use [msdb]
 declare @job_name varchar(100)
 set @job_name = N'job_name'

--删除在计划里面的日志

delete sysmaintplan_log from sysmaintplan_subplans as subplans
 inner join sysjobs_view as syjobs on subplans.job_id = syjobs.job_id
 inner join sysmaintplan_log on subplans.subplan_id =sysmaintplan_log.subplan_id
 where (syjobs.name = @job_name)

--删除代理的作业

delete sysjobschedules from sysjobs_view v
 inner join sysjobschedules o on v.job_id=o.job_id where v.name=@job_name

--删除子计划

delete sysmaintplan_subplans from sysmaintplan_subplans as subplans
 inner join sysjobs_view as syjobs on subplans.job_id = syjobs.job_id
 where (syjobs.name = @job_name)
