Question

我有两张桌子。

MAP

Product    Channel  ProgDate   AdvTime
Air    Pix  30-04-2011  20:57:16
Air    Pix  30-05-2011  00:55:08

MBA

Product    Channel Date   ProgStartTime ProgEndTime
Air    Pix  30-04-2011  23:00:00   02:00:00
Air    Pix  30-04-2011  21:00:00   22:00:00

我必须检查MAP中的AdvtTime是否在StartTime＆amp;之间。 MBA表中的EndTime。

但是当持续时间（ProgStartTime - ProgEndTime）是一小时时，我需要一个+或 - 5分钟的缓冲区。

我需要 00:05:08 to match 23:00:00到02:00:00，以及 20:57:16 to match 21:00:00至22:00:00。

我使用以下查询加入

Select Distinct mb.Id as mbaid,mp.id as mapid, mp.Channel as Channel, mp.Product,mp.ProgDate, mp.AdvTime, mb.Channel,  mb.ProgStartTime, 
  mb.ProgEndTime, convert(time, dateadd(minute, datediff(minute, mb.progStartTime, mb.progEndTime), 0)) as timeDiff from map22 as mp inner join mba22 as mb 
on ((mp.ProgDate = mp.ProgDate and mp.Channel=mb.Channel and mp.Product=mb.Product)) 
 where (mp.ProgDate = mb.ProgDate
           AND AdvTime >= ProgStartTime
           AND (AdvTime <= ProgEndTime OR ProgEndTime < ProgStartTime))
          OR
          (mp.ProgDate = Dateadd(day,1,mb.ProgDate)
           AND ProgEndTime < ProgStartTime
           AND AdvTime <= ProgEndTime)
order by  mp.Id asc

Select  Distinct mb.Id as mbaid,
        mp.id as mapid, 
        mp.Channel as Channel, 
        mp.Product,
        mp.ProgDate, 
        mp.AdvTime, 
        mb.Channel,  
        mb.ProgStartTime, 
        mb.ProgEndTime, 
        convert(time, dateadd(minute, datediff(minute, mb.progStartTime, mb.progEndTime), 0)) as timeDiff 
From    map22 as mp 
Inner   Join mba22 as mb 
        on  mp.ProgDate = mp.ProgDate 
        and mp.Channel= mb.Channel 
        and mp.Product= mb.Product
Where   mp.ProgDate = mb.ProgDate
And     Convert(DateTime,ProgDate) + Convert(DateTime,AdvTime)
            Between 
            Case 
            When ProgEndTime < ProdStartTime And DateDiff(hh,ProgEndTime,ProgStartTime) > 23 Then DateAdd(mi,-5,Convert(DateTime,[Date]) + Convert(DateTime,ProgStartTime))
            When ProgEndTime > ProdStartTime And DateDiff(hh,ProgStartTime,ProgEndTime) > 1 Then DateAdd(mi,-5,Convert(DateTime,[Date]) + Convert(DateTime,ProgStartTime)) 
            Else Convert(DateTime,[Date]) + Convert(DateTime,ProgStartTime) End
            And 
            Case 
            When ProgEndTime < ProdStartTime And DateDiff(hh,ProgEndTime,ProgStartTime) > 23 Then DateAdd(mi,5,Convert(DateTime,Case When ProgEndTime < ProdStartTime Then DateAdd(dd,1,[Date]) Else [Date] End) + Convert(DateTime,ProgEndTime))  
            When ProgEndTime > ProdStartTime And DateDiff(hh,ProgStartTime,ProgEndTime) > 1 Then DateAdd(mi,5,Convert(DateTime,Case When ProgEndTime < ProdStartTime Then DateAdd(dd,1,[Date]) Else [Date] End) + Convert(DateTime,ProgEndTime))  
            Else (Case When ProgEndTime < ProdStartTime Then DateAdd(dd,1,Convert(DateTime,[Date])) Else Convert(DateTime,[Date]) End) + Convert(DateTime,ProgEndTime) End
Order By mp.Id Asc
