Index lookups
-------------
``raw()`` supports indexing, so if you need only the first result you can
write::
>>> first_person = Person.objects.raw('SELECT * from myapp_person')[0]
However, the indexing and slicing are not performed at the database level. If
you have a big amount of ``Person`` objects in your database, it would be more
efficient to limit the query at the SQL level::
>>> first_person = Person.objects.raw('SELECT * from myapp_person LIMIT 1')[0]
