在遷移或升級SQL Server數據庫服務器時，很多場景下我們不能還原msdb，所以我們必須手工遷移SQL Server相關作業。如果手工生成每一個作業的腳本話，費時又費力，其實SQL Server中有好幾種方法可以批量生成作業腳本的方法， 下面介紹一下。

1：SSMS客戶端工具批量生成創建作業腳本

1：在SSMS—>SQL Server Agent下，單擊Jobs。

2： 按快捷鍵F7，在Object Explorer Details裏面，你會看到所有的作業

3： 全選所有作業（CTRL+A）,然後右鍵單擊“Script Job as

這個方法其實是非常簡潔方便的。不足之處就是所有作業的腳本位於同一個Script，沒有按作業名生成相關對應的腳本。

2：使用PowerShell腳本生成所有作業的腳本

有一個現成的PowerShell腳本,相關介紹以及腳本下載具體參考下面鏈接：

https://gallery.technet.microsoft.com/scriptcenter/How-to-get-the-of-all-the-81859696

PS C:\Users> M:\GetJobScripts\GetAllAgentJobs.ps1

cmdlet GetAllAgentJobs.ps1 at command pipeline position 1

Supply values for the following parameters:

ServerName: YourServerName

FilePath: M:\GetJobScripts

Scripting out xxxxxxxxxxxx successfully!

Scripting out xxxxxxxxxxxx successfully!

.........................................

使用該PowerShell腳本可以生成各個作業的各自腳本。非常簡潔方便。不過該腳本要求Windows PowerShell 2.0或更高的版本，另外，有些平臺是沒有測試過的，需要參考上面鏈接說明。 GetAllAgentJobs.ps1的腳本如下：

Param(

[Parameter(Mandatory = $true, position = 0)][string] $ServerName,

[Parameter(Mandatory = $true, position = 1)][string] $FilePath

)

if(Test-Path $FilePath)

{

        #check if the instance name is available on the server

         [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") |Out-Null

         $srv = New-Object (‘Microsoft.SqlServer.Management.Smo.Server‘) $ServerName 

         if($ServerName.contains($env:COMPUTERNAME) -and ($srv.VersionString))

         {

            $jobs = $srv.JobServer.Jobs | Where-Object {$_.category -notlike "*repl*" -and $_.category -notlike "*shipping*" -and $_.category -notlike "*Maintenance*" }  

            ForEach ( $job in $jobs) 

            { 

               $jobname = $FilePath +‘\‘ + $job.Name.replace(" ","_").replace("\","_").replace("[","_").replace("]","_").replace(".","_").replace(":","_").replace("*","_") + ".sql" 

              $job.Script() | Out-File $jobname 

                Write-Host ‘Scripting out ‘ $job ‘ successfully!‘

            }

         }

        else 

        {

        Write-Host ‘The server name you entered is not available!‘

        }

}

else

{

Write-Host ‘The path does not exist, please retype again!‘

}

方法3：通過SqlDmo組件相關函數生成數據庫對象腳本，不過有些版本由於沒有安裝"Backward Compatibility Components" 導致該腳本不能創建相關腳本文件，個人測試時也遇到不少問題，有興趣可以試試。
