Question

How would I display rows that have a timestamp value within the last hour?

Here is what I have right now, and it is showing the latest rows, and only 3 rows because of the LIMIT.

$query5= mysql_query("SELECT * FROM  `made_orders` ORDER by id DESC LIMIT 0,3");



    WHILE($datarows5 = mysql_fetch_array($query5)):

    $name4 = $datarows5['Name'];
    $phone4 = $datarows5['Phone'];
    $entree4 = $datarows5['Entree'];
    $side14 = $datarows5['Side 1'];
    $side24 = $datarows5['Side 2'];
    $drink4 = $datarows5['Drink'];
    $totalcost4 = $datarows5['Total Cost'];
    $ip4 = $datarows5['Ip'];
    $id4 = $datarows5['id'];
    $time4 = $datarows5['timestamp'];

    echo "<iframe src=\"creatmeal-data.php?id={$id4}\" width=\"430px\" style=\"border:0px\" height=\"350px\"/></iframe>";

endwhile; ?>

In my above code, each time a row is found, it echos an iframe. How would I edit the query to use my timestamp column to show only the latest within an hour.

Thanks in advance for your help!

Answer 1

Your current query gets the three most recent orders regardless of whether or not they were created in the last hour.

Use this solution:

SELECT *
FROM made_orders
WHERE timestamp >= NOW() - INTERVAL 1 HOUR
ORDER BY timestamp DESC
LIMIT 3

This would get at most three orders within the last hour. If there was only one order within the last hour, it would only select one row.
