复制代码代码如下:

Rem==上一篇==
Rem================================================================
Rem= 参数说明:
Rem= pid当前ID,prame:栏目前辍(如一般web_news表,字段时一般为wn_**,prame就代表wn)
Rem= ptable(表前辍.如一般表名是:站点名_表名(shenzhe_news) ptable:就代表shenzhe)
Rem= 说明:采用上面命名法,可使该过程达到通用
Rem=============================================================

Function GetPre(pid,prame,ptable)
    id = prame&"_id"
title = prame&"_title"
table = "city_"&ptable
url = "show_"&ptable
sql = "Select TOP 1 "&id&","&title&" FROM "&table&" Where "&id&"<"&pid&" orDER BY "&id&" DESC"
set rs = Conn.Execute(sql)
If rs.eof or rs.bof Then
     pre = "上一篇:没有新闻了"
Else
     pre = "<a href="&url&".asp?"&id&"="&rs(0)&">"&rs(1)&"</a>"
End If
GetPre = pre
End Function

Rem = 下一篇
Rem=============
Rem= 参数函意和上过程一样
Rem==========
Function GetNext(nid,nrame,ntable)
    id = nrame&"_id"
title = nrame&"_title"
table = "city_"&ntable
url = "show_"&ntable
sql = "Select TOP 1 "&id&","&title&" FROM "&table&" Where "&id&">"&nid&" orDER BY "&id&" "
set rs = Conn.Execute(sql)
If rs.eof or rs.bof Then
     nnext = "下一篇:没有新闻了"
Else
     nnext = "<a href="&url&".asp?"&id&"="&rs(0)&">下一篇:"&rs(1)&"</a>"
End If
GetNext = nnext
End Function

实现代码:
偶数据库里有表:
city_active  city_date  city_note
city_active主要字段有: ca_id,cd_title
city_date主要字段有: cd_id,cd_title
city_note主要字段有: cn_id, cn_title

这样引用就可:
在show_note.asp?cn_id=4里引用上一篇下一篇
<%=GetPre(cn_id,"cn","note")%> ' 上一篇
<%=GetNext(cn_id,"cn","note")%> ' 下一篇
