Description
This is a minor corner case, but as it results in invalid SQL, I figured it should be fixed.
sqlite3:
>>> Proposal.objects.exclude(Q()) Traceback (most recent call last): File "<console>", line 1, in <module> File ".\django\db\models\query.py", line 107, in __repr__ return repr(self._get_data()) File ".\django\db\models\query.py", line 480, in _get_data self._result_cache = list(self.iterator()) File ".\django\db\models\query.py", line 188, in iterator cursor.execute("SELECT " + (self._distinct and "DISTINCT " or "") + ",".join(select) + sql, params) File ".\django\db\backends\util.py", line 19, in execute return self.cursor.execute(sql, params) File ".\django\db\backends\sqlite3\base.py", line 94, in execute return Database.Cursor.execute(self, query, params) OperationalError: near ")": syntax error >>>
postgresql:

(In [7477]) Merged the queryset-refactor branch into trunk.
This is a big internal change, but mostly backwards compatible with existing
code. Also adds a couple of new features.
