Description
\site-packages\django\db\backends\mysql\operations.py line 58
def date_trunc_sql(self, lookup_type, field_name, tzname=None):
field_name = self._convert_field_to_tz(field_name, tzname)
fields = {
'year': '%%Y-01-01',
'month': '%%Y-%%m-01',
} # Use double percents to escape.
the problem is here.
'year': '%%Y-01-01',
'month': '%%Y-%%m-01',
this will generate the sql.
SELECT DISTINCT CAST(DATE_FORMAT([table name], '%%Y-01-01') AS DATE) AS `datefield
the format %%Y-01-01 is not right for mysql.
