SHOW GRANTS

语法说明

使用 SHOW GRANTS 语句显示用户的所有授权信息。SHOW GRANTS 语句显示使用 GRANT 命令分配给用户的权限。

使用 SHOW GRANTS 语句需要拥有查询 mo_catalog 库下所有表的 SELECT 权限，但显示当前用户的权限和角色除外。

要为 SHOW GRANTS 命名帐户或角色，即使用与 GRANT 语句相同的格式，例如：

1. show grants for 'root'@'localhost';

语法结构

1. > SHOW GRANTS FOR {username[@hostname] | rolename};

示例

1. create role role1;
2. grant all on table *.* to role1;
3. grant create table, drop table on database *.* to role1;
4. create user user1 identified by 'pass1';
5. grant role1 to user1;
6. > show grants for 'user1'@'localhost';
