- The internal notion of an "OID" or "ROWID" column has been
removed. It's basically not used by any dialect, and the
possibility of its usage with psycopg2's cursor.lastrowid
is basically gone now that INSERT..RETURNING is available.
- Removed "default_order_by()" method on all FromClause
objects.
- profile/compile/select test is 8 function calls over on buildbot 2.4 for some reason, will adjust after checking
the results of this commit
to use regular expressions and format strings, rather
than strptime/strftime, to generically support
pre-1900 dates, dates with microseconds. [ticket:968]
and instead uses subqueries in conjunction with a special
Oracle optimization comment. Allows LIMIT/OFFSET to work
in conjunction with DISTINCT. [ticket:536]
to 'scale'. 'length' is deprecated and is still accepted
with a warning. [ticket:827]
- The 'length' argument to MSInteger, MSBigInteger, MSTinyInteger,
MSSmallInteger and MSYear has been renamed to 'display_width'.
[ticket:827]
- mysql._Numeric now consumes 'unsigned' and 'zerofill' from
the given kw, so that the same kw can be passed along to Numeric
and allow the 'length' deprecation logic to still take effect
- added testlib.engines.all_dialects() to return a dialect for
every db module
- informix added to sqlalchemy.databases.__all__. Since other
"experimental" dbs like access and sybase are there, informix
should be as well.
datetime objects now, not strings. If you'd like to format
dates as strings yourself with SQLite, use a String type.
If you'd like them to return datetime objects anyway despite
their accepting strings as input, make a TypeDecorator around
String - SQLA doesn't encourage this pattern.
match the output of str(somedatetime), i.e. in that the
microseconds are represented as fractional seconds in
string format. [ticket:1090]
- implemented a __legacy_microseconds__ flag on DateTimeMixin which can
be used per-class or per-type instances to get the old behavior, for
compatibility with existing SQLite databases encoded by a previous
version of SQLAlchemy.
- will implement the reverse legacy behavior in 0.4.
- @unsupported now only accepts a single target and demands a reason
for not running the test.
- @exclude also demands an exclusion reason
- Greatly expanded @testing.requires.<feature>, eliminating many
decorators in the suite and signficantly easing integration of
multi-driver support.
- New ORM test base class, and a featureful base for mapped tests
- Usage of 'global' for shared setup going away, * imports as well
- this branch changes query.values() to immediately return an iterator, adds a new "aliased" construct which will be the primary method to get at aliased columns when using values()
- tentative ORM versions of _join and _outerjoin are not yet public, would like to integrate with Query better (work continues in the branch)
- lots of fixes to expressions regarding cloning and correlation. Some apparent ORM bug-workarounds removed.
- to fix a recursion issue with anonymous identifiers, bind parameters generated against columns now just use the name of the column instead of the tablename_columnname label (plus the unique integer counter). this way expensive recursive schemes aren't needed for the anon identifier logic. This, as usual, impacted a ton of compiler unit tests which needed a search-n-replace for the new bind names.
unit tests as part of the default test suite. Added
better uniqueness to the cursor ID [ticket:1001]
- update().values() and insert().values() take keyword
arguments.
- MySQL character set caching is more aggressive but will invalidate the cache if a SET is issued.
- MySQL connection memos are namespaced: info[('mysql', 'server_variable')]
ahead of the tablename in all column expressions as well
as when generating column labels. This prevents cross-
schema name collisions in all cases [ticket:999]
- the "use_schema" argument to compiler.visit_column() is removed. It uses
schema in all cases now.
- added a new test to the PG dialect to test roundtrip insert/update/delete/select
statements with full schema qualification
