| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python ``Decimal`` via string is now configurable. The flag ``decimal_return_scale`` is now supported by all :class:`.Numeric` and :class:`.Float` types, which will ensure this many digits are taken from the native floating point value when it is converted to string. If not present, the type will make use of the value of ``.scale``, if the type supports this setting and it is non-None. Otherwise the original default length of 10 is used. [ticket:2867]

| | | | | | | | | | | | | | | | | | | | 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]

| | | | | | | | | | | | | | | | | | specified) is now copied when used in a typed expression, and the new copy is assigned the actual type of the compared column. Previously, this logic would occur on the given :func:`.bindparam` in place. Additionally, a similar process now occurs for :func:`.bindparam` constructs passed to :meth:`.ValuesBase.values` for a :class:`.Insert` or :class:`.Update` construct. [ticket:2850]
* | - Fixed bug where :func:`.type_coerce` would not interpret ORMMike Bayer2013-10-211-2/+2

* | - The typing system now handles the task of rendering "literal bind" values,Mike Bayer2013-10-203-46/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | e.g. values that are normally bound parameters but due to context must be rendered as strings, typically within DDL constructs such as CHECK constraints and indexes (note that "literal bind" values become used by DDL as of :ticket:`2742`). A new method :meth:`.TypeEngine.literal_processor` serves as the base, and :meth:`.TypeDecorator.process_literal_param` is added to allow wrapping of a native literal rendering method. [ticket:2838] - enhance _get_colparams so that we can send flags like literal_binds into INSERT statements - add support in PG for inspecting standard_conforming_strings - add a new series of roundtrip tests based on INSERT of literal plus SELECT for basic literal rendering in dialect suite
* | - add a type_coerce() step within Enum, Boolean to the CHECK constraint,Mike Bayer2013-10-202-3/+6
| | | | | | | | | | | | | | | | so that the custom type isn't exposed to an operation that is against the "impl" type's constraint, [ticket:2842] - this change showed up as some recursion overflow in pickling with labels, add a __reduce__() there....pickling of expressions is less and less something that's very viable...
* | - The :meth:`.Table.tometadata` method now produces copies ofMike Bayer2013-10-181-13/+15
| | | | | | | | | | | | | | | | | | | | all :attr:`.SchemaItem.info` dictionaries from all :class:`.SchemaItem` objects within the structure including columns, constraints, foreign keys, etc. As these dictionaries are copies, they are independent of the original dictionary. Previously, only the ``.info`` dictionary of :class:`.Column` was transferred within this operation, and it was only linked in place, not copied. [ticket:2716]
* | The ``.unique`` flag on :class:`.Index` could be produced as ``None``Mike Bayer2013-10-141-1/+6
| | | | | | | | | | | | if it was generated from a :class:`.Column` that didn't specify ``unique`` (where it defaults to ``None``). The flag will now always be ``True`` or ``False``. [ticket:2825]

| | | | | | | :func:`.foreign` on a :class:`.Column` before association with a parent :class:`.Table` could produce issues related to the parent table not rendering within joins, due to the inherent copy operation performed by an annotation. [ticket:2813]

* - A rework to the way that "quoted" identifiers are handled, in thatMike Bayer2013-08-277-115/+245
| | | | | | | | | | | | | | | | instead of relying upon various ``quote=True`` flags being passed around, these flags are converted into rich string objects with quoting information included at the point at which they are passed to common schema constructs like :class:`.Table`, :class:`.Column`, etc. This solves the issue of various methods that don't correctly honor the "quote" flag such as :meth:`.Engine.has_table` and related methods. The :class:`.quoted_name` object is a string subclass that can also be used explicitly if needed; the object will hold onto the quoting preferences passed and will also bypass the "name normalization" performed by dialects that standardize on uppercase symbols, such as Oracle, Firebird and DB2. The upshot is that the "uppercase" backends can now work with force-quoted names, such as lowercase-quoted names and new reserved words. [ticket:2812]

* - The ``version_id_generator`` parameter of ``Mapper`` can now be specifiedMike Bayer2013-08-253-151/+113
| | | | | | | | | | | | | | | | | | | | | to rely upon server generated version identifiers, using triggers or other database-provided versioning features, by passing the value ``False``. The ORM will use RETURNING when available to immediately load the new version identifier, else it will emit a second SELECT. [ticket:2793] - The ``eager_defaults`` flag of :class:`.Mapper` will now allow the newly generated default values to be fetched using an inline RETURNING clause, rather than a second SELECT statement, for backends that support RETURNING. - Added a new variant to :meth:`.ValuesBase.returning` called :meth:`.ValuesBase.return_defaults`; this allows arbitrary columns to be added to the RETURNING clause of the statement without interfering with the compilers usual "implicit returning" feature, which is used to efficiently fetch newly generated primary key values. For supporting backends, a dictionary of all fetched values is present at :attr:`.ResultProxy.returned_defaults`. - add a glossary entry for RETURNING - add documentation for version id generation, [ticket:867]
