How to make mysql run Delet query automatically

I Have an OTP table and I want to delete data that is older than 5 minutes automatically

Then how could I make trigger or procedure for that?

Answer

You must use according Event Scheduler procedure.

CREATE EVENT remove_old_rows
ON SCHEDULE
EVERY 10 SECOND
COMMENT 'Delete the rows that are older than 5 minutes from OTP table.'
DO
    DELETE 
    FROM OTP_database.OTP_table
    WHERE created_at < CURRENT_TIMESTAMP - INTERVAL 5 MINUTE;

Do not forget to enable Event Scheduler.
