你好!我在14号哪天提到的“如何在MX定义两个以上的搜索?”你的回答,我还是无法完成。我把原代码写在下面你帮我看看要咋修改,能达到满足“城市,折扣,备注”三个条件同时搜索或只输入其中一个或两个条件也能显示满足条件的内容,谢谢!!!!


代码如下:

“如何定义两个以上如“城市,价钱,公司类型”同时搜索”
这是你的问题。
代码太长,不容易看,这样吧!我给你说地稍微详细点。
一、首先要用数据库,例如:
定义四个字段:
theid
thecity
theprice
companytype
二、查询页,search.asp
插入三个文本框,用于输入“城市,价钱,公司类型”三个关键字
value分别为:
thecity
theprice
company

form设为 GET action设为:result.asp
三、结果页,result.asp
需要根据search.asp传来的三个查询参数进行查询并显示结果。
首先要定义记录集rsresult
name:rsresult
connection:选择你的连接
table:选择数据表
columns:选all
filter:
sort:
点击右边advanced...按扭切换到高级模式
点击variables:中的加号
name | dafault value | run-time value分别如下:
vcity | % | Request.QueryString("thecity")
同样再添加两个:
vprice | % | Request.QueryString("theprice")
vtype | % | Request.QueryString("companytype")

在上方SQL中手写代码:
SELECT *
FROM tablename
WHERE thecity LIKE 'vcity' AND theprice LIKE 'vprice' AND company LIKE 'vtype'
点击OK
把相应的记录插入页面。

OK!
好累啊!

可能和你的程序不一样,不过思路和方法是一样的。另外多到网上找些类似教程看看。
