评估mysql日期范围

Question

我有一个带有一些日期范围的mysql表，例如：

start: 2015-09-10 end: 2015-09-10

现在，我必须检查另一个日期范围是否在开始日期之内，即使只是几天。

1. 2015-09-02 - ＆gt; 2015-09-03超出范围;
2. 2015-09-05 - ＆gt; 2015-09-11在范围内;
3. 2015-09-11 - ＆gt; 2015-09-12在范围内;
4. ...

我有这些查询，适用于案例1和案例2：

SELECT * FROM prenotazione WHERE id_stanza=1 AND (start BETWEEN '2015-09-11' AND '2015-09-12' and end BETWEEN '2015-09-11' AND '2015-09-12' )

对于案例3，查询不返回任何结果，即使id为给定日期在范围内。 你能救我吗？

Answer 1

使用OR匹配开头或结尾

SELECT * FROM prenotazione 
WHERE id_stanza=1 AND
((`start` BETWEEN '2015-09-11' AND '2015-09-12') OR (`end` BETWEEN '2015-09-11' AND '2015-09-12'))
