SMOを使用してPowerShellスクリプトを実行するとアセンブリが見つからない

データベース名、復元されたDB名、バックアップソース、データファイルの場所、ログファイルの場所をパラメーターとして取り、SQL Serverインスタンスでデータベースの復元を実行するスクリプトを作成しました。 PowerShell ISEから実行するとスクリプトは正常に機能しますが、PowerShellコンソールから実行すると欠落アセンブリエラーがスローされるか、SQLエージェントジョブをCmdExecまたはPowerShellタイプとして実行すると、用語がcmdlewhenエラーの名前として認識されません。

スクリプトでAdd-Typeを使用してアセンブリへのパスを追加しようとしましたが、Microsoft.SqlServer.Management.Smo.Server、Microsoft.SqlServer.Management.Smo.Restore ...という名前のアセンブリはありません。

私はPS newbとしてアイデアがありません。 SQLエージェントジョブステップ内でこのスクリプトを実行できるように、この問題を解決する方法についてのアドバイス、アイデアはありますか？

コマンドを使用してISEおよびコンソールでスクリプトを実行しています

.\RestoreDB_Script.ps1 -DatabaseName TestDB -NewDatabaseName TestDB_new -SourceDir V:\Backup -DataDir D:\Data -LogDir L:\Log

SQLエージェントジョブでのスクリプトの実行

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile  -ExecutionPolicy Bypass -Command C:\Script\RestoreDB_Script.ps1 -DatabaseName TestDB -NewDatabaseName TestDB_new -SourceDir V:\Backup -DataDir D:\Data -LogDir L:\Log

SQL Server PowerShell：SMOとPowerShellを使用してSQL Serverデータベースを復元する方法 にあるいくつかの情報を使用して、そのエラーを回避することができました。スクリプトの最上部に以下を追加してみてください

#load assemblies
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null
#Need SmoExtended for backup
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoExtended") | Out-Null
