Question

所以我无法让企业经理这样做......如果我是，我甚至不会问这个问题。所以我想知道是否有办法通过TSQL执行将用户映射到特定数据库并授予他们“所有者”权限的命令。

...谢谢

Answer 1

更改登录的默认数据库：

alter login <loginname> with default_database = <dbname>;

在数据库中为给定登录创建用户：

use <dbname>;
create user <username> from login <loginname>;

建立db_owner组的用户成员：

use <dbname>
exec sp_addrolemember 'db_owner', '<username>';

登录数据库'dbo'：

alter authorization on database::<dbname> to <loginname>;

Answer 2

正式地说，您要创建映射到登录的数据库用户。为此，您可以使用：

Create User <username> For LOGIN <loginname>

这显然要求登录存在。之后你会打电话给：

exec sp_addrolemember 'db_owner', <username>

这假定您连接到数据库的帐户有权将成员添加到db_owner角色。

Answer 3

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

Answer 4

CREATE USER和sp_addrolemember

使用：在SQL Server上创建使用sysadmin权限登录：AdminAPI

        SQLserverAPI.CreateNewDatabaseSqlserver("yourServer.cloudapp.net,1433", "databaseName", "AdminAPI", "password*");
        SQLserverAPI.CreateLoginInSqlServer("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "My_Login", "password*");
        SQLserverAPI.CreateUserInDatabase("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "databaseName", "User1", "My_Login");
        SQLserverAPI.AddUserToRoles("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "databaseName", "db_datareader", "User1");
        SQLserverAPI.AddUserToRoles("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "databaseName", "db_datawriter", "User1");
        SQLserverAPI.AddUserToRoles("yourServer.cloudapp.net,1433", "AdminAPI", "password*", "databaseName", "db_owner", "User1");

当然，您通常不希望向用户授予所有者权限。这就是DBA世界中我们这些人所说的“坏事”。

TSQL将用户映射到数据库
