Description (last modified by pikicode)

database: mysql 5.7
django version: 3.2
python version: 3.8.1

Model.objects.values('some_datetime_field__date',) returns None in MYSQL

class Inbound(models.Model):
    effective_date = models.DateTimeField(null=False, blank=True)
    number = models.IntegerField()
    # other fields.

daily_changes = Inbound.objects.all().values('effective_date__date')\
  .annotate(total_change=Sum('number')).
Inbound.objects.values('effective_date__date')

The code just returns Nones in Mysql. But it returns date object with Sqlite
