InfoPath Dev

I have a InfoPath form that I need to create a connection to a SQL database and return some values. I can create with using the Data Connection wizard, but that returns too many records. What I want to do is to pass a parameter. Here is my current code.

function RetreiveMatters::OnClick(eventObj)
{
var objADOAdapter;
objADOAdapter = XDocument.DataObjects("matters").QueryAdapter ;
XDocument.objADOAdapter.Command = "exec _get_Lookup_values @table = 'matter', @filter = 'c.client_code = ''012307'";

//Query the Data Source.
XDocument.Query();
}

What Am I doing Wrong?
TIA

XDocument.Query() is used when your main DOM is connected to a datasource like SQL or Access.

You have a data connection called "matters". You need to query that data connection.
