Thanks for this ticket, however RawQuerySet doesn't implement all methods you can use with QuerySet and is not intended to do this. We cannot mirror QuerySet.count() because there is no annotation/aggregation mechanism in RawQuerySet and wrapping a raw SQL (suggested in stack overflow) can be clunky. You can start a discussion on DevelopersMailingList if you don't agree.

Replying to Mahanth kumar:

No, these are different classes.
