ORDER BY or GROUP BY on a simple label name at all; when in fact,
we had forgotten that 0.9 was already emitting ORDER BY on a simple
label name for all backends, as described in :ref:`migration_1068`,
- as 1.0 had rewritten this logic as part of :ticket:`2992`.
-
- In 1.0.2, the bug is fixed both that SQL Server, Firebird and others
- will again emit ORDER BY on a simple label name when passed a
- :class:`.Label` construct that is expressed in the columns clause,
- and no backend will emit GROUP BY on a simple label name in this case,
- as even Postgresql can't reliably do GROUP BY on a simple name
- in every case.
+ even though 1.0 includes a rewrite of this logic as part of
+ :ticket:`2992`. As far
+ as emitting GROUP BY against a simple label, even Postgresql has
+ cases where it will raise an error even though the label to group
+ on should be apparent, so it is clear that GROUP BY should never
+ be rendered in this way automatically.
+
+ In 1.0.2, SQL Server, Firebird and others will again emit ORDER BY on
+ a simple label name when passed a
+ :class:`.Label` construct that is also present in the columns clause.
+ Additionally, no backend will emit GROUP BY against the simple label
+ name only when passed a :class:`.Label` construct.
