Question

我正在尝试查询记录。日期存储为日期时间戳，我的查询如下所示：

SELECT    count(c.id) as totalOrders
FROM      Cart c
WHERE     c.artist_id = 1
AND       c.paid = 1
AND       date_format(c.created, 'Y-m-d') between '2016-09-06' AND '2016-09-07'

我的日期时间戳是这样的：2016-09-07 21:04:46

出于某种原因，这不会返回任何记录，为什么？

Answer 1

更改以下行：

html
  head
    title Registration Form
  body
ul
each post in posts
    form(action='', method='POST')
      label(for='post[email]') Email:
      input(type='text', name="post[_id]", value=post._id)
      br
      label(for='post[name]') Name:
      input(type='text', name="post[name]", value=post.name)
      br
      label(for='post[age]') Age:
      input(type='text', name="post[age]", value=post.age)
      br
      input(type='submit')

到

AND date_format(c.created, 'Y-m-d') between '2016-09-06' AND '2016-09-07'

date（）函数将从datetime返回日期，并将检查给定范围。

Answer 2

使用date（）函数代替date_format（）

SELECT    count(c.id) as totalOrders
    FROM      Cart c
    WHERE     c.artist_id = 1
    AND       c.paid = 1
    AND       date(c.created) between '2016-09-06' AND '2016-09-07'

PHP＆amp; MySQL查询日期之间的时间戳
