我正在尝试使用遍历所有数据库的 Powershell 7-Preview 执行 Powershell 脚本（7.0）文件，使用 DACPAC 文件更新它们并在所有数据库中执行其他 SQL Server 脚本。它在没有错误时工作正常，但是，如果在执行 Dacpac 文件时出错，它会给出以下错误并停止进一步执行脚本。

##[错误]无法部署包。 ##[error] PowerShell 以代码 '1' 退出。

关于我们如何在 Parallel 语句中优雅地捕获 PowerShell 中的错误并让脚本继续用于其他数据库的任何指针？Try-Catch 块似乎在这里不起作用。

我是 PowerShell 的新手。此 PowerShell 脚本是 DevOps 发布管道的一部分。

#.. Variables are defined here ..#
[string[]]$DatabaseNames = Invoke-Sqlcmd @GetDatabasesParams | select -expand name

[int]$ErrorCount = 0
$DatabaseNames | ForEach-Object -Parallel {
    try 
    {
        echo "$_ - 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}
     
        echo "$_ - Updating the scripts."
        $OngoingChangesScriptParams = @{
            "Database" = "$_"
            "ServerInstance" = "$ServerInstance"
            "Username" = "$DatabaseUsername"
            "Password" = "$DatabasePassword"
            "InputFile" ="$SystemWorkingDir\$OngoingChangesScriptLocation" 
            "OutputSqlErrors" = 1
            "QueryTimeout" = 9999
            "ConnectionTimeout" = 9999
        }

        Invoke-Sqlcmd @OngoingChangesScriptParams       
    }
    catch {
        $ErrorCount++
        echo "Internal Error. The remaining databases will still be processed."
        echo $_.Exception|Format-List -force
    }
}```

If the table contains data, the ALTER script will not work. To avoid this issue you must either: add a default value to the column, mark it as allowing NULL values, or enable the generation of smart-defaults as a deployment option.
