- cleaned up tutorial w.r.t. eagerload, added a section for contains_eager as this function
is equally important
- added better linkages in sqlalchemy.orm reference documentation, updated antiquated
docs for contains_eager(), got aliased()/AliasedClass documented as well as Sphinx will
allow us
- declarative now accepts mixin classes directly, as a means
to provide common functional and column-based elements on
all subclasses, as well as a means to propagate a fixed
set of __table_args__ or __mapper_args__ to subclasses.
For custom combinations of __table_args__/__mapper_args__ from
an inherited mixin to local, descriptors can now be used.
New details are all up in the Declarative documentation.
Thanks to Chris Withers for putting up with my strife
on this. [ticket:1707]
ensure that it fully counts all object identities present
in the result, even in the case where joins may conceal
multiple identities for two or more rows. As a bonus,
one() can now also be called with a query that issued
from_statement() to start with since it no longer modifies
the query. [ticket:1688]
API, used for any expression construct that can be sent to
execute(). FunctionElement now inherits Executable so that
it gains execution_options(), which are also propagated
to the select() that's generated within execute().
Executable in turn subclasses _Generative which marks
any ClauseElement that supports the @_generative
decorator - these may also become "public" for the benefit
of the compiler extension at some point.
values from a scalar or collection attribute into the new session
during an add() operation. This so that the flush() operation
will also delete or modify rows of those disconnected items.
to be compared to another set, typically with IN against
composite primary keys or similar. Also accepts an
IN with multiple columns. The "scalar select can
have only one column" error message is removed - will
rely upon the database to report problems with
col mismatch.
of statements have more consistent behavior w.r.t.
parenthesizing. Each compound element embedded within
another will now be grouped with parenthesis - previously,
the first compound element in the list would not be grouped,
as SQLite doesn't like a statement to start with
parenthesis. However, Postgresql in particular has
precedence rules regarding INTERSECT, and it is
more consistent for parenthesis to be applied equally
to all sub-elements. So now, the workaround for SQLite
is also what the workaround for PG was previously -
when nesting compound elements, the first one usually needs
".alias().select()" called on it to wrap it inside
of a subquery. [ticket:1665]
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].
- added READMEs to all examples in each __init__.py and added to sphinx documentation
- added versioning example
- removed vertical/vertical.py, the dictlikes are more straightforward
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.
applies the SQLite keyword "AUTOINCREMENT" to columns within DDL -
will prevent generation of a separate PRIMARY KEY constraint.
[ticket:1016]
- added docs
- fixed underlines in mysql.rst
- updated oursql driver with latest fixes using options. [ticket:1613]
- all the MySQL drivers get a shoutout in the docs
- marked tests that OurSQL has problems with (only three), passes 100% now
- removed "key" accessor of Function, Grouping - this doesn't seem to be used for anything
- various formatting
- documented the four "Element" classes in the compiler extension as per [ticket:1590]
- removed doctest stuff
- redid session docs for sqlsoup
- sqlsoup stays within the transaction of a Session now, is explcitly autocommit=False by default and includes commit()/rollback() methods
- sqlsoup db.<sometable>.update() and delete() now call
query(cls).update() and delete(), respectively.
- sqlsoup now has execute() and connection(), which call upon
the Session methods of those names, ensuring that the bind is
in terms of the SqlSoup object's bind.
construct and extends the generic Enum type. Automatically
associates itself with tables and their parent metadata
to issue the appropriate CREATE TYPE/DROP TYPE
commands as needed, supports unicode labels, supports
reflection. [ticket:1511]
- MySQL ENUM now subclasses the new generic Enum type, and also handles
unicode values implicitly, if the given labelnames are unicode
objects.
- Added a new Enum generic type, currently supported on
Postgresql and MySQL. Enum is a schema-aware object
to support databases which require specific DDL in
order to use enum or equivalent; in the case of PG
it handles the details of `CREATE TYPE`, and on
other databases without native enum support can
support generation of CHECK constraints.
[ticket:1109] [ticket:1511]
- types documentation updates
- some cleanup on schema/expression docs
