mysql怎么让一个存储过程定时执行

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

首先来看一个简单的例子来演示每秒插入一条记录到数据表

USE test;

CREATE TABLE aaa (timeline TIMESTAMP);

CREATE EVENT e_test_insert

ON SCHEDULE EVERY 1 SECOND

DO INSERT INTO test.aaa VALUES (CURRENT_TIMESTAMP);

等待3秒钟后&#
