获取指定时间区间作业运行情况

背景：数据库服务器定期重启，想知道重启期间对作业的影响。通俗点就是服务器在重启的这段时间，有哪些作业计划运行，重启后是否需要手动执行这些作业？
第一次重启的时候，按照最笨的方式，把所有作业看一遍，然后人为判断有哪些作业将受到影响，再根据作业具体代码，确定是否需手动执行。后来老大说要弄个过程出来，通过传入起止时间参数，返回区间内的作业计划。
PS:参考各类资料，修改过很多遍，最后成型在6月初，很多细节上的修改自己也记不清楚了，一直懒得整理。先放上代码，以及效果图。

  2  * 说明：输入将来的起、止时间，得到时间区间内作业计划情况。主要包括：
  3          区间内首次执行时间、区间内末次执行时间、区间内执行次数、循环间隔、每天执行频率等。
  4  * 使用：DBA_Pro_GetJobSchedules '20140612 07:00:00.000','20140612 08:00:00.000'
  5  * 补充：手动运行作业，不会影响作业的计划调度。

执行过程将返回作业区间内首次执行时间、区间内末次执行时间、区间内执行次数、循环间隔、每天执行频率等信息

--15:31 2015/1/14 如果我们想把一个操作加到某个00:00:00执行作业的最后一步，我们先要把零点的那些作业找出来，此时可以利用msdb.dbo.sysjobschedules查询作业下次执行时间。注意msdb.dbo.sysjobschedules由后台线程每20分钟更新一次。

1 --下次执行时间(后台线程每20分钟更新)
2 select top 5 sj.name,sjs.next_run_date,sjs.next_run_time from msdb.dbo.sysjobs sj
3 inner join msdb.dbo.sysjobschedules sjs
4 on sj.job_id=sjs.job_id
5 where sj.enabled=1
6 and next_run_time=0--根据需求调整
7 order by sjs.next_run_date,sjs.next_run_time

对于执行频率很高的作业，msdb.dbo.sysjobschedules中的下次运行时间会滞后，如果需要实时的信息可以从msdb.dbo.sysjobactivity中获取。SQL Server代理服务每次重启后，将创建一个新的会话，并且 msdb 数据库的 sysjobactivity 表由所有现有的已定义作业填充。

1 --下次执行时间(实时更新)
2 select top 5 sj.name,sja.next_scheduled_run_date from msdb.dbo.sysjobs sj
3 inner join 
4 (select * from msdb.dbo.sysjobactivity
5 where session_id in(select max(session_id) session_id from msdb.dbo.sysjobactivity) 
6 )sja
7 on sj.job_id=sja.job_id
8 where sj.enabled=1
9 order by sja.next_scheduled_run_date

实时更新的代码对应“SQL Server 代理->作业活动监视器”的内容，里面可以设置筛选、排序。
