私は次のようなテーブル構造を持っています

ATM         Ticket Open Time    Ticket Closed Time

M30G324202  17-02-2013 06:15    19-02-2013 20:54
M30G324202  28-02-2013 21:00    01-03-2013 11:18
M30G324203  27-02-2013 19:10    28-02-2013 07:14
M30G324203  28-02-2013 07:15    28-02-2013 11:18

チケットのオープン時刻またはチケットのクローズ時刻が「20:00:00」と「06:00:00」の間、つまり午後 8 時と午前 6 時の間にある場合、その時間枠を持たない新しい行が作成されます。

例：上記の表の最初の行

ATM         Ticket Open Time    Ticket Closed Time

M30G324202  17-02-2013 06:15    17-02-2013 20:00
M30G324202  18-02-2013 06:00    18-02-2013 20:00
M30G324202  19-02-2013 06:00    19-02-2013 20:00

//Above was for Only 1st Row

//Second Row Change AS Follows

M30G324202  01-03-2013 06:00    01-03-2013 11:18 
   (Time From 28-02-2013 21:00 Will get neglected till next day morning 6 AM 
    as it is after 8 PM )

//Third Row Change AS Follows

M30G324203  27-02-2013 19:10    27-02-2013 20:00
M30G324203  28-02-2013 06:00    28-02-2013 07:14

//Fourth Row Change AS Follows

M30G324203  28-02-2013 07:15    28-02-2013 11:18 (No Change as it is)

54分なので20:00代わりに書きました。20:542 月 19 日の午後 8 時以降です。

素晴らしい質問です。 私の試みをチェックしてください：

declare @tbl as table (ATM nvarchar(20), TicketOpenTime datetime, TicketClosedTime datetime)
insert into @tbl values
('M30G324202', '02-17-2013 06:15', '02-19-2013 20:54'),
('M30G324202', '02-28-2013 21:00', '03-01-2013 11:18'),
('M30G324203', '02-27-2013 19:10', '02-28-2013 07:14'),
('M30G324203', '02-28-2013 07:15', '02-28-2013 11:18')

declare @min datetime, @max datetime
select @min = MIN(TicketOpenTime), @max = max(TicketClosedTime) from @tbl

;with T as(
    select CONVERT(datetime, convert(numeric(20), @min, 101)) dt
    union all
    select dt+1 from T where dt<@max
) 
select 
    a.ATM, 
    case when a.TicketOpenTime>dt1 then a.TicketOpenTime else dt1 end TicketOpenTime,
    case when a.TicketClosedTime>dt2 then dt2 else a.TicketClosedTime end TicketClosedTime
From @tbl a
cross apply(
    select 
        dt, 
        DATEADD(minute, 360, dt) dt1, 
        DATEADD(minute, 1200, dt) dt2 from T b 
    where 
        dt between CAST(a.TicketOpenTime as DATE) and cast(a.TicketClosedTime as DATE)
)x
where a.TicketOpenTime<=x.dt2
order by a.ATM, a. TicketOpenTime
