Hello,
DB for LabVIEW is a new Toolkit Compatible with LabVIEW can help you a lot to do what you want.
It uses the LV Database and Connectivity Toolkit to connect your existing database, automatically get the database structure and columns data types. Then, with this information, it automatically generates a LabVIEW Polymorphic VI for your database, and this VI will returns your database records in clusters instead of variants.

You can try this toolkit by downloading it on http://studiobods.com/en/produits.html
