@ -414,6 +414,11 @@ A couple of subtleties that are worth mentioning:
* When using ``values()`` together with ``distinct()``, be aware that
ordering can affect the results. See the note in the `distinct()`_
section, above, for details.
* If you use a ``values()`` clause after an ``extra()`` clause,
any fields defined by a ``select`` argument in the ``extra()``
must be explicitly included in the ``values()`` clause. However,
if the ``extra()`` clause is used after the ``values()``, the
fields added by the select will be included automatically.
