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` | +------------------------------------------------+
