mysql：获取两个日期时间之间的记录计数 [英] mysql: get record count between two date-time

问题描述

我遇到了一个问题在MySQL。我想获取两个日期时间条目之间的记录计数。

例如：

在我的表中有一个名为created的列，其中包含 datetime 数据类型。

I am stuck with a problem in MySQL. I want to get the count of records between two date-time entries.
For example:
I have a column in my table named 'created' having the datetime data type.

我要计算在今天上午4:30和当前日期之间创建日期 - 时间的记录TIME。

I want to count records which were created date-time between "TODAY'S 4:30 AM" and "CURRENT DATE TIME".

我尝试了一些MySQL的功能，但仍然没有运气。

I tried some of MySQL's functions but still no luck with it.

我这个？
感谢。

Can you please help me with this? thanks.

推荐答案

可能是：

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 06:42:50';

或在之间使用：

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 06:42:50';

您可以根据需要更改日期时间。可以使用 curdate（）或 now（）来获取所需的日期。

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.
