Question

我必须解决问题并且不知道该怎么做。我正在使用SQL Server 2012。

我有像这个架构的数据：

 -----------------------------------------------------------------------------------
   DriverId  | BeginDate | EndDate | NextBegin | Rest         | Drive Time | Drive
             |           |         | Date      | in minutes   | in seconds | KM            
 -----------------------------------------------------------------------------------
    integer     datetime   datetime   datetime    integer          integer     decimal(10,3)

   Rest in hours = EndDate - NextBeginDate
   Drive Time in Minutes = BeginDate - EndDate

   I have to search the BeginWorkDay first rest => 10 hours then
   BWD = BeginWorkDay
   EWD = EndWorkDay


   Do
     Compute how many minutes have the workDay (Diff between BWD and EWD) 
     SUM(DriveTime) as TotalDayDrive
     MAX(DriveTime) as MaxDriveDayPeriod
     SUM(Rest) as TotalDayRest
     Rest as NightRest
     MAX(Rest) as MaxDayRest
     Min(Rest) as MinDayRest
     SUM(TotalKM) as KM
   until next rest => 10 hours
   IF No More Rest EXIT DO
   Loop

Desired Result:

Driver     Plate    Begin Work Day            End Work Day             WorkDayTime(minu)

还有另一个主题＆＃34;如何积累价值tsql＆＃34;其中 Jerrad 编写了一个解决类似问题的魅力脚本，但我无法想象如何修改它来解决这个问题。

我有excel表中的数据，您可以从这里下载：Download Excel with data example and desired result

对不起我的英语，我希望你能理解并帮助我，提前谢谢你。

Answer 1

首先，您需要确定每天组成的行。我根据BeginDate和NextBeginDate将您的数据表加入到自身中。这为您提供了每天的开始和结束日期时间。我将结果存储在CTE中。

;with cte
as(
    select d.DriverId, 
    d.Matricula, 
    d.BeginDate DayBeginDate,
    (select MAX(EndDate) from Drive d3 where d3.DriverId = d.DriverId and d3.EndDate < DATEADD(d, 1, DATEDIFF(d, 0, d.BeginDate))) DayEndDate
    from Drive d 
    join Drive d2 on d.BeginDate = d2.NextBeginDate
    where d2.Rest > 600
)

现在只需根据CTE中的开始和结束日期时间从主数据表中选择各种聚合。

select d.DriverId, 
d.Matricula, 
d.DayBeginDate, 
d.DayEndDate,
DATEDIFF(N, d.DayBeginDate, d.DayEndDate) WorkDayTime,
(select SUM(d2.DriveTime) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate <= d.DayEndDate) DriveTime,
(select MAX(d2.DriveTime) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate <= d.DayEndDate) MaxDayDrive,
(select SUM(d2.Rest) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate < d.DayEndDate) TotalDayRest,
DATEDIFF(N, (select MAX(d2.EndDate) from Drive d2 where d2.DriverId = d.DriverId and d2.EndDate < d.DayBeginDate), d.DayBeginDate) NightRest,
(select MIN(d2.Rest) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate < d.DayEndDate) MinDayRest,
(select MAX(d2.Rest) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate < d.DayEndDate) MaxDayRest,
(select SUM(d2.DriveKM) from Drive d2 where d2.DriverId = d.DriverId and d2.BeginDate >= d.DayBeginDate and d2.EndDate <= d.DayEndDate) KM
from cte d 
group by d.DriverId, d.Matricula, d.DayBeginDate, d.DayEndDate
