You could design a controller action which will fetch the pdf path from the database and stream it to the response:

public ActionResult ShowPdf()
{
    string path = ... fetch path from database
    if (!System.IO.File.Exists(path))
    {
        // the file was not found
        throw new HttpException(404, "Not found");
    }
    return File(path, "application/pdf", "test.pdf");
}

and then you could create a link to this action in your view:

<%= Html.ActionLink("download pdf", "showpdf", "somecontroller") %>
