两个值desc之间的SQL查询

Question

我有一个MySQL表,有两个字段start_interval,end_interval都存储int代表小时的值.我正在使用此查询从该表中选择记录:

SELECT *
FROM messages
WHERE 23 BETWEEN start_interval AND end_interval;

当start_interval大于end_interval？时,如何获取值？例如,如果start_interval = 22和end_interval = 5？

Answer 1

怎么样:

SELECT * FROM messages
WHERE 23 BETWEEN LEAST(start_interval, end_interval) AND
                GREATEST(start_interval, end_interval);
