导出作业时 SQL Server 生成的奇怪脚本

问题描述

我使用的是 SQL Server 2008 Enterprise.我正在使用 Management Studio -> Jobs -> Script Job as -> Drop and Create TO 功能来生成相关的 sql 语句，以便我可以从另一台计算机导入作业.

I am using SQL Server 2008 Enterprise. I am using Management Studio -> Jobs -> Script Job as -> Drop and Create TO feature to generate related sql statement so that from another computer I can import the job.

我的问题是，从生成的sql脚本来看，从一开始就有这样的输出，有一个硬编码的jobid——@job_id=N'3c5f83cd-e220-49ee-a1f1-40e37713ba1b'.我的困惑是，如果我们依赖这样的硬编码值，在另一台计算机上，jobid 可能是不同的值......所以导入另一台计算机可能会失败?

My question is, from the generated sql scripts, from the beginning there is output like this, there is a hard coded jobid -- @job_id=N'3c5f83cd-e220-49ee-a1f1-40e37713ba1b'. My confusion is if we dependent on such hard coded value, on another computer maybe jobid is a different value... So importing into another computer may fail?

USE [msdb]
GO

IF  EXISTS (SELECT job_id FROM msdb.dbo.sysjobs_view WHERE name = N'TestCleanupJob')
EXEC msdb.dbo.sp_delete_job @job_id=N'3c5f83cd-e220-49ee-a1f1-40e37713ba1b', @delete_unused_schedule=1
GO

这里是生成的整个 SQL Server 脚本，

here is the whole SQL Server scripts generated,

USE [msdb]
GO

/****** Object:  Job [TestJob]    Script Date: 08/03/2009 00:45:20 ******/
IF  EXISTS (SELECT job_id FROM msdb.dbo.sysjobs_view WHERE name = N'TestJob')

EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'[Uncategorized (Local)]'
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

END

DECLARE @jobId BINARY(16)

IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)'
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback
COMMIT TRANSACTION
GOTO EndSave
QuitWithRollback:
    IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION
EndSave:

GO

编辑 2:这里是我使用作业 ID 以外的作业名称的修复，

EDIT 2: here is my fix to use Job Name other than Job ID,

IF  EXISTS (SELECT name FROM msdb.dbo.sysjobs_view WHERE name = N'TestCleanupJob')
EXEC msdb.dbo.sp_delete_job @job_name=N'TestCleanupJob', @delete_unused_schedule=1
GO

推荐答案

您可以在 sp_delete_job 过程中使用@job_name 参数代替@job_id.

You can use @job_name parameter for sp_delete_job procedure instead of @job_id.
