asp 多表查询

假设3个客户表为:

vip客户表: ID cName , addr , ...

长期客户表: ID cName , addr , ...

临时客户表: ID cName , addr , ...

假设相同字段有 id cName , addr

那么一条SQL就可以实现查询了:

select id , cName , addr from vip客户表 where cName like %张三%

union all

select id , cName , addr from 长期客户表 where cName like %张三%

union all

select id , cName , addr from 临时客户表 where cName like %张三%

显示结果:

ID cName Addr

寻求多条件站内搜索asp源码(250分)

楼主你好:

针对你的问题,我已经写好ASP代码,支持多条件查询和模糊查询,包括分页代码都写好了,100%能用!

注意:表中各字段名我暂时用的中文,就是你提到的:"标题、内容、发布者" ,为的是让你理解,但你实际应用中,最后不要将字段名设为中文,改成英文吧!

查询及显示查询结果的代码如下:

%

set conn=server.createobject("adodb.connection")

conn.open "driver={microsoft access driver (*.mdb)};dbq="server.mappath("数据库名.mdb")

%

%

sql88="select * from 数据表名 where "

if trim(request("bt"))"" then

sql88= sql88 "标题 like '%"trim(request("bt"))"%' and "

end if

if trim(request("nr"))"" then

sql88= sql88 "内容 like '%"trim(request("nr"))"%' and "

end if

if trim(request("fbz"))"" then

sql88= sql88 "发布者 like '%"trim(request("fbz"))"%' and "

end if

sql88= sql88 " 1=1 "

set rs88=server.createobject("adodb.recordset")

rs88.PageSize = 2 '这里设定每页显示的记录数

rs88.CursorLocation = 3

rs88.Open sql88,conn,0,2,1 '这里执行你查询SQL并获得结果记录集

pre = true

last = true

page = trim(Request.QueryString("page"))

if len(page) = 0 then

intpage = 1

pre = false

else

if cint(page) = 1 then

intpage = 1

pre = false

else

if cint(page) = rs88.PageCount then

intpage = rs88.PageCount

last = false

else

intpage = cint(page)

end if

end if

end if

if not rs88.eof then

rs88.AbsolutePage = intpage

end if

%

for i = 1 to rs88.PageCount

if i = intpage then%

end if

next

%

/select 页 /font

/td

/tr

/table

/form

%

rs88.close

set rs88=nothing

conn.close

set conn=nothing

请复制上面的代码,保存为:search.asp ,希望你能满意!!!

asp多表查询

这个好办!多层次查询,一个子集一个父集.打开两个数据表就行.

核心代码是这样的:

set rs=Server.CreateObject("ADODB.Recordset")

sql="select * from [file]"

rs.open sql,conn,1,2

set rs1=Server.CreateObject("ADODB.Recordset")

sql1="select * from [leibie] where [id]="rs("tit")

rs1.open sql1,conn,1,2

do while (not rs.EOF)

response.write(""rs("id")" "rs1("bid")" "rs("category")" "rs("come")" "rs("writer")" "rs("body")" "rs("visit")" "rs("time")"br/")

rs.movenext

loop

剩下的就自己去写了.
