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]
slicing into None, so that needless OFFSET
clauses are not invoked.
- mssql: "0" is accepted as an argument for limit() which
will produce "TOP 0". [ticket:2222]
- add tests to default compiler test for LIMIT/OFFSET generation
off of reflected default value, allowing
a round trip CREATE TABLE to work.
This is consistent with other dialects
that also maintain the exact form of
the default. [ticket:2189]
MATCH operator. A potential floating-point
inaccuracy issue was fixed, and certain tests
of the MATCH operator only execute within an
EN-oriented locale for now. [ticket:2175].

as the value passed to select.limit()/offset()
will be coerced to integer. [ticket:2116]
(also in 0.6.7)
- Oracle dialect adds use_binds_for_limits=False
create_engine() flag, will render the LIMIT/OFFSET
values inline instead of as binds, reported to
modify the execution plan used by Oracle.

that the SQL Server and MySQL versions, which
add extra arguments, are also still available
from those dialects. [ticket:2081]
for the column itself or for a name-generated
bind parameter, such as names with special
characters, underscores, non-ascii characters,
now properly translate bind parameter keys when
talking to cx_oracle. [ticket:2100] (Also

access to the cls/self.tables/classes registries
- express orm/_base.py ORMTest in terms of engine/_base.py TablesTest,
factor out common steps into TablesTest, remove AltEngineTest as a
separate class. will further consolidate these base classes
typically when using the Inspector interface, to
use sys.sql_modules instead of the information schema,
thereby allowing views definitions longer than 4000
characters to be fully returned. [ticket:2071]
object via its 'metadata' argument, will be
included in CREATE/DROP statements within
metadata.create_all() and metadata.drop_all(),
including "checkfirst" logic. [ticket:2055]
normalized via os.path.abspath(), so that directory changes
within the process don't affect the ultimate location
of a relative file path. [ticket:2036]
as *args, interpreted by the Postgresql dialect
as DISTINCT ON (<expr>). [ticket:1069]
- select.distinct() now accepts column expressions
as *args, interpreted by the Postgresql dialect
as DISTINCT ON (<expr>). Note this was already
available via passing a list to the `distinct`
keyword argument to select(). [ticket:1069]
- select.prefix_with() accepts multiple expressions
(i.e. *expr), 'prefix' keyword argument to select()
accepts a list or tuple.
- Passing a string to the `distinct` keyword argument
of `select()` for the purpose of emitting special
MySQL keywords (DISTINCTROW etc.) is deprecated -
use `prefix_with()` for this.
- put kw arguments to select() in order
- restore docs for _SelectBase, renamed from _SelectBaseMixin
call are now wrapped in sqlalchemy.exc.StatementError,
and the text of the SQL statement and repr() of params
is included. This makes it easier to identify statement
executions which fail before the DBAPI becomes
involved. [ticket:2015]
of the auto-generated sequence of a SERIAL column,
which currently only occurs if implicit_returning=False,
now accommodates if the table + column name is greater
than 63 characters using the same logic Postgresql uses.

FB/Interbase version idents are parsed into a structure
such as (8, 1, 1, 'interbase') or (2, 1, 588, 'firebird')
so they can be distinguished. [ticket:1885]
- fixed relfection of the "autoincrement" flag against a default
placed on the column.
per-connection methods for sqlite, postgresql, psycopg2 dialects
- move isolation test suite to test engines/test_transaction

result, also generates procs that are not used in most cases. simplify the approach
by passing type to _exec_default() to be used if needed by _execute_scalar(),
looking for the proc on just t._autoincrement_column in post_insert().
