 The MySQL Event Scheduler manages the scheduling and execution of events.

If you are running larg number of data like Shopping Cart, Any Portals that time we need to handle data.

CREATE TABLE user
(
user_id INT  AUTO_INCREMENT,
user varchar(250),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (user_id)
) ;

Start phpmyadmin

SET GLOBAL event_scheduler = ON;

Creat New Event

CREATE EVENT newEvent
ON SCHEDULE EVERY 1 DAY
DO
DELETE FROM user WHERE created_at = DATE_SUB(NOW(), INTERVAL 10 DAY);
