Chunking database records across mock responses

Greetings,

I'm new to SoapUI and was trying to figure out the proper way to accomplish a task I'm working on.  I've got a database of several thousand records and I need to send them via soap back to the caller in chunks of 100 per transmission.  I can write the SQL to do this, but I'm not sure what the right way to go about connecting that up to SoapUI.  I've been able to get soapUI to produce a single response with all the data using a groovy script and a mocked service response.  From reading through the website, I think what I ought to be doing is setting up a test suite with a datasource, datasource loop, property transfer, and mock response; but I'm not sure.

Thanks in advance,
Jonathan
