SQL如何計算NEXT_RUN_DATE作業計劃？

Question

我必須手工計算下一次工作的日期，你能幫助我嗎？

Answer 1

得到一份工作下次運行日期，你可以使用然後sysschedules和sysjobschedules表

檢查next_run_date和next_runtime列從表sysjobschedules

next_run_date INT下一個日期上 工作計劃運行。日期 格式爲YYYYMMDD。

next_run_time int 作業計劃運行的時間。時間是 格式化HHMMSS，並使用24小時 時鐘。

看到這個劇本

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存儲過程，得到相同的信息。

UPDATE

如果你需要計算手動next_run_date必須檢查sysschedules表，看到了freq_interval的，的freq_subday_type，freq_subday_interval，freq_relative_interval，freq_recurrence_factor，active_start_date的數據，active_start_time列確定的公式。

檢查此link以查看使用示例。

Answer 2

簡單的答案是沒有單個公式 - 它隨freq_type的值而變化。

This看起來像一個體面的替代來源，你試圖編寫的查詢類型。

檢查這一項：

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

AND

-- 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

here是一個非常好的腳本，在那裏你可以得到下次運行日期。
