[ticket:2423] + - [bug] Applying a column expression to a select + statement using a label with or without other + modifying constructs will no longer "target" that + expression to the underlying Column; this affects + ORM operations that rely upon Column targeting + in order to retrieve results. That is, a query + like query(User.id, User.id.label('foo')) will now + track the value of each "User.id" expression separately + instead of munging them together. It is not expected + that any users will be impacted by this; however, + a usage that uses select() in conjunction with + query.from_statement() and attempts to load fully + composed ORM entities may not function as expected + if the select() named Column objects with arbitrary + .label() names, as these will no longer target to + the Column objects mapped by that entity. + [ticket:2591] + - [feature] The "unconsumed column names" warning emitted when keys are present in insert.values() or update.values() that aren't in the target table is now an exception. |
