如果用户选择2014-02-10和2014-02-08，则日期有两个选择选项。它将显示这两个日期之间的日期

我知道这个查询，但这不像我想要的那样工作，因为如果用户选择第一个日期然后第二个日期，那么我的查询将不会像我想要的那样出现

select * from mdx
  where mdx_timestamp >= '2014-02-10' and mdx_timestamp <= '2014-02-08'

如果有任何解决方案可以找到两个日期之间的日期，而日期来自db

Answer 1

使用Between条款

select * from mdx where mdx_timestamp between '2014-02-08' and '2014-02-10'

Answer 2

可能是您的查询应该像

select * from mdx where mdx_timestamp <= '2014-02-10' and mdx_timestamp >= '2014-02-08'

逻辑上没有大于2014-02-10且小于2014-02-08的日期。您需要反向执行

Answer 3

使用between子句：

select * from mdx where mdx_timestamp between '2014-02-08' and '2014-02-10'

或者：

select * from mdx 
  where mdx_timestamp between 
              least( '2014-02-08', '2014-02-10' )
              and
              greatest( '2014-02-08', '2014-02-10' )

请参阅 ：
MySQL: expr BETWEEN min AND max

Answer 4

我相信您必须将时间添加到日期，否则它将无法正常工作：

select * from mdx where mdx_timestamp >= '2014-02-10 00:00:00' and mdx_timestamp <= '2014-02-08  23:59:59'

Answer 5

“SELECT * FROM mdx WHERE mdx_timestamp＆gt; =”2014-02-08“AND mdx_timestamp＆lt; =”2014-02-10“;

两个日期之间的SQL查询
