Hi, this is very simple...

I am trying to find out if an IP address (that was saved in a table) is in a particular column called IP and if that is so...return a result

I just need the SQL to get it done

ADO connection here to whatever .mdb

i need the sql to determine whether or not the value is in the table or not...or at least how to find out ... evaluate and send a result bsed on that

i will take the result and then redirect all IP's in the list to a page prohibiting them from entering the site...

basically i just need a snipplet of how to check if the IP in already in the DB or not

Looking for something like this?
'Datebase connection

set oConn=Server.CreateObject("ADODB.Connection")

oConn.Provider="Microsoft.Jet.OLEDB.4.0"

oConn.Open "Database.mdb" 'CHANGE DATABASE NAME!

set oRS = Server.CreateObject("ADODB.recordset")

sql="SELECT IP FROM Table1" 'CHANGE TABLE NAME!

oRS.Open sql, oConn
 

If oRS.EOF Then

	'IP Not Found!

Else

	Response.Redirect("http://www.google.com/")

End If
 

'Cleanup

oRS = Nothing

oConn = Nothing

oRS.Close

oConn.Close

dim rs as recordset
set rs =currentdb.openRecordset("SELECT * FROM IP WHERE IP_COLUMN = ' " & sIPVariable & " ' "
if rs.eof then
'not in table
else
'in table
end if

DarrenMcCall,
- There is no condition in your query, so it will just check if there is anything in the table or not.
- If you do a redirect before the cleanup, the cleanup will not run.
- In the cleanup, you have to call Close before you set the references to Nothing.

This will work a little bit better:
' Declare variables

Dim objConnection, objRS, lngCnt, strIP

' Get IP

strIP = Request.ServerVariables("REMOTE_ADDR")

' Open connection

Set objConnection = Server.CreateObject("ADODB.Connection")

objConnection.Provider = "Microsoft.Jet.OLEDB.4.0"

objConnection.Open "Database.mdb"

' Count occurances of the IP

strSQL="select count(*) from Blocked where IP = '" & Replace(strIP, "'","''") & "'"

Set objRS = objConnection.Execute(strSQL)

' Get the result

lngCnt = objRS(0)

' Close the recordset

objRS.Close

Set objRS = Nothing

' Close connection

objConnection.Close

Set objConnection = Nothing

' Check result

If lngCnt = 0 Then

        'IP Not Found

Else

        Response.Redirect "Denied.asp"

End If

this is the snipplet of code that I developed to achieve this task.  
Dim adoCon, ID, rsGuestbook, strSQL, banIP

Set adoCon = Server.CreateObject("ADODB.Connection")

adoCon.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("guestbook_2003.mdb")

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

strSQL = "SELECT Banned.IP FROM Banned WHERE IP='" & Request.ServerVariables("REMOTE_ADDR") & "'"

rsGuestbook.Open strSQL, adoCon
 

Do While not rsGuestbook.EOF

	banIP = rsGuestbook("IP")

	if banIP <> "" then

	Response.Redirect "Denied.asp"

	end if

	rsGuestbook.MoveNext

loop
 

rsGuestbook.Close

Set rsGuestbook = Nothing

Set adoCon = Nothing
