查看event是否开启

show variables like '%sche%';

将事件计划开户

set global event_scheduler =1;

创建存储过程test

CREATE PROCEDURE test ()
BEGIN
update examinfo SET endtime = now() WHERE id = 14;
END;

创建event e_test

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

每隔30秒将执行存储过程test,将当前时间更新到examinfo表中id=14的记录的endtime字段中去.

关闭事件任务

alter event e_test ON
COMPLETION PRESERVE DISABLE;

开户事件任务

alter event e_test ON
COMPLETION PRESERVE ENABLE;
