RENAME USER

语法

RENAME USER old_user TO new_user
    [, old_user TO new_user] ...

描述

RENAME USER 语句用于重命名现有的 MariaDB 帐户。要使用它,您必须拥有全局 CREATE USER 权限或者对 mysql 数据库的 UPDATE 权限。每个帐户的命名格式与 CREATE USER 语句相同,例如 'jeffrey'@'localhost'。如果您只指定帐户名称的用户部分,则使用主机名部分为 '%'

如果任何旧用户帐户不存在或任何新用户帐户已经存在,则会出现 ERROR 1396 (HY000)。如果出现错误,则 RENAME USER 仍会重命名不会出错的帐户。

示例

CREATE USER 'donald', 'mickey';
RENAME USER 'donald' TO 'duck'@'localhost', 'mickey' TO 'mouse'@'localhost';
