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 MBA 表中的StartTime&之间。EndTime

但是当持续时间（ProgStartTime- ProgEndTime）为一小时时，我需要 + 或 - 5 分钟的缓冲区。

我 00:05:08 to match 23:00:00需要，02:00:00并且 。20:57:16 to match 21:00:0022:00:00

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
