An overhaul of expression handling for special symbols particularly

2013-10-23T21:44:52+00:00

with conjunctions, e.g.
``None`` :func:`.expression.null` :func:`.expression.true`
:func:`.expression.false`, including consistency in rendering NULL
in conjunctions, "short-circuiting" of :func:`.and_` and :func:`.or_`
expressions which contain boolean constants, and rendering of
boolean constants and expressions as compared to "1" or "0" for backends
that don't feature ``true``/``false`` constants. [ticket:2804]

- Removed some now unneeded version checks [ticket:2829] courtesy alex gaynor

2013-09-23T00:35:40+00:00

- The :meth:`.Operators.notin_` operator added in 0.8 now properly

2013-08-07T18:28:45+00:00

produces the negation of the expression "IN" returns
when used against an empty collection.  Also in 0.8.3.

- remove the ``iter()`` with notimplemented since it interferes

2013-06-03T20:32:12+00:00

with legitimate iterable detection, [ticket:2726]

Fully implemented the IS and IS NOT operators with

2013-04-22T23:12:47+00:00

regards to the True/False constants.  An expression like
``col.is_(True)`` will now render ``col IS true``
on the target platform, rather than converting the True/
False constant to an integer bound parameter.
This allows the ``is_()`` operator to work on MySQL when
given True/False constants.
[ticket:2682]

The :meth:`.ColumnOperators.in_` operator will now coerce

2013-02-02T21:17:58+00:00

values of ``None`` to :func:`.null`.
[ticket:2496]

- BinaryExpression now keeps track of "left" and "right" as passed in,

2012-12-02T17:37:52+00:00

so that they can be compared in ``__nonzero__`` prior to their
self_group() step.  [ticket:2621]

Fixed a gotcha where inadvertently calling list() on a

2012-11-18T15:38:02+00:00

      :class:`.ColumnElement` would go into an endless loop, if
      :meth:`.ColumnOperators.__getitem__` were implemented.
      A new NotImplementedError is emitted via ``__iter__()``.

Added :meth:`.ColumnOperators.notin_`,

2012-10-24T20:01:17+00:00

:meth:`.ColumnOperators.notlike`,
:meth:`.ColumnOperators.notilike` to :class:`.ColumnOperators`.
[ticket:2580]

- move most/all operator specific tests into test_operator, convert fully to TOT
