Update every 5 minutes a value – Phpmyadmin

I’m not aware about how to use PHPMyAdmin interface to create events, however, this can be done in “pure” SQL :

CREATE EVENT IF NOT EXISTS your_event_name
ON SCHEDULE EVERY 5 MINUTE
DO UPDATE table SET x=0;

About the part ON SCHEDULE EVERY 5 MINUTE, this will execute the event now, and then every 5 minutes, forever.

If you want to delay the execution, you can add STARTS after the EVERY statement :

-- This will delay the first execution in 1 hour
ON SCHEDULE EVERY 5 MINUTE STARTS CURRENT_TIMESTAMP + INTERVAL 1 HOUR

You can define when the EVENT should stop working using ENDS :

-- This will end the event in 1 week
ON SCHEDULE EVERY 5 MINUTE ENDS CURRENT_TIMESTAMP + INTERVAL 1 WEEK

Of course, you can combine both STARTS and ENDS

-- This will end the event in 1 week
ON SCHEDULE
    EVERY 5 MINUTE -- Play every 5 minutes
    STARTS CURRENT_TIMESTAMP + INTERVAL 1 HOUR -- Start in 1 hour
    ENDS CURRENT_TIMESTAMP + INTERVAL 1 WEEK -- End in 1 week

If you have more than 1 query to perform in the event, you need to wrap the instructions inside BEGIN / END :

DELIMITER $$

CREATE EVENT IF NOT EXISTS your_event_name
ON SCHEDULE EVERY 5 MINUTE
DO
    BEGIN
        UPDATE table1 SET x=0;
        UPDATE table2 SET foo='bar';
    END $$

DELIMITER ;
