Question

我正在加入mysql中的表，但我有一个表保存日期的表：

table: cutoff

      date       roomid  
---------------------------  
    2012-11-03     25
    2012-11-04     25
    2012-11-05     25
    2012-11-06     25

这是我的SQL查询：

SELECT t.RoomId, t.USD, t.MXN, i.Image, a.RoomName, a.RoomDesc, cu.date FROM Tarifas AS t 
INNER JOIN Images AS i ON i.RoomId = t.RoomId
INNER JOIN Availability AS a ON a.RoomId = t.RoomId 
INNER JOIN cutoff AS cu ON cu.roomid = t.RoomId AND cu.date NOT BETWEEN '$from' and '$to' 
WHERE t.Start <= '$from' AND t.End >= '$from' ORDER BY USD

我想得到日期不在截止表中的所有行。但它给了我相反的意义！我不知道该怎么办，非常感谢任何帮助！

添加TARIFA表：

table: tarifas
RoomId      Start         End       USD       MXN
---------------------------------------------------
25        2012-11-01   2012-11-20   60.00    620.00
26        2012-11-01   2012-11-20   80.00    820.00
27        2012-11-01   2012-11-20   55.00    570.00

试试这个（已编辑）：

SELECT t.RoomId, t.USD, t.MXN, i.Image, a.RoomName, a.RoomDesc
FROM Tarifas AS t 
INNER JOIN Images AS i ON i.RoomId = t.RoomId
INNER JOIN Availability AS a ON a.RoomId = t.RoomId 
WHERE t.RoomID NOT IN
    (SELECT DISTINCT roomid FROM cutoff
    WHERE date BETWEEN '$from' AND '$to')
AND t.Start <= '$from' AND t.End >= '$from'
ORDER BY USD

连接表但不显示符合where子句的行
