10w条数据，查询变得极慢

[chaiuong]

一台独立服务器，1G内存

我该换服务器还是整理程序

[robur]

给楼主提一个问题……
我看你是这么写的：
rs.open "select * from shop_books where "&sql1&" order by adddate desc",conn,1,1

我以前做一套系统的时候，也是这么写的，但是同等规模的数据，SQL Server还建立了正确的索引，速度居然还不如Access快……

后来发现，应该用Conn.Execute(sql)，这样写，页面一刷而过……

理论上lz的方法不存在任何问题，但是理论往往tmd输给实践……

[飘零雾雨]

整理一下程序！

[ck1983]

还是先整理程序

[lihuasoft]

什么数据库?---还是先整理一下程序吧....服务器已经够好了

[seahi]

LZ没有创建索引吧？查询语句用的好不好也很重要。

[擒兽]

10w就慢了，估计是Access。

[chaiuong]

SQL2000，没有存储过程，我还不会

大家看一下我的程序先，写得很乱，大家帮我想个办法

[Mapleleaf123]

这多。看了头晕

[chenguang79]

眼花了

[greatbag]

10w条数据不算多
优化一下数据库
用好点的分页sql
看这里
http://blog.csdn.net/greatbag/archive/2006/09/11/1209227.aspx

[wtogether]

1、在WHERE *** ORDER BY ***需要的字段上建立索引
2、SQL Server 2000不要用ado自带的功能分页
这里有个说明
http://community.csdn.net/Expert/topic/4777/4777345.xml?temp=.5093958

[chaiuong]

我大概改了一下

在WHERE *** ORDER BY ***改成id,name了

速度还是没快多少

[xeonwell]

是啊，我P3 550+300多M的内存，10W也还好啊。，优化吧，多看看这方面文章，，先去搜索一番

[tomquan]

强烈建议用SQl存储过程

[chenda8851]

问问楼上的，存储过程在什么条件下才用
是在数据量多的时候才用吗

[minwent]

分页查看，一次性拿那么多也看不完。
