php 处置每天几十万 近百万的 update 语句
php 处理每天几十万 近百万的 update 语句
php 处理每天几十万 近百万的 insert, update 语句 insert占少量 update 占绝大部分操作
大体上是 ,有一个页面 接受id和值 然后进行update操作 操作很简单 就是量大
个人用墨迹数据测试了一下 速度灰常之慢
请问谁有什么好的方法吗 (MySQL)
------解决方案--------------------
确认条件语句涉及的字段上有索引
如果不要求很强的实时性可以
使用LOW_PRIORITY关键词，则UPDATE的执行被延迟了，直到没有其它的客户端从表中读取为止。
------解决方案--------------------
win2003…………
你的mysql版本是不是有点老了…………
另外mysql在linux下的效率比在win的效率是数量级的提升……
------解决方案--------------------
这个和数据库管理系统有关，与PHP或ASP关系不大。asp如果使用mysql应该和php会差不多。
关于优化可以参考mysql的手册
