Todo:
Fixing this to use the DB.

This method is currently not working. The problem is that we ahve an issue in CrudCreate and Virtuoso's LONG VARCHAR column. It appears that there is a bug somewhere in the "php -> odbc -> virtuoso" path. If we are not requesting to return the LONG VARCHAR column, everything works fine.
