mysql事件的開啟和調用教程

1、檢測事件是否開啟

show variables like 'event_scheduler';

2.開啟事件

set global event_scheduler = on;

3.創建一個存儲過程

delimiter //
create procedure test()
begin
update project set create_time = now();
end;

4.創建一個事件

create event if not exists e_test
on schedule every 30 second
on completion preserve
do call test();

5.關閉或開啟執行事件

alter event event_name on completion preserver [enable | disable]

6.刪除事件

drop event event_name;
