How to Automate Deleting MySQL Rows Based on Date Comparison?

Automating MySQL Row Deletion Based on Date Comparison

Your request involves purging database rows where a "Date" field indicates a past date. To achieve this, you can utilize a PHP script alongside a cron job.

MySQL Query:

The PHP script will execute the following MySQL query:

<code class="php">mysql_query("DELETE FROM your_table_name WHERE Date < NOW()");
Copy after login

This query selects and deletes rows from the specified table ("your_table_name") where the "Date" values are earlier than the current date.

PHP Script:

<code class="php"><?php
include 'your_db_connection';
mysql_query("DELETE FROM your_table_name WHERE Date < NOW()");
?></code>
Copy after login
  • Create a PHP file containing this script and save it as "cronjobcommand.php".
  • Replace "your_db_connection" with the code necessary to establish the connection to your MySQL database.

Cron Job Setup:

In your control panel (e.g., cPanel), set up a cron job that executes "cronjobcommand.php" at the desired time, such as midnight.

This automated process will periodically clear out outdated rows from your database, ensuring they meet the date-based criteria you have specified.
