PowerShellを使用してデータベースを復元する（SQL Server）

Question

Powershellを使用してSQL Serverの復元プロセスを自動化する予定です。私は以下のPowerShellスクリプトを実行するとエラーは発生しません。どんな助けもありがとう。私は以下のpowershellスクリプトをうまく実行できません。右あなたの機能をオフ

[string] $SourceServer= ".\LOCAL"

Answer 1

GenericSqlQueryは、私が何に設定され表示されていない$1という変数が含まれています。特別な変数であるperlでは、PowerShellでは何かに設定するまで意味がありません。

前述のように、ロギングと検証を含むより効率的な方法が、リストアのためにdbatoolsモジュールを利用することです。 [開示：私はこのプロジェクトに貢献しています。] dbatoolsのcomands以下

#if not installed 
Install-Module dbatools 

# import it 
Import-Module dbatools 

# Restore it 
$sourceServer = '.\LOCAL' 
$DestServer = '.\LOCAL2' 
$RestoreDb = 'test1' 
$DataFolder='C:\Program Files\Microsoft SQL Server\MSSQL11.LOCAL2\MSSQL\DATA' 
$LogFolder='C:\Program Files\Microsoft SQL Server\MSSQL11.LOCAL2\MSSQL\DATA' 

# IF you need to get backup history 
Get-DbaRestoreHistory -SqlServer $sourceServer -Databases $RestoreDb | 
    Restore-DbaDatabase -SqlServer $DestServer -DestinationDataDirectory $DataFolder -DestinationLogDirectory $LogFolder 

# IF you just want to base it on backup folder, will SCAN complete folder 
$dbBackupPath = "\\servername\Backup\$RestoreDb" 
Restore-DbaDatabase -SqlServer $DestServer -Path $dbBackupPath -DestinationDataDirectory $DataFolder -DestinationLogDirectory $LogFolder
