InfoPath Dev

hi,

Im NewBie to Infopath.Im able to cretae new Infopath Form that can submit Data to SQL Server DataBase with out using the webservice(we are creating the datasource from the database).

But I want to know is there ant way to submit form data to database of already existing form without using webservice(since this form already have primary datasource ).In detail we have already developed some forms that submit to share point now can i submit that form data to database.if possible means please specify the process.

The only way I know of to do this without using web services is to write custom code. This link has some basic code for creating a SQL connection in code.
