I have already posted a blog (Event Scheduler an alternative to cronjob) with different advantages of Even scheduler over cron job, here I am sharing how you can configure MySql server to enable or disable scheduler and writing a sample event scheduler.
You can check with below query as your server is up for event scheduler or not.
Query will gives your "ON" or "OFF". if it is off you can enable it as:
SET GLOBAL event_scheduler = ON;
Now you can create your own event scheduler as below:
CREATE EVENT suresh_test
EVERY 10 SECOND
INSERT INTO test_scheduler (`datetime`) VALUES (CURRENT_TIMESTAMP);
The above scheduler will runs every 10 second and insert a row in "test_scheduler" table.
