mysql：获取两个日期时间之间的记录计数

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()

now()
