Question

When I do this queryset:

Club.objects.values('district').distinct()

I expect to get this SQL:

SELECT DISTINCT `club_club`.`district` FROM `club_club` ORDER BY `club_club`.`name` ASC

But Django generates this query (adds ‘name’ column):

>>> print Club.objects.values('district').distinct().query
SELECT DISTINCT `club_club`.`district`, `club_club`.`name` FROM `club_club` ORDER BY `club_club`.`name` ASC

What is wrong?

Answer 1

Query you are expecting is invalid order by column has to be in select list if you are using distinct keyword, or else you will get this standard SQL error

Msg 145, Level 15, State 1, Line 1
ORDER BY items must appear in the select list if SELECT DISTINCT is specified.
