That's what I want:
select * from data_player LEFT JOIN data_license ON data_player.id=data_license.id

That's how I try it:
>>> a = Player.objects.select_related()
>>> b = a.License
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'QuerySet' object has no attribute 'License'
