``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]
|
||||
|
||||
However, the indexing and slicing are not performed at the database level. If
|
||||
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]
|
||||
>>> first_person = Person.objects.raw('SELECT * FROM myapp_person LIMIT 1')[0]
