sql-server-2008 - SQL Server 查询日期

Question

我有这张桌子Table1：

Room - StartDate - EndDate
1    - 01/01/2013  05/01/2013
1    - 14/01/2013  15/01/2013
2    - 10/01/2013  13/01/2013

我想显示从 2013 年 2 月 1 日到 2013 年 3 月 1 日所有可用的“房间”

我用：

select * 
from Table1 
where ('02/01/2013' NOT BETWEEN table1.stardate AND table1.enddate) 
   OR ('03/01/2013' NOT BETWEEN table1.startdate AND table1.enddate)

但是查询结果显示2（这是正确的）但也显示1，因为最后一条记录。

我该怎么做才能只显示“房间 2”？

谢谢

Answer 1

我想你已经有另一张桌子了Rooms。

所以，如果Table1是一个Reservations表：

SELECT  r.* 
FROM    Rooms AS r
WHERE   NOT EXISTS
        ( SELECT    *
          FROM      Table1 AS res
          WHERE     res.Room = rooms.RoomID
            AND     '20120102' < res.EndDate 
            AND     res.StartDate < '20120103' 
        ) ;

Answer 2

如果 enddate 始终 > startdate，则更OR改为AND

select * 
from   Table1
where  ('02/01/2013' NOT BETWEEN table1.startdate AND table1.enddate)
AND    ('03/01/2013' NOT BETWEEN table1.startdate AND table1.enddate)

Answer 3

尝试这个

Select * from Table1 

where(stardate >='02/01/2013' and enddate <= '03/01/2013')
