MySQL中的2個日期字段之間存在檢查給定日期

Question

我有包含2個日期字段的表。像：

id  from    to 
---  ----    -- 
1  2012-01-01  2012-01-05 
2  2012-01-04  2012-01-10 
3  2012-01-03  2012-01-07 

我想用一個日期（如：2012-01-06）來檢查日期是任何日期間（從，到）表中。

對於這種情況，我想獲得id - 2,3。我怎樣才能做到這一點？

Answer 1

SELECT * FROM table WHERE "2012-01-06" BETWEEN `from` and `to` 

或者

SELECT * FROM table WHERE `from` <= "2012-01-06" AND "2012-01-06" <= `to`

Answer 2

select id 
from myTable 
where `from` <= '2012-01-06' and `to` >= '2012-01-06' 

Answer 3

select * from Table where `from` < '2012-01-06' and `to` > '2012-01-06' 

Answer 4

如果列類型是date應用此條件。

WHERE '2012-01-06' BETWEEN `from` AND `to`
