How do I reset a MySQL column in a table every year? - mysql

Question

I have a column named lv_casual in a table called tbl_employees. I need to reset the column to 0 at a specific date every year.

Answer 1

You can use MySQL event schedule. Providing an example below.
You have to enable the schedular first
SET GLOBAL event_scheduler = ON;
Then create the event
CREATE EVENT your_event_name
ON SCHEDULE EVERY 1 YEAR
STARTS '2021-10-12 00:00:00'
DO
UPDATE table SET column=0;
Check MySQL document for creating event

Answer 2

You can use a cron job to run once per year at end of the year, create a script that will reset all the records on that column to 0.
/usr/local/bin/ea-php99 /home2/accounname/https://example.com/cron_execute_file
okay bro this how your execute file should look like cron_execute_file.php
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";
// Create connection to db
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "UPDATE employees SET leaves='12' WHERE leaves >= 0";
if ($conn->query($sql) === TRUE) {
echo "Record updated successfully";
} else {
echo "Error updating record: " . $conn->error;
}
$conn->close();
?>
