i'm new at using DataRows. i used SQLTemplate to returned the list of
dataobjects....instead of a list of DataRows. i'm trying to figure out how to go about
this returning a list of DataRows from a SQLTemplate....does anyone know of a cayenne
class that can do this? so i don't have to resort to writing another set of code to fix
this problem..i'm trying to use as much of cayenne api's as possible.
