Event and Procedure

Define Procedure:
delimiter $$
create procedure sp_test() 
BEGIN
    insert into tb_test values(null);
END
$$
delimiter ;

Adjust Event:
create event ev_test
on schedule every 5 second
do call sp_test();

/* 查看事情是否发生 */
select * from tb_test;

/* 确保事件启动 */
set global event_scheduler=1; 
alter event ev_test on completion preserve enable;

/* 清理工作 */
drop procedure sp_test;
drop event ev_test;
