#evaluate ( $dbTool.getVTL("siteNavigation") )
You could make a little tool that retrieves your VTL from the database
and you can use that directly as a parameter to the evaluate directive.
I can't remember if #evaluate is even a directive so you might have to
make a tool to do the evaluations for you, but in either case I don't
think you will have much problem getting this working.
Have you look at the DataSourceResourceLoader in velocity yet? You could
also use this to get VTL from a DataSource.

There are also some docs on the DataSourceResourceLoader in the vel
docs:
