How to automatically change a value in MySQL - mysql

Question

I'm working on a system for payments for a school and I need to automatically add a new monthly debt for students, related to the month price. I was thinking about using scheduled events but it hasn't worked when I'm testing.
Please could anyone tell me if this is a good approach or give me any piece of advice for another approach? Thanks in advance.
This is what I was testing but it seems that it's not running since there's no new value on the debts table.
delimiter $$
create definer=`root`#`localhost` event registrar_mensualidad
on schedule every 5 second
on completion preserve
enable
do
begin
insert into debts(auto, amount, student_id, institution_payment_reason_id)
values (1, 100, 1, 1);
end;$$
I checked if the events_scheduler is enabled and it is in fact.
The system is being developed with laravel connected to a mysql database.

You might consider cron jobs.
CRONTAB (at every 1st day of the month)
#: sudo nano /etc/crontab
0 0 1 * * root php /var/www/html/your_php_query.php > output.txt
PHP
$qry = "insert into debts(auto, amount, student_id, institution_payment_reason_id)
values (1, 100, 1, 1);"
return $con->query($qry);
LOG
ouput.txt
1 // if insert is true
Or Laravel
App\Console\Kernel
<?php
namespace App\Console;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;
use Illuminate\Support\Facades\DB;
class Kernel extends ConsoleKernel
{
/**
* Define the application's command schedule.
*
* #param \Illuminate\Console\Scheduling\Schedule $schedule
* #return void
*/
protected function schedule(Schedule $schedule)
{
.........
// add this
$schedule->call(function () {
DB::insert('insert into debts(auto, amount, student_id, institution_payment_reason_id) values (?, ?, ?, ?)', [1, 100, 1, 1]);
})->monthly();
}
}
To check/validate the schedule, type: php artisan schedule:list
