SQL如何计算NEXT_RUN_DATE作业计划？

Question

我必须手工计算下一次工作的日期，你能帮助我吗？

Answer 1

得到一份工作下次运行日期，你可以使用然后sysschedules和sysjobschedules表

检查next_run_date和next_runtime列从表sysjobschedules

next_run_date INT下一个日期上 工作计划运行。日期 格式为YYYYMMDD。

next_run_time int 作业计划运行的时间。时间是 格式化HHMMSS，并使用24小时 时钟。

看到这个剧本

Select sched.*,jobsched.* FROM msdb.dbo.sysschedules AS sched 
inner Join msdb.dbo.sysjobschedules AS jobsched ON sched.schedule_id = jobsched.schedule_id 

，或者您可以使用msdb.dbo.sp_help_jobschedule存储过程，得到相同的信息。

UPDATE

如果你需要计算手动next_run_date必须检查sysschedules表，看到了freq_interval的，的freq_subday_type，freq_subday_interval，freq_relative_interval，freq_recurrence_factor，active_start_date的数据，active_start_time列确定的公式。

检查此link以查看使用示例。

Answer 2

简单的答案是没有单个公式 - 它随freq_type的值而变化。

该网站似乎在撰写的时候已关闭，但有一篇文章在http://www.sqlmag.com/Article/ArticleID/99593/sql_server_99593.html，其中介绍了如何导出此信息。不幸的是，该网站不允许谷歌缓存其内容，所以它不能被检索，直到该网站恢复为止

This看起来像一个体面的替代来源，你试图编写的查询类型。

检查这一项：

SELECT 

    J.NAME JOB, 

    DATEADD(SS,(H.RUN_TIME)%100,DATEADD(N,(H.RUN_TIME/100)%100,DATEADD(HH,H.RUN_TIME/10000,CONVERT(DATETIME,CONVERT(VARCHAR(8),H.RUN_DATE),112)))) 
    JOB_STARTED, 

    DATEADD(SS,((H.RUN_DURATION)%10000)%100,DATEADD(N,((H.RUN_DURATION)%10000)/100,DATEADD(HH,(H.RUN_DURATION)/10000,DATEADD(SS,(H.RUN_TIME)%100,DATEADD(N,(H.RUN_TIME/100)%100,DATEADD(HH,H.RUN_TIME/10000,CONVERT(DATETIME,CONVERT(VARCHAR(8),H.RUN_DATE),112)))))))

    ELSE CONVERT(DATETIME,CONVERT(VARCHAR(8),'19000101'),112) END NEXT_RUN

    J.JOB_ID = S.JOB_ID 
AND 
    H.JOB_ID = M.JOB_ID 
AND 
    H.INSTANCE_ID = M.INSTANCE_ID 

-- IF you want to check all job for today then uncomments below 

-- AND 

--  RUN_DATE = (YEAR(GETDATE())*10000) + (MONTH(GETDATE()) * 100) + DAY(GETDATE()) 
ORDER BY NEXT_RUN 

Answer 4

here是一个非常好的脚本，在那里你可以得到下次运行日期。
