Hi,
Have you seen our DBXL Data Query software?
http://www.qdabra.com/en/products/WSSP.aspx
DBXL Data Query is a generic web service that you can install that will allow you to easily connect to SQL tables and pull back just the information you need. It works with browser forms and works without code.
We also have a version of this tool that allows for submitting your InfoPath data to SQL as well.
I would be happy to give you a demo of the tool if you are intersted, you can send me a message through the forum.
