endtime datetime,
primary key(id)
);

3 插入数据:

insert into examinfo values('1','2011-4-23 23:26:50');

CREATE PROCEDURE test ()
BEGIN
update examinfo SET endtime = now() WHERE id = 1;
END;

on completion preserve
do call test();

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;
