能否让数据库每天0点自动重置某个字段
设计一个酒店预订类的网站后台，某一种特价房每天只卖5间，如何让数据库中这种房间的数量roomNum这个字段在每天某一时刻自动重置为5？MYSQL有这样的功能吗？还是写一段代码来插入roomNum这个字段，实现每天更新5间这样的功能呢？

mysql从5.1.6开始新增一个 事件(Event)的东西貌似可以满足你的需求
但不建议你这样做，第一配置较复杂，第二维护起来很麻烦。
既然是网站后台完全自己写一个定时任务每日去重置字段就可以啦
SpringFramework里面自带的qurtz可以很方便的执行定时任务
什么你说你用的是PHP，当我没说好了
谁说 php 就不行了? cron 一样好用. 不许鄙视 世界上最好的语言 :)
应该有订房记录吧 只需要查询当天记录中某种特价房已经被订购的数量就行了
