31549	Wrong results when executing QuerySet.query.	Lawes	nobody	"We have a class:
{{{
from django.db.models import models
class MyModel(models.Model):
    import_at = models.DateField( db_index=True, null=True, default=None,)
}}}
then I can get some results by:
{{{
queryset = MyModel.objects.filter(import_at__month=5, import_at__year=import_at[0])
print(queryset.count())
}}}
It will print  4

but when I used connection, I got diffrent result:
{{{
from django.db import transaction, connection
with connection.cursor() as cursor:
    cursor.execute(queryset.query)
    print(len(cursor.fetchall()))
}}}
It will print 0

I got 0 !

If I using __month or __year, and get result by cursor.execute(queryset.query), we have diffrent result from connection.
