Is there a way to retrieve items from a database that are more than 12 hours old? I'm using a timestamp column to keep track of time, but I only require information based on hours and not year, month, or day.
I've tried the following query, but it's not working as expected (there are no errors, it just retrieves all data from the table).
$sql = "SELECT *FROM Y WHERE X and time > now() - INTERVAL 12 HOUR";
Your input is appreciated, Salman A. Thank you.
Give this a shot:
RETRIEVE * FROM Y WHERE X and TIMESTAMP(time) < (NOW() - INTERVAL 12 HOUR)
Make sure to use < instead of > since you're looking for entries more than 12 hours old.
