Question

Question: anyone have multiple searching coding using asp ? Can you share?

This is what I want to do..

There are 3 option or searching..by name, by location, by region

For the first display all data with paging..on top it has searching.

<textfield>name</textfield><list/menu>location</list/menu><list/menu>region</list/menu>

when search by region it will display all region are selected. Then it allow to filter by name to get specific

 <%
   Dim adoCon        
   Dim rsGuestbook    
   Dim strSQL          
   Dim lngRecordNo    

   lngRecordNo = CLng(Request.QueryString("ID"))

   Set rsGuestbook = Server.CreateObject("ADODB.Recordset")

   'Initialise the strSQL variable with an SQL statement to query the database'
   strSQL = "SELECT * FROM tbl_Master WHERE ID=" & lngRecordNo

   rsGuestbook.Open strSQL, oConn
%>

Answer 1

Here is a querystring search be name,department,age. It works properly. It might help you. Just fetch your values. Put those in proper places. And don't forget to change your tablename

    name1=request.QueryString("name")
    dept1=request.QueryString("dept")
    age1=request.QueryString("age")

sqlStr="Select * from Student_Entry"
    sqlWhere=""

    if name1<>"" then
        sqlWhere = " Where S_name='"&name1&"'"  
    end if
    if dept1<>"" then
        if sqlWhere = "" then
            sqlWhere = " Where S_dept='"&dept1&"'"
        else
        sqlWhere = sqlWhere&" And S_dept='"&dept1&"'"
        end if  
    end if

    if age1<>"" then
        if sqlWhere = "" then
            'sqlWhere = " Where  S_age="&age1&""
            sqlWhere = " Where  S_age"&agestr&age1 

        else
            'sqlWhere = sqlWhere&" And  S_age="&age1&""
            sqlWhere =sqlWhere&" And S_age"&agestr&age1
        end if  
    end if

    sqlStr = sqlStr & sqlWhere

Answer 2

it sounds like you are describing multiple dependent lists (?)

there is an example here with demo:

Answer 3

strname , strlocation and strregion value will depend on selection if not select then default value will be "". 

strSQL = "SELECT * FROM tbl_Master WHERE ID=" & lngRecordNo 

if strname <> "" THEN
strSQL = strSQL & " and name ='"& strname &"' "
END IF 

if strlocation <> "" THEN
strSQL = strSQL & " and location='"& strlocation &"'
END IF 

if strregion <> "" THEN
strSQL = strSQL & " and region='"& strregion &"'
END IF

rsGuestbook.Open strSQL, oConn
