Hi,

Instead of using a stored procedure, the best way will be to use a User Defined Function and catch the return value in the  recordset that will be passed to ASP page

Something like this (untested):
Dim cmd
Set cmd = Server.CreateObject("ADODB.Command")
With cmd
   .ActiveConnection = "your connection string goes here"
   .CommandText = "DoesRecordExist"
   .CommandType = adCmdStoredProc
   .Parameters.Append .CreateParameter("@RETURN_VALUE", adInteger, adParamReturnValue, 0)
   .Parameters.Append .CreateParameter("@pid", adInteger, adParamInput, 0,YourInputValueGoesHere)
   .Execute , , adExecuteNoRecords
   Response.Write .Parameters("@RETURN_VALUE").Value
End With
Set cmd = Nothing

Make sure you are including all the ADO constants (use adovbs.inc) or replace them with their corresponding values.

hi
Let me modify the stored procedure a bit.

CREATE PROCEDURE DoesRecordExist
   @pid int,
   @Return Smallint Output
AS

IF EXISTS(SELECT * FROM BasketItems WHERE ProductID = @pid)
  Select @RETURN = 1
ELSE
   Select @RETURN = 0
GO

Then the ASP code:

dim cmd, prmPid, prmReturn, pid
pid = request("pid")
Set cmd = Server.createobject("ADODB.Command")
With cmd
         Set .activeconnection = "Your Connection object's name"
         .commandType = "adcmdStoredProc"
         .CommandText = "DoesRecordExist"
         
         Set prmPID = .CreateParameter("@PID",adInteger, adParamInput,4,pid
          .Parameters.Append prmPID

         Set prmReturn= .CreateParameter("@Return",adSmallint, adParamOutput,2)
          .Parameters.Append prmReturn

          .Execute

          Response.write .Parameters("@Return").Value
End With

I think this would work
Bye
