关于搜索的有关问题 sql="select * from wzxx where title like '%"&title&"%' order by id desc"

关于搜索的问题 sql="select * from wzxx where title like '%"&title&"%' order by id desc"
下面是关于搜索的代码。其中 lbid 是类别。wzxx这个表里是题库表。里面全是题内容和答案。现在问题是。我想让搜索不但搜title的内容。也对content里的内容进行搜索。该如何修改呢。谢谢。

<%if lbid="" and title=""then
sql="select * from wzxx order by id desc"
end if

if lbid="" and title<>""then
sql="select * from wzxx where title like '%"&title&"%' order by id desc"
end if

if lbid<>"" and title=""then
sql="select * from wzxx where lbid="&lbid&" order by id desc"
end if

if lbid<>"" and title<>""then
sql="select * from wzxx where lbid="&lbid&" and title like '%"&title&"%' order by id desc"
end if
dim i,intPage,page,pre,last,filepath
set rs = server.CreateObject("adodb.recordset")
rs.PageSize = 28

rs.Open sql,conn,0,2,1
pre = true

end if

------解决方案--------------------

SQL code

select * from wzxx where lbid='"&lbid&"' and (title like '%"&title&"%' or [content] like '%"&title&"%') order by id desc
------解决方案--------------------
C# code
上面写错了// 试试这个，不过当数据量比较大的时候性能会有问题sql="select * from wzxx where charindex('" + title + "',title)>0 or charindex('" + title + "',content)>0 ";
------解决方案--------------------
select * from wzxx where lbid="&lbid&" and (title like '%"&title&"%' or [content] like '%"&title&"%') order by id desc
------解决方案--------------------
SQL code
select * from wzxx where  patindex('%'+參數+'%',[title])+ patindex('%'+參數+'%',[content])>0 order by ID desc
