SHOW CREATE USER

SHOW CREATE USER 语句用于显示如何使用 CREATE USER 语法来重新创建用户。

{{< copyable "sql" >}}

SHOW CREATE USER 'root';

+--------------------------------------------------------------------------------------------------------------------------+
| CREATE USER 'root'@'%' IDENTIFIED WITH 'mysql_native_password' AS '' REQUIRE NONE PASSWORD EXPIRE DEFAULT ACCOUNT UNLOCK |
+--------------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)

mysql> SHOW GRANTS FOR 'root';
+-------------------------------------------+
| Grants for root@%                         |

MySQL 兼容性

• SHOW CREATE USER 的输出结果旨在匹配 MySQL，但 TiDB 尚不支持若干 CREATE 选项。尚未支持的选项在语句执行过程中会被解析但会被跳过执行。详情可参阅与 MySQL 安全特性差异。
