TSQL将用户映射到数据库
问题描述：
因此，我无法使用企业管理器来执行此操作......如果我是我，我甚至不会问这个问题。所以我想知道是否有通过TSQL执行命令将用户映射到特定数据库并授予他们“所有者”权限的方法。TSQL将用户映射到数据库
谢谢...

更改默认的数据库：
alter login <loginname> with default_database = <dbname>;
对于一个给定的登录在数据库中创建一个用户：
use <dbname>;
create user <username> from login <loginname>;
制作的db_owner组的用户成员：
use <dbname>
exec sp_addrolemember 'db_owner', '<username>';
进行数据库登录'dbo'：
alter authorization on database::<dbname> to <loginname>;
答
正式，你想创建一个映射到一个登录的数据库用户。要做到这一点，你可以使用：
Create User <username> For LOGIN <loginname>
这显然要求登录存在。之后，你会再调用：
exec sp_addrolemember 'db_owner', <username>
这假设与您正在连接到数据库的帐户有权限的成员添加到db_owner作用。登录的
答
USE [YourDB]
GO
CREATE USER [xyx] FOR LOGIN [xyz]
GO
ALTER USER [xyz] WITH DEFAULT_SCHEMA=[dbo]
GO
EXEC sp_addrolemember N'db_owner', N'xyz'
GO
答
当然，通常情况下，您不希望授予用户所有者权限。这就是我们DBA世界中的那些人所说的“一件坏事”。
