``raw()`` supports indexing, so if you need only the first result you can

write::



    >>> first_person = Person.objects.raw('SELECT * from myapp_person')[0]

    >>> first_person = Person.objects.raw('SELECT * FROM myapp_person')[0]

you have a large number of ``Person`` objects in your database, it is more

efficient to limit the query at the SQL level::

    >>> first_person = Person.objects.raw('SELECT * FROM myapp_person LIMIT 1')[0]
