| | | | | | | | | | | | | | | | | | Removed ungrammatical apostrophes from documentation, replacing "it's" with "its" where appropriate (but in a few cases with "it is" when that read better). While doing that, I also fixed a couple of minor typos etc. as I noticed them.

* - Added new datatype :class:`.oracle.DATE`, which is a subclass ofMike Bayer2014-03-223-4/+38
| | | | | | | | | | | | :class:`.DateTime`. As Oracle has no "datetime" type per se, it instead has only ``DATE``, it is appropriate here that the ``DATE`` type as present in the Oracle dialect be an instance of :class:`.DateTime`. This issue doesn't change anything as far as the behavior of the type, as data conversion is handled by the DBAPI in any case, however the improved subclass layout will help the use cases of inspecting types for cross-database compatibility. Also removed uppercase ``DATETIME`` from the Oracle dialect as this type isn't functional in that context. fixes #2987

* | - The precision used when coercing a returned floating point value toMike Bayer2013-11-221-4/+1
| | | | | | | | | | | | | | | | | | | | 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]

* - cx_oracle seems to have a bug here though it is hard to track downMike Bayer2013-08-272-2/+0
| | | | - cx_oracle dialect doesn't use normal col names, lets just not rely on that for now
* - A rework to the way that "quoted" identifiers are handled, in thatMike Bayer2013-08-271-1/+2
| | | | | | | | | | | | | | | | 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]
* - rework of correlation, continuing on #2668, #2746Mike Bayer2013-06-261-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | - add support for correlations to propagate all the way in; because correlations require context now, need to make sure a select enclosure of any level takes effect any number of levels deep. - fix what we said correlate_except() was supposed to do when we first released #2668 - "the FROM clause is left intact if the correlated SELECT is not used in the context of an enclosing SELECT..." - it was not considering the "existing_froms" collection at all, and prohibited additional FROMs from being placed in an any() or has(). - add test for multilevel any() - lots of docs, including glossary entries as we really need to define "WHERE clause", "columns clause" etc. so that we can explain correlation better - based on the insight that a SELECT can correlate anything that ultimately came from an enclosing SELECT that links to this one via WHERE/columns/HAVING/ORDER BY, have the compiler keep track of the FROM lists that correspond in this way, link it to the asfrom flag, so that we send to _get_display_froms() the exact list of candidate FROMs to correlate. no longer need any asfrom logic in the Select() itself - preserve 0.8.1's behavior for correlation when no correlate options are given, not to mention 0.7 and prior's behavior of not propagating implicit correlation more than one level.. this is to reduce surprises/hard-to-debug situations when a user isn't trying to correlate anything.

* Fixed table reflection for Oracle when accessing a synonym that refersMike Bayer2012-12-091-58/+93
| | | | | | | | | | to a DBLINK remote database; while the syntax has been present in the Oracle dialect for some time, up until now it has never been tested. The syntax has been tested against a sample database linking to itself, however there's still some uncertainty as to what should be used for the "owner" when querying the remote database for table information. Currently, the value of "username" from user_db_links is used to match the "owner". [ticket:2619]
