MySQL, result bigger than X number

Question

I'm trying to get the results of the past 15 days in a database. The time is added in epoch format, like 1400904415 .

I'm trying to get only the last results (15 days), so I'm wondering if it is possible to do something like this:

SELECT * FROM dataadded WHERE createdate="here something like createdate its bigger than currentdate - 15 days"

Is that possible?

Answer 1

使用DATE_SUB（SUBDATE）

SELECT * FROM dataadded WHERE createdate >= DATE_SUB(CURDATE(), INTERVAL 15 DAY);

Answer 2

You can also do this in PHP if you don't want to offload the work to your database

 $date = time() - (86400 * 15); //86400 seconds = 1 day
 $sql = 'SELECT * FROM dataadded WHERE createdate=' . $date;
