在 PowerShell 脚本中设置 SQL 服务器凭据或使用凭据调用

Question

下面是我用于连接到 AWS SQL 服务器数据库的有效 PowerShell 脚本。如何在没有提示的情况下设置脚本中硬编码的凭据或使用凭据调用脚本？

我使用 PSCredential、credentials、Get-WmiObject、SqlConnection 尝试了互联网上的几个选项，但其中 none 有效。

      $srv = new-object "Microsoft.SqlServer.Management.SMO.Server" "myBox"          

      #set the credentials here
      #This sets the connection to mixed-mode authentication
      $srv.ConnectionContext.LoginSecure=$false; 

      #Prompt for user credentials 
      $credential = Get-Credential  

      #Deal with the extra backslash character 
      $loginName = $credential.UserName -replace("\","")  

      #This sets the login name  
      $srv.ConnectionContext.set_Login($loginName);  

      #This sets the password  
      $srv.ConnectionContext.set_SecurePassword($credential.Password)

      #test the connection
      $srv.Databases | Select name

    $SQLInstance = "Instance Name"
    $Database = "Database"
    $ID = "User ID" 
    $Password = "Password"

function Invoke-Sqlcommand 
{ 
    [CmdletBinding()] 
    param( 
    [Parameter(Position=0, Mandatory=$true)] [string]$ServerInstance, 
    [Parameter(Position=1, Mandatory=$false)] [string]$Database, 
    [Parameter(Position=2, Mandatory=$false)] [string]$Query, 
    [Parameter(Position=3, Mandatory=$false)] [string]$Username, 
    [Parameter(Position=4, Mandatory=$false)] [string]$Password, 
    [Parameter(Position=5, Mandatory=$false)] [Int32]$QueryTimeout=600, 
    [Parameter(Position=6, Mandatory=$false)] [Int32]$ConnectionTimeout=15, 
    [Parameter(Position=7, Mandatory=$false)] [ValidateScript({test-path $_})] [string]$InputFile, 
    [Parameter(Position=8, Mandatory=$false)] [ValidateSet("DataSet", "DataTable", "DataRow")] [string]$As="DataRow" 
    ) 

    if ($InputFile) 
    { 
        $filePath = $(resolve-path $InputFile).path 
        $Query =  [System.IO.File]::ReadAllText("$filePath") 
    } 

    $conn=new-object System.Data.SqlClient.SQLConnection 

    if ($Username) 
    { $ConnectionString = "Server={0};Database={1};User ID={2};Password={3};Trusted_Connection=False;Connect Timeout={4}" -f $ServerInstance,$Database,$Username,$Password,$ConnectionTimeout } 
    else 
    { $ConnectionString = "Server={0};Database={1};Integrated Security=True;Connect Timeout={2}" -f $ServerInstance,$Database,$ConnectionTimeout } 

    $conn.ConnectionString=$ConnectionString 

    #Following EventHandler is used for PRINT and RAISERROR T-SQL statements. Executed when -Verbose parameter specified by caller 
    if ($PSBoundParameters.Verbose) 
    { 
        $conn.FireInfoMessageEventOnUserErrors=$true 
        $handler = [System.Data.SqlClient.SqlInfoMessageEventHandler] {Write-Verbose "$($_)"} 
        $conn.add_InfoMessage($handler) 
    } 

    $conn.Open() 
    $cmd=new-object system.Data.SqlClient.SqlCommand($Query,$conn) 
    $cmd.CommandTimeout=$QueryTimeout 
    $ds=New-Object system.Data.DataSet 
    $da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd) 
    [void]$da.fill($ds) 
    $conn.Close() 
    switch ($As) 
    { 
        'DataSet'   { Write-Output ($ds) } 
        'DataTable' { Write-Output ($ds.Tables) } 
        'DataRow'   { Write-Output ($ds.Tables[0]) } 
    } 

} 


Invoke-Sqlcommand -ServerInstance $SQLInstance -Database $Database -Query "Query Goes here" -Username $ID -Password $Password

使用上述功能，您可以以纯文本形式传递用户名和密码，以便从 Powershell
