clickhouse 授权用户create temporary table权限


在ClickHouse中,授予用户创建临时表的权限,可以通过以下步骤实现: 1. 进入ClickHouse客户端,使用管理员账号登录。 2. 创建一个新角色,可以给予该角色创建临时表的权限。例如,执行以下语句创建一个名为`temporary_table_creator`的角色: ``` CREATE ROLE temporary_table_creator; ``` 3. 授予该角色的`CREATE TEMPORARY TABLE`权限: ``` GRANT CREATE TEMPORARY TABLE TO temporary_table_creator; ``` 4. 创建一个新用户并将其分配给该角色。例如,执行以下语句创建一个名为`user1`的用户,并分配给角色`temporary_table_creator`: ``` CREATE USER user1 IDENTIFIED BY 'password'; GRANT temporary_table_creator TO user1; ``` 现在,`user1`用户就具有了创建临时表的权限,可以在其会话中执行`CREATE TEMPORARY TABLE`语句来创建临时表。 这只是一个简单的示例,并且具体步骤可能因ClickHouse的版本和设置而有所不同。建议查阅ClickHouse的官方文档以获取更详细的信息。 [2024-01-10 10:03:54 | AI写代码神器 | 607点数解答]
