How to determine if a database is SBO2005 or SBO2007?

Hi All

Is the any way in the SDK or SQL in a database to determine if a database is SBO2005A, SBO2005B, SBO2007A or SBO2007B...

We have an add-on that run on both SBO2005 and SBO2007, but it have some functionality that changed in the new SAP version adn therefore we need to do one thing in our code if SBO2005 and another thing if it is run on SBO2007
