MS SQL批量生成作业脚本方法介绍总结

在迁移或升级SQL Server数据库服务器时，很多场景下我们不能还原msdb，所以我们必须手工迁移SQL Server相关作业。如果手工生成每一个作业的脚本话，费时又费力，其实SQL Server中有好几种方法可以批量生成作业脚本的方法， 下面介绍一下。

1：SSMS客户端工具批量生成创建作业脚本

1：在SSMS—>SQL Server Agent下，单击Jobs。

2： 按快捷键F7，在Object Explorer Details里面，你会看到所有的作业

3： 全选所有作业（CTRL+A）,然后右键单击“Script Job as”，然后选项“CREATE TO"就会生成所有作业的脚本。

这个方法其实是非常简洁方便的。不足之处就是所有作业的脚本位于同一个Script，没有按作业名生成相关对应的脚本。

2：使用PowerShell脚本生成所有作业的脚本

有一个现成的PowerShell脚本,相关介绍以及脚本下载具体参考下面链接：

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!

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

使用该PowerShell脚本可以生成各个作业的各自脚本。非常简洁方便。不过该脚本要求Windows PowerShell 2.0或更高的版本，另外，有些平台是没有测试过的，需要参考上面链接说明。 GetAllAgentJobs.ps1的脚本如下：

<#

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：通过SqlDmo组件相关函数生成数据库对象脚本，不过有些版本由于没有安装"Backward Compatibility Components" 导致该脚本不能创建相关脚本文件，个人测试时也遇到不少问题，有兴趣可以试试。
