  SELECT o.OrderID, o.OrderDate from Orders o, Customers c,
  
  WHERE o.CustomerID = c.CustomerID and c.CompanyName = ?
  
  Code:
  
  <%@ Language=VBScript %>

    adoConn.ConnectionString = sConn
  
    adoConn.CursorLocation = 3 'adUseClient
  
    adoConn.Open
  
    Dim adoCmd
  
    Set adoCmd = CreateObject("ADODB.Command")
