accepts the Inspector object as the first
argument, preceding "table". Code which
uses the 0.7 version of this very new
event will need modification to add the
"inspector" object as the first argument.

when set to False on Table, the Table can be autoloaded
without existing columns being replaced. Allows
more flexible chains of Table construction/reflection
to be constructed, including that it helps with
combining Declarative with table reflection.
See the new example on the wiki. [ticket:2356]
- [bug] Improved the API for add_column() such that
if the same column is added to its own table,
an error is not raised and the constraints
don't get doubled up. Also helps with some
reflection/declarative patterns. [ticket:2356]
list of index names and the names of columns
within those indexes. [ticket:2269]
- rewrite unicode reflection test to be of more general use on
broken backends
now allows for the reflection process to take
effect for a Table object that's already been
defined; when autoload=True and extend_existing=True
are both set, the full set of columns will be
reflected from the Table which will then
*overwrite* those columns already present,
rather than no activity occurring. Columns that
are present directly in the autoload run
will be used as always, however.

option to Inspector.get_table_names
wasn't implementing the sort properly, replaced
with the existing sort algorithm
- clean up metadata usage in reflection tests
- MetaData() accepts "schema" and "quote_schema"
arguments, which will be applied to the same-named
arguments of a Table
or Sequence which leaves these at their default
of ``None``.
- Sequence accepts "quote_schema" argument
- tometadata() for Table will use the "schema"
of the incoming MetaData for the new Table
if the schema argument is explicitly "None"
- Added CreateSchema and DropSchema DDL
constructs - these accept just the string
name of a schema and a "quote" flag.
- When using default "schema" with MetaData,
ForeignKey will also assume the "default" schema
when locating remote table. This allows the "schema"
argument on MetaData to be applied to any
set of Table objects that otherwise don't have
a "schema".
- a "has_schema" method has been implemented
on dialect, but only works on Postgresql so far.

a foreign-key referenced table with schema in
the current search path; an explicit schema will
be applied to the referenced table only if
it actually matches that of the referencing table,
which also has an explicit schema. Previously
it was assumed that "current" schema was synonymous
with the full search_path. [ticket:2249]
on windows, after aggressive exclusion of a wide variety
of tests. Not clear to what degree the failures are related to
version 5.5 vs. the usage of windows, in particular the ON UPDATE CASCADE
immediately crashes the server. The features being tested here are all
edge cases not likely to be used in typical MySQL environments.
- Removed the "adjust casing" step that would
fail when reflecting a table on MySQL
on windows with a mixed case name. After some
experimenting with a windows MySQL server, it's
been determined that this step wasn't really
helping the situation much; MySQL does not return
FK names with proper casing on non-windows
platforms either, and removing the step at
least allows the reflection to act more like
it does on other OSes. A warning here
has been considered but its difficult to
determine under what conditions such a warning
can be raised, so punted on that for now -
added some docs instead. [ticket:2181]
- supports_sane_rowcount will be set to False
if using MySQLdb and the DBAPI doesn't provide
the constants.CLIENT module.
by a new pair of flags 'keep_existing' and
'extend_existing'. 'extend_existing' is equivalent
to 'useexisting' - the existing Table is returned,
and additional constructor elements are added.
With 'keep_existing', the existing Table is returned,
but additional constructor elements are not added -
these elements are only applied when the Table
is newly created. [ticket:2109]
outside of "sqlalchemy" and under "test/".
Rationale:
- coverage plugin works without issue, without need for an awkward
additional package install
- command line for "nosetests" isn't polluted with SQLAlchemy options

columns in a reflected table would cause an attempt
to remove the reflected constraint from the table
a second time, raising a KeyError. [ticket:1865]
- fixed test of error message now that we've improved it
(didn't know that msg had an assertion)
to get_primary_keys() except returns a dict that includes the
name of the constraint, for supported backends (PG so far).
[ticket:1769]
- Postgresql reflects the name of primary key constraints,
if one exists. [ticket:1769]
produces BLOB, BYTEA, or a similar "long binary" type.
New base BINARY and VARBINARY
types have been added to access these MySQL/MS-SQL specific
types in an agnostic way [ticket:1664].
test user has DBA privs, and all objects can be created /dropped.
- added ORDER BY to oracle column listing
- Oracle all_tables always limits to current user if schema not given.
- views reflect - added documentation + a unit test for this.
- Table(autoload) with no bind produces an error message specific to
the fact that autoload_with should be the first option to try.
