查看event是否开启: show variables like '%sche%';

将事件计划开启: set global event_scheduler=1;

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;

简单实例.

创建表 CREATE TABLE test(endtime DATETIME);

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.

使用navicat UI界面操作更方便，存储过程(函数)和计划任务(事件)

mysql中查看Event作业情况

通过执行如下的语句：

SELECT * FROM information_schema.EVENTS

实用性语句

SELECT LAST_EXECUTED FROM information_schema.EVENTS WHERE EVENT_NAME='reset_score';

自动开启

在my.ini的[mysqld]下

event_scheduler=ON
