15万条数据的查询

szdhsoft 2011-05-08 09:44:40

数据库：mysql.
数据记录：158000条
对数据进行查询统计，统计费用字段，按时间段和区域进行横向统计。
查询的时候PHP页面显示超时。大概有一分钟的样子。
请问有没有更好的办法解决速度问题？？？？

优化数据库吧，最好把时间字段用时间戳保存，int做索引还是很快的！优化得当0.1秒内绝对能查询完成！

你自己可以用explain来看看sql语句的好坏

表documents中加一个trans_fee，start_station，end_station的联合索引

首先这句'select ID from start_station order by id asc' 把order by id asc去掉，数据库默认就是升序的，使用order by很难用到索引，并且速度慢很多

是SQL语句问题，像楼上所说。开始的查询并没有条件。等于15万的ID一起获得。

而且这个mysql_db_query在PHP4以后就不推荐使用了。你的代码里居然还在使用。用
mysql_select_db和mysql_query来代替它，具体用法百度找下。很简单的。

所有表的表结构，
你里面多个表，哪个的数据是15万？
其它表里数据多少？

查这种性能问题，最好是自己做测试，不要想当然，
查出具体哪一部分的速度太慢，再做优化，

1.检查一下硬盘
2.优化一下 MYSQL.INI
3.检查一下自己的SQL语句尽量不要使用 LIKE
