Powershell - 用户映射 SQL Server 2012 [英] Powershell - User Mapping SQL Server 2012

问题描述

我正在尝试为不同的登录帐户编写用户映射脚本.我已经编写了创建用户和单个服务器角色的脚本，但我不知道如何使用 Powershell 设置用户映射，我还需要设置 Database Role members，特别是 db_backupoperator

I am trying to script User Mapping for different Login accounts. I have scripted the creation of users and individual server roles, but I can't figure out how to set User Mapping with Powershell, I will also need to set the Database Role membership, in Particular, db_backupoperator

有人知道如何用 Powershell 做到这一点吗?

Anyone know how to do this with Powershell?

推荐答案

假设您的登录名已创建

## Creating database user and assigning database role    

#get variables
$instanceName = "yourInstance"
$loginName = "testLogin"
$dbUserName = "testUserName"
$databasename = "tempdb"
$roleName = "db_backupoperator"
$server = New-Object -TypeName Microsoft.SqlServer.Management.Smo.Server -ArgumentList $instanceName

#add a database mapping
$database = $server.Databases[$databasename]
$login = $server.Logins[$loginName]
if ($database.Users[$dbUserName])
{
    $database.Users[$dbUserName].Drop()
}
$dbUser = New-Object `
-TypeName Microsoft.SqlServer.Management.Smo.User `
-ArgumentList $database, $dbUserName
$dbUser.Login = $loginName
$dbUser.Create()

#assign database role for a new user
$dbrole = $database.Roles[$roleName]
$dbrole.AddMember($dbUserName)
$dbrole.Alter
