InfoPath Dev

I'm brand new to InfoPath and VB. Can someone help me with the correct syntaxt to create my own query without breaking the data field bindings? I have one query field that I'll use to select a record(s) from a SQL databse. I want to modify the query so that I can format a date field to return formatted, retrieve all the rest of the fields and populate the InfoPath form accordingly. I know the SQL query statement to use in MSSQL but I don't know how to apply it to a button.

 Thanks in advance

In the wizard for the SQL receive data connection, there should be an option for specifying the SQL Select Text. Double click the button and add a rule to query that data connection.
