Save the PDF file where? It would help if you were more clear in your requirements. An SQL connection would be required only if you wanted to save the file (or information about the file) in a database. If you want to save it
on the server, that's easy, although the full answer requires knowing how you acquired the PDF File. Uploaded from a user of your site, using the file upload control? Created by you on the server? Both answers end with simply saving
the file to a known location on the server.
