First of all, let me explain the database. There are eight fields that need to be search: last name, city, state, zipcode are four that the user will enter a value in. Four more fields are simple text fields with yes/no entered.I'm trying to figure out the logic of the statement I'm going to use but wind up with no results each time I test it, so something's not right.
The search page has the four field that a user can enter parameters in the text box. There are also four checkbox the user can check. Example:
Enter last name
Enter City
Select State
Enter Zip Code
Check if FieldValue1 is Y
Check if FieldValue2 is Y
Check if FieldValue3 is Y
Check if FieldValue4 is Y
I want to be able to use this to search the database and display the results according to the following parameters:
All of the first four criteria are met but the field can be left blank AND the results are filtered by whther the FieldValues have "Y" in the fields.
So I want to be able to search for someone named Smith in Texas that has FieldValue1 checked. I also want to be able to search for everyone in Colorado that has FieldValue1 and FieldValue2 checked.
With me so far?
Here is the SQL statement I developed in Dreamweaver that doesn't work. It returns no results and is located on the results page.
<pre id=code><font face=courier size=2 id=code><%
Dim vols__lif
vols__lif = "1"
If (Request.Form("life"


vols__lif = Request.Form("life"

End If
%>
<%
Dim vols__edu
vols__edu = "1"
If (Request.Form("education"


vols__edu = Request.Form("education"

End If
%>
<%
Dim vols__fai
vols__fai = "1"
If (Request.Form("faith"


vols__fai = Request.Form("faith"

End If
%>
<%
Dim vols__fam
vols__fam = "1"
If (Request.Form("family"


vols__fam = Request.Form("family"

End If
%>
<%
Dim vols__lname
vols__lname = "1"
If (Request.Form("lname"


vols__lname = Request.Form("lname"

End If
%>
<%
Dim vols__city
vols__city = "1"
If (Request.Form("city"


vols__city = Request.Form("city"

End If
%>
<%
Dim vols__state
vols__state = "1"
If (Request.Form("state"


vols__state = Request.Form("state"

End If
%>
<%
Dim vols__zip
vols__zip = "1"
If (Request.Form("zip"


vols__zip = Request.Form("zip"

End If
%>
<%
Dim vols
Dim vols_numRows
Set vols = Server.CreateObject("ADODB.Recordset"

vols.ActiveConnection = MM_vol_STRING
vols.Source = "SELECT * FROM voldata WHERE (life = '" + Replace(vols__lif, "'", "''"








vols.CursorType = 0
vols.CursorLocation = 2
vols.LockType = 1
vols.Open()
vols_numRows = 0
%> </font id=code></pre id=code>
Anyone can point our where I'm going wrong here?

Seems like you making it more complicated than need.
1. Create a table with all the states names and a table with all four fields.
2. Create a search page with a text box for the name, a text box for the state, a drop down box binded to the States table, and a text box for the zip code.
3. Create a results page with all for fields. Next in your query just have """where state = textbox 1 or name = textbox 2 or zip = textbox 3 or city = text box 4""" This will give you results in from all 4 or from 3 or 2 or 1 fields depending what the user enters.
PS: dont forget to put a % as a value in the drop down box so the user can select all states.
