检查MySQL中2个日期字段之间是否存在给定日期

Question

我的表包含2个日期字段。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

我想使用日期（例如：2012-01-06）来检查日期是否在表格中的任何日期（从，到）之间。

对于这种情况，我想获得id - 2,3。我怎么能这样做？

Answer 1

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

或

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

如果列类型为date，则应用此条件。

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

Answer 4

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