Thanks, I will let you know how it works.

In the meantime, what would need to be adjusted in:

Dim FoxCMD As OleDbCommand = Library.SQLExecCommand("select shippers.companyname as shippername, orders.* " + _
 "from orders, shippers where orders.shipvia = shippers.shipperid and customerid = ?", oParams)

if I would have two parameters?

Let's assume that we would have a field PurchaseDate that we would like to have all orders after a certain date.
