Question

Can anyone give me syntax to alter an event which has been already created

Here i have created an event with the following syntax

create event _insert on schedule at '2012-10-08 17:09' + interval 10 second do insert into event_test values(now());

and now i want to change the interval time from 10 seconds to 1minute

Here is the table creation syntax for event_test table

DROP TABLE IF EXISTS `testing`.`event_test`;CREATE TABLE  `testing`.`event_test` (`current_date_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`current_date_time`)) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Answer 1

Just a simple alter command ?

ALTER event _insert 
   ON SCHEDULE AT '2012-10-08 17:09' + INTERVAL 1 MINUTE -- or new date 
   DO INSERT INTO event_test VALUES(now());
