mysql:获取两个日期时间之间的记录数
我在 MySQL 中遇到了问题.我想获取两个日期时间条目之间的记录数.
例如:
我的表中有一个名为created"的列,它具有 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.
我想计算在TODAY'S 4:30 AM"和CURRENT DATE TIME"之间创建日期时间的记录.
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,但仍然没有成功.
I tried some of MySQL's functions but still no luck with it.
你能帮我解决这个问题吗?谢谢.
Can you please help me with this? thanks.
推荐答案
可能与:
SELECT count(*) FROM `table`
where
created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';
或使用 between
:
SELECT count(*) FROM `table`
where
created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';
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.
