mysql - 如何选择 2 小时前的值

Question

我对 mysql 查询没有太多了解..我正在尝试从现在起过去两个小时内从数据库中获取值..我已经搜索了它并且我也找到了一些相关的帖子..但不幸的是我我无法实现逻辑..请帮我解决这个问题..

这里是mysql查询

select * 
from `ordermaster` 
where ((
`ordermaster`.`Pick_date`
 = curdate())
 and (`ordermaster`.`Pick_time`
 <= (now() - interval 2 hour)) 
and (`ordermaster`.`Status` 
= 2))

其中，Pick_Date =“2017-04-19”(今天日期)和 Pick_Time =“10:00:00”(24 小时格式)

Answer 1

尝试以下操作:

Select * From ordermaster om
Where  Concat(om.Pick_date,' ', om.Pick_time) as date Between 
       (now() - interval 2 hour) and now()
       AND Status = 2
