~~~~~~~~~~~~~~~~~~
.. versionadded:: 1.2
This method is for controlling which database the ``QuerySet`` will be
evaluated against if you are using more than one database. The only argument
this method takes is the alias of a database, as defined in
:settings:`DATABASES`.
For example::
# queries the database with the 'default' alias.
>>> Entry.objects.all()
# queries the database with the 'backup' alias
>>> Entry.objects.using('backup')
