Add clause adaptation for AliasedClass to with_parent()

2017-05-23T15:13:18+00:00

Fixed bug where :meth:`.Query.with_parent` would not work if the
:class:`.Query` were against an :func:`.aliased` construct rather than
a regular mapped class.  Also adds a new parameter
:paramref:`.util.with_parent.from_entity` to the standalone
:func:`.util.with_parent` function as well as
:meth:`.Query.with_parent`.

Treat collation names as identifiers

2017-03-23T19:31:05+00:00

The expression used for COLLATE as rendered by the column-level
:func:`.expression.collate` and :meth:`.ColumnOperators.collate` is now
quoted as an identifier when the name is case sensitive, e.g. has
uppercase characters.  Note that this does not impact type-level
collation, which is already quoted.

Ensure .mapper is set on _ColumnEntity

2016-10-21T14:42:14+00:00

_ColumnEntity didn't seem to have .mapper present, which
due to the way _mapper_zero() worked didn't tend to come
across it.   With :ticket:`3608` _mapper_zero() has
been simplified so make sure this is now present.
Also ensure that _select_from_entity is an entity and
not a mapped class, though this does not seem to matter
at the moment.

Clarify order_by(False)

2016-07-29T22:57:04+00:00

It wasn't clear how this differs from order_by(None);
add more tests and document that this has to do with whether or
not mapper.order_by will be re-enabled as well.

Allow None to cancel Query.group_by()

2016-07-29T22:44:34+00:00

This replicates the same behavior as order_by().

order_by() will also be updated to deprecate passing
of False as this is no longer functionally different
than passing None.

Repair _orm_columns() to accommodate text()

2016-05-05T21:07:40+00:00

Fixed bug whereby passing a :func:`.text` construct to the
:meth:`.Query.group_by` method would raise an error, instead
of intepreting the object as a SQL fragment.

Rename Query._mapper_zero() to Query._entity_zero()

2016-04-19T19:53:50+00:00

To be more descriptive of the use of _mapper_zero(), rename
it to _entity_zero(), but also supply a new _mapper_zero() function
that more strictly returns a mapper.  The existing
_entity_zero() function is renamed to _query_entity_zero.
_only_mapper_zero() is removed as it isn't used.  Divide up the
existing calling functions to refer to the appropriate new method.

- Anonymous labeling is applied to a :attr:`.func` construct that is

2016-02-26T05:20:39+00:00

passed to :func:`.column_property`, so that if the same attribute
is referred to as a column expression twice the names are de-duped,
thus avoiding "ambiguous column" errors.   Previously, the
``.label(None)`` would need to be applied in order for the name
to be de-anonymized.
