Question

I’m relatively a newbie, would appreciate help 🙂

I am looking to find entry(ies) from a mysql table which were created some time between now and a certain timestamp in the past. This time in the past is stored in a variable (say $timeinthepast, a few hours ago or yesterday, whatever). And the column ‘timecreated’ in the table is the timestamp of the creation of entry.

Would the following work? If not, what would?

Thanks!

    <?php

        $query = mysql_query("SELECT * FROM table1 
                 WHERE timecreated = DATE_ADD(NOW(), INTERVAL -$timeinthepast)");

    ?>

I am basing this on: Query to select records from a database that were created within the last 24 hours

Answer 1

As long as $timeinthepast is valid (1 MONTH, 2 HOUR, e.g.) in the sql you can try BETWEEN

$query = mysql_query("SELECT * FROM table1 
         WHERE timecreated BETWEEN 
         DATE_SUB(NOW(), INTERVAL $timeinthepast) AND NOW()");
