Question

我正在尝试在PowerShell脚本中使用凭证连接。我试过了：

$credential = Get-Credential

和

$credential = $host.ui.PromptForCredential("Need credentials", "Please enter your user name and password.", "", "Domain")

但是当我执行查询时，我收到以下消息：

Invoke-SqlQuery -Query $Query -Server $SERVER -database $DataBase -credential $credential 
Exception calling "Open" with "0" argument(s): "Login failed for user '\sa'."
\Modules\InvokeSqlQuery\InvokeSqlQuery.psm1:155 char:14
+     $cnn.Open <<<< ();
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

即使我使用正确的凭据，也会失败。有没有人有同样的问题？ Invoke-SqlQuery调用

$cnn = New-SqlConnection $Server $Database $Credential $ConnectionTimeout

会产生错误。

顺便说一句，我想知道如何加载这个程序集：

new-object [System.Management.Automation.PSCredential]
New-Object : Cannot find type [[System.Management.Automation.PSCredential]]: make sure the assembly containing this type is loaded.

感谢。

Answer 1

要回答第二个问题:-)，包含PSCredential的程序集已经加载。它是PowerShell所需的程序集。试试这个：

$username = ConvertTo-SecureString username -AsPlainText -Force
$password = ConvertTo-SecureString pass!word -AsPlainText -Force
$cred = new-object management.automation.pscredential $username,$password

Answer 2

试试这个（PsSnapin：SqlServerCmdletSnapin100）：

$pwd = read-host -AsSecureString -Prompt "Password"

Invoke-Sqlcmd -Query $Query -Serverinstance $SERVER -database $DataBase –Username “MyLogin” –Password $pwd

凭据连接不起作用
