如何计算每个Status在每个Schedule中花费的总时间？

结果应如下所示：

ScheduleID     |WorkerStatusID    |TimeSpent
--------------------------------------------
202            |1                 |06:30:00
202            |2                 |00:15:00
202            |3                 |00:30:00
202            |4                 |00:15:05
224            |1                 |06:45:00
224            |2                 |00:20:00
224            |3                 |00:25:00
224            |4                 |00:10:05

Answer 1

尝试一下（我的数字与您的样本结果不匹配）：

with mytablelead(ScheduleLogID, ScheduleID, WorkerStatusID, StatusLogDatetime, leadtime) as
(
select ScheduleLogID, ScheduleID, WorkerStatusID, StatusLogDatetime,
    lead(StatusLogDatetime) over(partition by ScheduleID order by StatusLogDatetime) as leadtime
from mytable
)
select ScheduleID, WorkerStatusID, sum(datediff(ss, StatusLogDatetime, leadtime)) as totalsecs
from mytablelead
group by ScheduleID, WorkerStatusID
order by ScheduleID, WorkerStatusID

Answer 2

不如上述方法那么优雅，但这是我想要的：

SELECT OUTSL1.ScheduleID,
       OUTSL1.StartStatus as [Worker Status],
       SUM(DATEDIFF(s,OUTSL1.StartTime, OUTSL1.StopTime)) as TimeSpent
FROM (SELECT [SL].ScheduleID
            ,[SL].StatusLogDatetime as StartTime
            ,LEAD([SL].StatusLogDatetime) over(partition by [SL].ScheduleID order by [SL].StatusLogDatetime ASC) as StopTime
            ,[SL].WorkerStatusID as StartStatus
            ,LEAD([SL].WorkerStatusID) over(partition by [SL].ScheduleID order by [SL].StatusLogDatetime ASC) as StopStatus
      FROM [iFacility].[dbo].[tblScheduleLogs] as [SL]) as OUTSL1
WHERE OUTSL1.StartStatus = 1
GROUP BY ScheduleID, StartStatus

通过上面的查询，我设法为Status = 1计算了它。对于其他所有查询，Statuses，最后是UNION，我都做了同样的事情。

计算花费在每个状态上的时间
