我在尝试执行以下 power-shell (7.0) 脚本时遇到此错误。此脚本使用 dacpac 文件和 SqlPackage.exe 更新所有数据库。

[string]$SqlPackagePath = "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\150\SqlPackage.exe"
[int]$ErrorCount = 0
$DatabaseNames | ForEach-Object -Parallel {
    
    echo "$_ - Updating database using DACPAC."
    
    dir -Path "C:\Program Files (x86)\Microsoft Visual Studio*" -Filter "SqlPackage.exe" -Recurse -ErrorAction SilentlyContinue | %{$_.FullName} {$using:SqlPackagePath /Action:Publish /tu:$using:DatabaseUsername /tp:$using:DatabasePassword /tsn:$using:ServerInstance /tdn:"$_" /sf:using:$DacpacLocation /p:BlockOnPossibleDataLoss=False}
        
  }

我是 powershell 脚本的新手。看起来问题似乎与传递参数的方式有关，所以我只是将 {} 放在参数周围，因为我收到 $using:SqlPackagePath 参数的另一个错误，但这似乎不起作用

无法将“System.String”类型的“somepath”值转换为“System.Management.Automation.ScriptBlock”类型。

您不能通过将参数嵌套在脚本块文字中来“转义”参数。

听起来你想做：

[string]$SqlPackagePath = "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\150\SqlPackage.exe"
[int]$ErrorCount = 0
$DatabaseNames | ForEach-Object -Parallel {
    
    echo "$_ - Updating database using DACPAC."

    # locate SqlPackage, otherwise default to `$SqlPackagePath` from calling scope
    $sqlPackageExe = dir -Path "C:\Program Files (x86)\Microsoft Visual Studio*" -Filter "SqlPackage.exe" -Recurse -ErrorAction SilentlyContinue |Select -First 1
    if(-not $sqlPackageExe){
        $sqlPackageExe = $using:SqlPackagePath
    }

    # use the `&` invocation operator to execute SqlPackage
    & $sqlPackageExe /Action:Publish /tu:$using:DatabaseUsername /tp:$using:DatabasePassword /tsn:$using:ServerInstance /tdn:"$_" /sf:$using:DacpacLocation /p:BlockOnPossibleDataLoss=False        
}
