  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;
