How can I merge data to an Web Form

 I know this may sound like a silly question, but here goes anyway. In my app I have a tool that lets me query my data and return an sql statement in a session variable. I need to know how I could use a web form and the statement to do a merge of the records resulting from the statement. So it would be like an invoice form that produces an invoice (web form) for each order. Can anyone offer any help with this?
