Update Flask-SQLAlchemy from 2.4.4 to 3.1.1.

Changelog

3.1.1

-------------

Released 2023-09-11

-   Deprecate the ``__version__`` attribute. Use feature detection, or
 ``importlib.metadata.version(&quot;flask-sqlalchemy&quot;)``, instead. :issue:`5230`

3.1.0

-------------

Released 2023-09-11

-   Drop support for Python 3.7.  :pr:`1251`
-   Add support for the SQLAlchemy 2.x API via ``model_class`` parameter. :issue:`1140`
-   Bump minimum version of SQLAlchemy to 2.0.16.
-   Remove previously deprecated code.
-   Pass extra keyword arguments from ``get_or_404`` to ``session.get``. :issue:`1149`
-   Fix bug with finding right bind key for clause statements. :issue:`1211`

3.0.5

-------------

Released 2023-06-21

-   ``Pagination.next()`` enforces ``max_per_page``. :issue:`1201`
-   Improve type hint for ``get_or_404`` return value to be non-optional. :pr:`1226`

3.0.4

-------------

Released 2023-06-19

-   Fix type hint for ``get_or_404`` return value. :pr:`1208`
-   Fix type hints for pyright (used by VS Code Pylance extension). :issue:`1205`

3.0.3

-------------

Released 2023-01-31

-   Show helpful errors when mistakenly using multiple ``SQLAlchemy`` instances for the
 same app, or without calling ``init_app``. :pr:`1151`
-   Fix issue with getting the engine associated with a model that uses polymorphic
 table inheritance. :issue:`1155`

3.0.2

-------------

Released 2022-10-14

-   Update compatibility with SQLAlchemy 2. :issue:`1122`

3.0.1

-------------

Released 2022-10-11

-   Export typing information instead of using external typeshed definitions.
 :issue:`1112`
-   If default engine options are set, but ``SQLALCHEMY_DATABASE_URI`` is not set, an
 invalid default bind will not be configured. :issue:`1117`

3.0.0

-------------

Released 2022-10-04

-   Drop support for Python 2, 3.4, 3.5, and 3.6.
-   Bump minimum version of Flask to 2.2.
-   Bump minimum version of SQLAlchemy to 1.4.18.
-   Remove previously deprecated code.
-   The session is scoped to the current app context instead of the thread. This
 requires that an app context is active. This ensures that the session is cleaned up
 after every request.
-   An active Flask application context is always required to access ``session`` and
 ``engine``, regardless of if an application was passed to the constructor.
 :issue:`508, 944`
-   Different bind keys use different SQLAlchemy ``MetaData`` registries, allowing
 tables in different databases to have the same name. Bind keys are stored and looked
 up on the resulting metadata rather than the model or table.
-   ``SQLALCHEMY_DATABASE_URI`` does not default to ``sqlite:///:memory:``. An error is
 raised if neither it nor ``SQLALCHEMY_BINDS`` define any engines. :pr:`731`
-   Configuring SQLite with a relative path is relative to ``app.instance_path`` instead
 of ``app.root_path``. The instance folder is created if necessary. :issue:`462`
-   Added ``get_or_404``, ``first_or_404``, ``one_or_404``, and ``paginate`` methods to
 the extension object. These use SQLAlchemy&#x27;s preferred ``session.execute(select())``
 pattern instead of the legacy query interface. :issue:`1088`
-   Setup methods that create the engines and session are renamed with a leading
 underscore. They are considered internal interfaces which may change at any time.
-   All parameters to ``SQLAlchemy`` except ``app`` are keyword-only.
-   Renamed the ``bind`` parameter to ``bind_key`` and removed the ``app`` parameter
 from various ``SQLAlchemy`` methods.
-   The extension object uses ``__getattr__`` to alias names from the SQLAlchemy
 package, rather than copying them as attributes.
-   The extension object is stored directly as ``app.extensions[&quot;sqlalchemy&quot;]``.
 :issue:`698`
-   The session class can be customized by passing the ``class_`` key in the
 ``session_options`` parameter. :issue:`327`
-   ``SignallingSession`` is renamed to ``Session``.
-   ``Session.get_bind`` more closely matches the base implementation.
-   Model classes and the ``db`` instance are available without imports in
 ``flask shell``. :issue:`1089`
-   The ``CamelCase`` to ``snake_case`` table name converter handles more patterns
 correctly. If model that was already created in the database changed, either use
 Alembic to rename the table, or set ``__tablename__`` to keep the old name.
 :issue:`406`
-   ``Model`` ``repr`` distinguishes between transient and pending instances.
 :issue:`967`
-   A custom model class can implement ``__init_subclass__`` with class parameters.
 :issue:`1002`
-   ``db.Table`` is a subclass instead of a function.
-   The ``engine_options`` parameter is applied as defaults before per-engine
 configuration.
-   ``SQLALCHEMY_BINDS`` values can either be an engine URL, or a dict of engine options
 including URL, for each bind. ``SQLALCHEMY_DATABASE_URI`` and
 ``SQLALCHEMY_ENGINE_OPTIONS`` correspond to the ``None`` key and take precedence.
 :issue:`783`
-   Engines are created when calling ``init_app`` rather than the first time they are
 accessed. :issue:`698`
-   ``db.engines`` exposes the map of bind keys to engines for the current app.
-   ``get_engine``, ``get_tables_for_bind``, and ``get_binds`` are deprecated.
-   SQLite driver-level URIs that look like ``sqlite:///file:name.db?uri=true`` are
 supported. :issue:`998, 1045`
-   SQLite engines do not use ``NullPool`` if ``pool_size`` is 0.
-   MySQL engines use the &quot;utf8mb4&quot; charset by default. :issue:`875`
-   MySQL engines do not set ``pool_size`` to 10.
-   MySQL engines don&#x27;t set a default for ``pool_recycle`` if not using a queue pool.
 :issue:`803`
-   ``Query`` is renamed from ``BaseQuery``.
-   Added ``Query.one_or_404``.
-   The query class is applied to ``backref`` in ``relationship``. :issue:`417`
-   Creating ``Pagination`` objects manually is no longer a public API. They should be
 created with ``db.paginate`` or ``query.paginate``. :issue:`1088`
-   ``Pagination.iter_pages`` and ``Query.paginate`` parameters are keyword-only.
-   ``Pagination`` is iterable, iterating over its items. :issue:`70`
-   Pagination count query is more efficient.
-   ``Pagination.iter_pages`` is more efficient. :issue:`622`
-   ``Pagination.iter_pages`` ``right_current`` parameter is inclusive.
-   Pagination ``per_page`` cannot be 0. :issue:`1091`
-   Pagination ``max_per_page`` defaults to 100. :issue:`1091`
-   Added ``Pagination.first`` and ``last`` properties, which give the number of the
 first and last item on the page. :issue:`567`
-   ``SQLALCHEMY_RECORD_QUERIES`` is disabled by default, and is not enabled
 automatically with ``app.debug`` or ``app.testing``. :issue:`1092`
-   ``get_debug_queries`` is renamed to ``get_recorded_queries`` to better match the
 config and functionality.
-   Recorded query info is a dataclass instead of a tuple. The ``context`` attribute is
 renamed to ``location``. Finding the location uses a more inclusive check.
-   ``SQLALCHEMY_TRACK_MODIFICATIONS`` is disabled by default. :pr:`727`
-   ``SQLALCHEMY_COMMIT_ON_TEARDOWN`` is deprecated. It can cause various design issues
 that are difficult to debug. Call ``db.session.commit()`` directly instead.
 :issue:`216`

2.5.1

-------------

Released 2021-03-18

-   Fix compatibility with Python 2.7.

2.5.0

-------------

Released 2021-03-18

-   Update to support SQLAlchemy 1.4.
-   SQLAlchemy ``URL`` objects are immutable. Some internal methods have changed to
 return a new URL instead of ``None``. :issue:`885`

Changelog

2.0.36

:released: October 15, 2024

 .. change::
     :tags: bug, schema
     :tickets: 11317

     Fixed bug where SQL functions passed to
     :paramref:`_schema.Column.server_default` would not be rendered with the
     particular form of parenthesization now required by newer versions of MySQL
     and MariaDB. Pull request courtesy of huuya.

 .. change::
     :tags: bug, orm
     :tickets: 11912

     Fixed bug in ORM bulk update/delete where using RETURNING with bulk
     update/delete in combination with ``populate_existing`` would fail to
     accommodate the ``populate_existing`` option.

 .. change::
     :tags: bug, orm
     :tickets: 11917

     Continuing from :ticket:`11912`, columns marked with
     :paramref:`.mapped_column.onupdate`,
     :paramref:`.mapped_column.server_onupdate`, or :class:`.Computed` are now
     refreshed in ORM instances when running an ORM enabled UPDATE with WHERE
     criteria, even if the statement does not use RETURNING or
     ``populate_existing``.

 .. change::
     :tags: usecase, orm
     :tickets: 11923

     Added new parameter :paramref:`_orm.mapped_column.hash` to ORM constructs
     such as :meth:`_orm.mapped_column`, :meth:`_orm.relationship`, etc.,
     which is interpreted for ORM Native Dataclasses in the same way as other
     dataclass-specific field parameters.

 .. change::
     :tags: bug, postgresql, reflection
     :tickets: 11961

     Fixed bug in reflection of table comments where unrelated text would be
     returned if an entry in the ``pg_description`` table happened to share the
     same oid (objoid) as the table being reflected.

 .. change::
     :tags: bug, orm
     :tickets: 11965

     Fixed regression caused by fixes to joined eager loading in :ticket:`11449`
     released in 2.0.31, where a particular joinedload case could not be
     asserted correctly.   We now have an example of that case so the assertion
     has been repaired to allow for it.


 .. change::
     :tags: orm, bug
     :tickets: 11973

     Improved the error message emitted when trying to map as dataclass a class
     while also manually providing the ``__table__`` attribute.
     This usage is currently not supported.

 .. change::
     :tags: mysql, performance
     :tickets: 11975

     Improved a query used for the MySQL 8 backend when reflecting foreign keys
     to be better optimized.   Previously, for a database that had millions of
     columns across all tables, the query could be prohibitively slow; the query
     has been reworked to take better advantage of existing indexes.

 .. change::
     :tags: usecase, sql
     :tickets: 11978

     Datatypes that are binary based such as :class:`.VARBINARY` will resolve to
     :class:`.LargeBinary` when the :meth:`.TypeEngine.as_generic()` method is
     called.

 .. change::
     :tags: postgresql, bug
     :tickets: 11994

     The :class:`.postgresql.JSON` and :class:`.postgresql.JSONB` datatypes will
     now render a &quot;bind cast&quot; in all cases for all PostgreSQL backends,
     including psycopg2, whereas previously it was only enabled for some
     backends.   This allows greater accuracy in allowing the database server to
     recognize when a string value is to be interpreted as JSON.

 .. change::
     :tags: bug, orm
     :tickets: 11995

     Refined the check which the ORM lazy loader uses to detect &quot;this would be
     loading by primary key and the primary key is NULL, skip loading&quot; to take
     into account the current setting for the
     :paramref:`.orm.Mapper.allow_partial_pks` parameter. If this parameter is
     ``False``, then a composite PK value that has partial NULL elements should
     also be skipped.   This can apply to some composite overlapping foreign key
     configurations.


 .. change::
     :tags: bug, orm
     :tickets: 11997

     Fixed bug in ORM &quot;update with WHERE clause&quot; feature where an explicit
     ``.returning()`` would interfere with the &quot;fetch&quot; synchronize strategy due
     to an assumption that the ORM mapped class featured the primary key columns
     in a specific position within the RETURNING.  This has been fixed to use
     appropriate ORM column targeting.

 .. change::
     :tags: bug, sql, regression
     :tickets: 12002

     Fixed regression from 1.4 where some datatypes such as those derived from
     :class:`.TypeDecorator` could not be pickled when they were part of a
     larger SQL expression composition due to internal supporting structures
     themselves not being pickleable.

.. changelog::

2.0.35

:released: September 16, 2024

 .. change::
     :tags: bug, orm, typing
     :tickets: 11820

     Fixed issue where it was not possible to use ``typing.Literal`` with
     ``Mapped[]`` on Python 3.8 and 3.9.  Pull request courtesy Frazer McLean.

 .. change::
     :tags: bug, sqlite, regression
     :tickets: 11840

     The changes made for SQLite CHECK constraint reflection in versions 2.0.33
     and 2.0.34 , :ticket:`11832` and :ticket:`11677`, have now been fully
     reverted, as users continued to identify existing use cases that stopped
     working after this change.   For the moment, because SQLite does not
     provide any consistent way of delivering information about CHECK
     constraints, SQLAlchemy is limited in what CHECK constraint syntaxes can be
     reflected, including that a CHECK constraint must be stated all on a
     single, independent line (or inline on a column definition)  without
     newlines, tabs in the constraint definition or unusual characters in the
     constraint name.  Overall, reflection for SQLite is tailored towards being
     able to reflect CREATE TABLE statements that were originally created by
     SQLAlchemy DDL constructs.  Long term work on a DDL parser that does not
     rely upon regular expressions may eventually improve upon this situation.
     A wide range of additional cross-dialect CHECK constraint reflection tests
     have been added as it was also a bug that these changes did not trip any
     existing tests.

 .. change::
     :tags: orm, bug
     :tickets: 11849

     Fixed issue in ORM evaluator where two datatypes being evaluated with the
     SQL concatenator operator would not be checked for
     :class:`.UnevaluatableError` based on their datatype; this missed the case
     of :class:`_postgresql.JSONB` values being used in a concatenate operation
     which is supported by PostgreSQL as well as how SQLAlchemy renders the SQL
     for this operation, but does not work at the Python level. By implementing
     :class:`.UnevaluatableError` for this combination, ORM update statements
     will now fall back to &quot;expire&quot; when a concatenated JSON value used in a SET
     clause is to be synchronized to a Python object.

 .. change::
     :tags: bug, orm
     :tickets: 11853

     An warning is emitted if :func:`_orm.joinedload` or
     :func:`_orm.subqueryload` are used as a top level option against a
     statement that is not a SELECT statement, such as with an
     ``insert().returning()``.   There are no JOINs in INSERT statements nor is
     there a &quot;subquery&quot; that can be repurposed for subquery eager loading, and
     for UPDATE/DELETE joinedload does not support these either, so it is never
     appropriate for this use to pass silently.

 .. change::
     :tags: bug, orm
     :tickets: 11855

     Fixed issue where using loader options such as :func:`_orm.selectinload`
     with additional criteria in combination with ORM DML such as
     :func:`_sql.insert` with RETURNING would not correctly set up internal
     contexts required for caching to work correctly, leading to incorrect
     results.

 .. change::
     :tags: bug, mysql
     :tickets: 11870

     Fixed issue in mariadbconnector dialect where query string arguments that
     weren&#x27;t checked integer or boolean arguments would be ignored, such as
     string arguments like ``unix_socket``, etc.  As part of this change, the
     argument parsing for particular elements such as ``client_flags``,
     ``compress``, ``local_infile`` has been made more consistent across all
     MySQL / MariaDB dialect which accept each argument. Pull request courtesy
     Tobias Alex-Petersen.


.. changelog::

2.0.34

:released: September 4, 2024

 .. change::
     :tags: bug, orm
     :tickets: 11831

     Fixed regression caused by issue :ticket:`11814` which broke support for
     certain flavors of :pep:`593` ``Annotated`` in the type_annotation_map when
     builtin types such as ``list``, ``dict`` were used without an element type.
     While this is an incomplete style of typing, these types nonetheless
     previously would be located in the type_annotation_map correctly.

 .. change::
     :tags: bug, sqlite
     :tickets: 11832

     Fixed regression in SQLite reflection caused by :ticket:`11677` which
     interfered with reflection for CHECK constraints that were followed
     by other kinds of constraints within the same table definition.   Pull
     request courtesy Harutaka Kawamura.


.. changelog::

2.0.33

:released: September 3, 2024

 .. change::
     :tags: bug, sqlite
     :tickets: 11677

     Improvements to the regex used by the SQLite dialect to reflect the name
     and contents of a CHECK constraint.  Constraints with newline, tab, or
     space characters in either or both the constraint text and constraint name
     are now properly reflected.   Pull request courtesy Jeff Horemans.



 .. change::
     :tags: bug, engine
     :tickets: 11687

     Fixed issue in internal reflection cache where particular reflection
     scenarios regarding same-named quoted_name() constructs would not be
     correctly cached.  Pull request courtesy Felix Lüdin.

 .. change::
     :tags: bug, sql, regression
     :tickets: 11703

     Fixed regression in :meth:`_sql.Select.with_statement_hint` and others
     where the generative behavior of the method stopped producing a copy of the
     object.

 .. change::
     :tags: bug, mysql
     :tickets: 11731

     Fixed issue in MySQL dialect where using INSERT..FROM SELECT in combination
     with ON DUPLICATE KEY UPDATE would erroneously render on MySQL 8 and above
     the &quot;AS new&quot; clause, leading to syntax failures.  This clause is required
     on MySQL 8 to follow the VALUES clause if use of the &quot;new&quot; alias is
     present, however is not permitted to follow a FROM SELECT clause.


 .. change::
     :tags: bug, sqlite
     :tickets: 11746

     Improvements to the regex used by the SQLite dialect to reflect the name
     and contents of a UNIQUE constraint that is defined inline within a column
     definition inside of a SQLite CREATE TABLE statement, accommodating for tab
     characters present within the column / constraint line. Pull request
     courtesy John A Stevenson.




 .. change::
     :tags: bug, typing
     :tickets: 11782

     Fixed typing issue with :meth:`_sql.Select.with_only_columns`.

 .. change::
     :tags: bug, orm
     :tickets: 11788

     Correctly cleanup the internal top-level module registry when no
     inner modules or classes are registered into it.

 .. change::
     :tags: bug, schema
     :tickets: 11802

     Fixed bug where the ``metadata`` element of an ``Enum`` datatype would not
     be transferred to the new :class:`.MetaData` object when the type had been
     copied via a :meth:`.Table.to_metadata` operation, leading to inconsistent
     behaviors within create/drop sequences.

 .. change::
     :tags: bug, orm
     :tickets: 11814

     Improvements to the ORM annotated declarative type map lookup dealing with
     composed types such as ``dict[str, Any]`` linking to JSON (or others) with
     or without &quot;future annotations&quot; mode.



 .. change::
     :tags: change, general
     :tickets: 11818

     The pin for ``setuptools&lt;69.3`` in ``pyproject.toml`` has been removed.
     This pin was to prevent a sudden change in setuptools to use :pep:`625`
     from taking place, which would change the file name of SQLAlchemy&#x27;s source
     distribution on pypi to be an all lower case name, which is likely to cause
     problems with various build environments that expected the previous naming
     style.  However, the presence of this pin is holding back environments that
     otherwise want to use a newer setuptools, so we&#x27;ve decided to move forward
     with this change, with the assumption that build environments will have
     largely accommodated the setuptools change by now.



 .. change::
     :tags: bug, postgresql
     :tickets: 11821

     Revising the asyncpg ``terminate()`` fix first made in :ticket:`10717`
     which improved the resiliency of this call under all circumstances, adding
     ``asyncio.CancelledError`` to the list of exceptions that are intercepted
     as failing for a graceful ``.close()`` which will then proceed to call
     ``.terminate()``.

 .. change::
     :tags: bug, mssql
     :tickets: 11822

     Added error &quot;The server failed to resume the transaction&quot; to the list of
     error strings for the pymssql driver in determining a disconnect scenario,
     as observed by one user using pymssql under otherwise unknown conditions as
     leaving an unusable connection in the connection pool which fails to ping
     cleanly.

 .. change::
     :tags: bug, tests

     Added missing ``array_type`` property to the testing suite
     ``SuiteRequirements`` class.

.. changelog::

2.0.32

:released: August 5, 2024

 .. change::
     :tags: bug, examples
     :tickets: 10267

     Fixed issue in history_meta example where the &quot;version&quot; column in the
     versioned table needs to default to the most recent version number in the
     history table on INSERT, to suit the use case of a table where rows are
     deleted, and can then be replaced by new rows that re-use the same primary
     key identity.  This fix adds an additonal SELECT query per INSERT in the
     main table, which may be inefficient; for cases where primary keys are not
     re-used, the default function may be omitted.  Patch courtesy  Philipp H.
     v. Loewenfeld.

 .. change::
     :tags: bug, oracle
     :tickets: 11557

     Fixed table reflection on Oracle 10.2 and older where compression options
     are not supported.

 .. change::
     :tags: oracle, usecase
     :tickets: 10820

     Added API support for server-side cursors for the oracledb async dialect,
     allowing use of the :meth:`_asyncio.AsyncConnection.stream` and similar
     stream methods.

 .. change::
     :tags: bug, orm
     :tickets: 10834

     Fixed issue where using the :meth:`_orm.Query.enable_eagerloads` and
     :meth:`_orm.Query.yield_per` methods at the same time, in order to disable
     eager loading that&#x27;s configured on the mapper directly, would be silently
     ignored, leading to errors or unexpected eager population of attributes.

 .. change::
     :tags: orm
     :tickets: 11163

     Added a warning noting when an
     :meth:`_engine.ConnectionEvents.engine_connect` event may be leaving
     a transaction open, which can alter the behavior of a
     :class:`_orm.Session` using such an engine as bind.
     On SQLAlchemy 2.1 :paramref:`_orm.Session.join_transaction_mode` will
     instead be ignored in all cases when the session bind is
     an :class:`_engine.Engine`.

 .. change::
     :tags: bug, general, regression
     :tickets: 11435

     Restored legacy class names removed from
     ``sqlalalchemy.orm.collections.*``, including
     :class:`_orm.MappedCollection`, :func:`_orm.mapped_collection`,
     :func:`_orm.column_mapped_collection`,
     :func:`_orm.attribute_mapped_collection`. Pull request courtesy Takashi
     Kajinami.

 .. change::
     :tags: bug, sql
     :tickets: 11471

     Follow up of :ticket:`11471` to fix caching issue where using the
     :meth:`.CompoundSelectState.add_cte` method of the
     :class:`.CompoundSelectState` construct would not set a correct cache key
     which distinguished between different CTE expressions. Also added tests

     Fixed issue in MySQL dialect where ENUM values that contained percent signs
     were not properly escaped for the driver.


 .. change::
     :tags: usecase, oracle
     :tickets: 11480

     Implemented two-phase transactions for the oracledb dialect. Historically,
     this feature never worked with the cx_Oracle dialect, however recent
     improvements to the oracledb successor now allow this to be possible.  The
     two phase transaction API is available at the Core level via the
     :meth:`_engine.Connection.begin_twophase` method.

     :tags: bug, postgresql
     :tickets: 11522

     It is now considered a pool-invalidating disconnect event when psycopg2
     throws an &quot;SSL SYSCALL error: Success&quot; error message, which can occur when
     the SSL connection to Postgres is terminated abnormally.

 .. change::
     :tags: bug, schema
     :tickets: 11530

     Fixed additional issues in the event system triggered by unpickling of a
     :class:`.Enum` datatype, continuing from :ticket:`11365` and
     :ticket:`11360`,  where dynamically generated elements of the event
     structure would not be present when unpickling in a new process.

 .. change::
     :tags: bug, engine
     :tickets: 11532

     Fixed issue in &quot;insertmanyvalues&quot; feature where a particular call to
     ``cursor.fetchall()`` were not wrapped in SQLAlchemy&#x27;s exception wrapper,
     which apparently can raise a database exception during fetch when using
     pyodbc.

     :tags: usecase, orm
     :tickets: 11575

     The :paramref:`_orm.aliased.name` parameter to :func:`_orm.aliased` may now
     be combined with the :paramref:`_orm.aliased.flat` parameter, producing
     per-table names based on a name-prefixed naming convention.  Pull request
     courtesy Eric Atkin.

 .. change::
     :tags: bug, postgresql
     :tickets: 11576

     Fixed issue where the :func:`_sql.collate` construct, which explicitly sets
     a collation for a given expression, would maintain collation settings for
     the underlying type object from the expression, causing SQL expressions to
     have both collations stated at once when used in further expressions for
     specific dialects that render explicit type casts, such as that of asyncpg.
     The :func:`_sql.collate` construct now assigns its own type to explicitly
     include the new collation, assuming it&#x27;s a string type.

 .. change::
     :tags: bug, sql
     :tickets: 11592

     Fixed bug where the :meth:`.Operators.nulls_first()` and
     :meth:`.Operators.nulls_last()` modifiers would not be treated the same way
     as :meth:`.Operators.desc()` and :meth:`.Operators.asc()` when determining
     if an ORDER BY should be against a label name already in the statement. All
     four modifiers are now treated the same within ORDER BY.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11625

     Fixed regression appearing in 2.0.21 caused by :ticket:`10279` where using
     a :func:`_sql.delete` or :func:`_sql.update` against an ORM class that is
     the base of an inheritance hierarchy, while also specifying that subclasses
     should be loaded polymorphically, would leak the polymorphic joins into the
     UPDATE or DELETE statement as well creating incorrect SQL.

     :tickets: 11661

     Fixed regression from version 1.4 in
     :meth:`_orm.Session.bulk_insert_mappings` where using the
     :paramref:`_orm.Session.bulk_insert_mappings.return_defaults` parameter
     would not populate the passed in dictionaries with newly generated primary
     key values.


 .. change::
     :tags: bug, oracle, sqlite
     :tickets: 11663

     Implemented bitwise operators for Oracle which was previously
     non-functional due to a non-standard syntax used by this database.
     Oracle&#x27;s support for bitwise &quot;or&quot; and &quot;xor&quot; starts with server version 21.
     Additionally repaired the implementation of &quot;xor&quot; for SQLite.

     As part of this change, the dialect compliance test suite has been enhanced
     to include support for server-side bitwise tests; third party dialect
     authors should refer to new &quot;supports_bitwise&quot; methods in the
     requirements.py file to enable these tests.




 .. change::
     :tags: bug, typing

     Fixed internal typing issues to establish compatibility with mypy 1.11.0.
     Note that this does not include issues which have arisen with the
     deprecated mypy plugin used by SQLAlchemy 1.4-style code; see the addiional
     change note for this plugin indicating revised compatibility.

 .. change::
     :tags: usecase, orm
     :tickets: 11361

     Added missing parameter :paramref:`_orm.with_polymorphic.name` that
     allows specifying the name of returned :class:`_orm.AliasedClass`.

 .. change::
     :tags: bug, orm
     :tickets: 11365

     Fixed issue where a :class:`.MetaData` collection would not be
     serializable, if an :class:`.Enum` or :class:`.Boolean` datatype were
     present which had been adapted. This specific scenario in turn could occur
     when using the :class:`.Enum` or :class:`.Boolean` within ORM Annotated
     Declarative form where type objects frequently get copied.

 .. change::
     :tags: schema, usecase
     :tickets: 11374

     Added :paramref:`_schema.Column.insert_default` as an alias of
     :paramref:`_schema.Column.default` for compatibility with
     :func:`_orm.mapped_column`.

 .. change::
     :tags: bug, general
     :tickets: 11417

     Set up full Python 3.13 support to the extent currently possible, repairing
     issues within internal language helpers as well as the serializer extension
     module.

 .. change::
     :tags: bug, sql

     Fixed issue when serializing an :func:`_sql.over` clause with
     unbounded range or rows.

 .. change::
     :tags: bug, sql
     :tickets: 11423

     Added missing methods :meth:`_sql.FunctionFilter.within_group`
     and :meth:`_sql.WithinGroup.filter`

 .. change::
     :tags: bug, sql
     :tickets: 11426

     Fixed bug in :meth:`_sql.FunctionFilter.filter` that would mutate
     the existing function in-place. It now behaves like the rest of the
     SQLAlchemy API, returning a new instance instead of mutating the
     original one.

 .. change::
     :tags: bug, orm
     :tickets: 11446

     Fixed issue where the :func:`_orm.selectinload` and
     :func:`_orm.subqueryload` loader options would fail to take effect when
     made against an inherited subclass that itself included a subclass-specific
     :paramref:`_orm.Mapper.with_polymorphic` setting.

 .. change::
     :tags: bug, orm
     :tickets: 11449

     Fixed very old issue involving the :paramref:`_orm.joinedload.innerjoin`
     parameter where making use of this parameter mixed into a query that also
     included joined eager loads along a self-referential or other cyclical
     relationship, along with complicating factors like inner joins added for
     secondary tables and such, would have the chance of splicing a particular
     inner join to the wrong part of the query.  Additional state has been added
     to the internal method that does this splice to make a better decision as
     to where splicing should proceed.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11509

     Fixed bug in ORM Declarative where the ``__table__`` directive could not be
     declared as a class function with :func:`_orm.declared_attr` on a
     superclass, including an ``__abstract__`` class as well as coming from the
     declarative base itself.  This was a regression since 1.4 where this was
     working, and there were apparently no tests for this particular use case.

     added ``ParamSpec`` to the asyncio ``run_sync()`` methods, where using
     :meth:`_asyncio.AsyncConnection.run_sync` with

     :tickets: 11210

     Fixed issue in the
     :paramref:`_engine.Connection.execution_options.logging_token` option,
     where changing the value of ``logging_token`` on a connection that has
     already logged messages would not be updated to reflect the new logging
     token.  This in particular prevented the use of
     :meth:`_orm.Session.connection` to change the option on the connection,
     since the BEGIN logging message would already have been emitted.

 .. change::
     :tags: bug, orm
     :tickets: 11220

     Added new attribute :attr:`_orm.ORMExecuteState.is_from_statement` to
     detect statements created using :meth:`_sql.Select.from_statement`, and
     enhanced ``FromStatement`` to set :attr:`_orm.ORMExecuteState.is_select`,
     :attr:`_orm.ORMExecuteState.is_insert`,
     :attr:`_orm.ORMExecuteState.is_update`, and
     :attr:`_orm.ORMExecuteState.is_delete` according to the element that is

     :tags: bug, orm, regression
     :tickets: 11292

     Fixed regression from 1.4 where using :func:`_orm.defaultload` in
     conjunction with a non-propagating loader like :func:`_orm.contains_eager`
     would nonetheless propagate the :func:`_orm.contains_eager` to a lazy load
     operation, causing incorrect queries as this option is only intended to
     come from an original load.

     Fixed issue in cursor handling which affected handling of duplicate
     :class:`_sql.Column` or similar objcts in the columns clause of
     :func:`_sql.select`, both in combination with arbitary :func:`_sql.text()`
     clauses in the SELECT list, as well as when attempting to retrieve
     :meth:`_engine.Result.mappings` for the object, which would lead to an
     internal error.



 .. change::

     :tickets: 11327

     Fixed issue in :func:`_orm.selectin_polymorphic` loader option where the
     SELECT emitted would only accommodate for the child-most class among the
     result rows that were returned, leading intermediary-class attributes to be
     unloaded if there were no concrete instances of that intermediary-class
     present in the result.   This issue only presented itself for multi-level
     inheritance hierarchies.

     Fixed Declarative issue where typing a relationship using

     The PostgreSQL dialect now returns :class:`_postgresql.DOMAIN` instances

 .. change::
     :tags: bug, orm
     :tickets: 11091

     Fixed issue in ORM annotated declarative where using
     :func:`_orm.mapped_column()` with an :paramref:`_orm.mapped_column.index`
     or :paramref:`_orm.mapped_column.unique` setting of False would be
     overridden by an incoming ``Annotated`` element that featured that
     parameter set to ``True``, even though the immediate
     :func:`_orm.mapped_column()` element is more specific and should take
     precedence.  The logic to reconcile the booleans has been enhanced to
     accommodate a local value of ``False`` as still taking precedence over an
     incoming ``True`` value from the annotated element.

 .. change::
     :tags: usecase, orm
     :tickets: 11130

     Added support for the :pep:`695` ``TypeAliasType`` construct as well as the
     python 3.12 native ``type`` keyword to work with ORM Annotated Declarative
     form when using these constructs to link to a :pep:`593` ``Annotated``
     container, allowing the resolution of the ``Annotated`` to proceed when
     these constructs are used in a :class:`_orm.Mapped` typing container.

     Fixed issue in :ref:`engine_insertmanyvalues` feature where using a primary
     key column with an &quot;inline execute&quot; default generator such as an explicit
     :class:`.Sequence` with an explcit schema name, while at the same time
     using the
     :paramref:`_engine.Connection.execution_options.schema_translate_map`
     feature would fail to render the sequence or the parameters properly,
     leading to errors.

 .. change::
     :tags: bug, engine
     :tickets: 11160

     Made a change to the adjustment made in version 2.0.10 for :ticket:`9618`,
     which added the behavior of reconciling RETURNING rows from a bulk INSERT
     to the parameters that were passed to it.  This behavior included a
     comparison of already-DB-converted bound parameter values against returned
     row values that was not always &quot;symmetrical&quot; for SQL column types such as
     UUIDs, depending on specifics of how different DBAPIs receive such values
     versus how they return them, necessitating the need for additional
     &quot;sentinel value resolver&quot; methods on these column types.  Unfortunately
     this broke third party column types such as UUID/GUID types in libraries
     like SQLModel which did not implement this special method, raising an error
     &quot;Can&#x27;t match sentinel values in result set to parameter sets&quot;.  Rather than
     attempt to further explain and document this implementation detail of the
     &quot;insertmanyvalues&quot; feature including a public version of the new
     method, the approach is intead revised to no longer need this extra
     conversion step, and the logic that does the comparison now works on the
     pre-converted bound parameter value compared to the post-result-processed
     value, which should always be of a matching datatype.  In the unusual case
     that a custom SQL column type that also happens to be used in a &quot;sentinel&quot;
     column for bulk INSERT is not receiving and returning the same value type,
     the &quot;Can&#x27;t match&quot; error will be raised, however the mitigation is
     straightforward in that the same Python datatype should be passed as that
     returned.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11173

     Fixed regression from version 2.0.28 caused by the fix for :ticket:`11085`
     where the newer method of adjusting post-cache bound parameter values would
     interefere with the implementation for the :func:`_orm.subqueryload` loader
     option, which has some more legacy patterns in use internally, when
     the additional loader criteria feature were used with this loader option.

 .. change::
     :tags: bug, sql, regression
     :tickets: 11176

     Fixed regression from the 1.4 series where the refactor of the
     :meth:`_types.TypeEngine.with_variant` method introduced at
     :ref:`change_6980` failed to accommodate for the ``.copy()`` method, which
     will lose the variant mappings that are set up. This becomes an issue for
     the very specific case of a &quot;schema&quot; type, which includes types such as
     :class:`.Enum` and :class:`_types.ARRAY`, when they are then used in the context
     of an ORM Declarative mapping with mixins where copying of types comes into
     play.  The variant mapping is now copied as well.

 .. change::
     :tags: bug, tests
     :tickets: 11187

     Backported to SQLAlchemy 2.0 an improvement to the test suite with regards
     to how asyncio related tests are run, now using the newer Python 3.11
     ``asyncio.Runner`` or a backported equivalent, rather than relying on the
     previous implementation based on ``asyncio.get_running_loop()``.  This
     should hopefully prevent issues with large suite runs on CPU loaded
     hardware where the event loop seems to become corrupted, leading to
     cascading failures.


.. changelog::

2.0.28

:released: March 4, 2024

 .. change::
     :tags: engine, usecase
     :tickets: 10974

     Added new core execution option
     :paramref:`_engine.Connection.execution_options.preserve_rowcount`. When
     set, the ``cursor.rowcount`` attribute from the DBAPI cursor will be
     unconditionally memoized at statement execution time, so that whatever
     value the DBAPI offers for any kind of statement will be available using
     the :attr:`_engine.CursorResult.rowcount` attribute from the
     :class:`_engine.CursorResult`.  This allows the rowcount to be accessed for
     statements such as INSERT and SELECT, to the degree supported by the DBAPI
     in use. The :ref:`engine_insertmanyvalues` also supports this option and
     will ensure :attr:`_engine.CursorResult.rowcount` is correctly set for a
     bulk INSERT of rows when set.

 .. change::
     :tags: bug, orm, regression
     :tickets: 11010

     Fixed regression caused by :ticket:`9779` where using the &quot;secondary&quot; table
     in a relationship ``and_()`` expression would fail to be aliased to match
     how the &quot;secondary&quot; table normally renders within a
     :meth:`_sql.Select.join` expression, leading to an invalid query.

 .. change::
     :tags: bug, orm, performance, regression
     :tickets: 11085

     Adjusted the fix made in :ticket:`10570`, released in 2.0.23, where new
     logic was added to reconcile possibly changing bound parameter values
     across cache key generations used within the :func:`_orm.with_expression`
     construct.  The new logic changes the approach by which the new bound
     parameter values are associated with the statement, avoiding the need to
     deep-copy the statement which can result in a significant performance
     penalty for very deep / complex SQL constructs.  The new approach no longer
     requires this deep-copy step.

 .. change::
     :tags: bug, asyncio
     :tickets: 8771

     An error is raised if a :class:`.QueuePool` or other non-asyncio pool class
     is passed to :func:`_asyncio.create_async_engine`.  This engine only
     accepts asyncio-compatible pool classes including
     :class:`.AsyncAdaptedQueuePool`. Other pool classes such as
     :class:`.NullPool` are compatible with both synchronous and asynchronous
     engines as they do not perform any locking.

     element in the &quot;whens&quot; had no type, or in other cases where the type
     could resolve to ``None``.  The logic has been updated to scan all

     :tickets: 10863

     Fixed regression in the asyncpg dialect caused by :ticket:`10717` in
     release 2.0.24 where the change that now attempts to gracefully close the
     asyncpg connection before terminating would not fall back to
     ``terminate()`` for other potential connection-related exceptions other
     than a timeout error, not taking into account cases where the graceful
     ``.close()`` attempt fails for other reasons such as connection errors.


 .. change::
     :tags: oracle, bug, performance
     :tickets: 10877

     Changed the default arraysize of the Oracle dialects so that the value set
     by the driver is used, that is 100 at the time of writing for both
     cx_oracle and oracledb. Previously the value was set to 50 by default. The
     setting of 50 could cause significant performance regressions compared to
     when using cx_oracle/oracledb alone to fetch many hundreds of rows over
     slower networks.

     where the ORM disabled the cache due to a too-deep chain of loader options.
     The condition which this warning highlights is difficult to resolve and is
     generally just a limitation in the ORM&#x27;s application of SQL caching. A
     future feature may include the ability to tune the threshold where caching
     is disabled, but for now the warning will no longer be a nuisance.

     Fixed issue where it was not possible to use a type (such as an enum)
     within a :class:`_orm.Mapped` container type if that type were declared
     locally within the class body.  The scope of locals used for the eval now
     includes that of the class body itself.  In addition, the expression within
     :class:`_orm.Mapped` may also refer to the class name itself, if used as a
     string or with future annotations mode.

     Support the ``USING &lt;method&gt;`` option for PostgreSQL ``CREATE TABLE`` to
     specify the access method to use to store the contents for the new table.

     :tags: bug, examples
     :tickets: 10920

     Fixed regression in history_meta example where the use of
     :meth:`_schema.MetaData.to_metadata` to make a copy of the history table
     would also copy indexes (which is a good thing), but causing naming
     conflicts indexes regardless of naming scheme used for those indexes. A
     &quot;_history&quot; suffix is now added to these indexes in the same way as is
     achieved for the table name.


 .. change::
     :tags: bug, orm
     :tickets: 10967

     Fixed issue where using :meth:`_orm.Session.delete` along with the
     :paramref:`_orm.Mapper.version_id_col` feature would fail to use the
     correct version identifier in the case that an additional UPDATE were
     emitted against the target object as a result of the use of
     :paramref:`_orm.relationship.post_update` on the object.  The issue is
     similar to :ticket:`10800` just fixed in version 2.0.25 for the case of
     updates alone.

 .. change::
     :tags: bug, orm
     :tickets: 10990

     Fixed issue where an assertion within the implementation for
     :func:`_orm.with_expression` would raise if a SQL expression that was not
     cacheable were used; this was a 2.0 regression since 1.4.

 .. change::
     :tags: postgresql, usecase
     :tickets: 9736

     Correctly type PostgreSQL RANGE and MULTIRANGE types as ``Range[T]``
     and ``Sequence[Range[T]]``.
     Introduced utility sequence :class:`_postgresql.MultiRange` to allow better
     interoperability of MULTIRANGE types.

 .. change::
     :tags: postgresql, usecase

     Differentiate between INT4 and INT8 ranges and multi-ranges types when
     inferring the database type from a :class:`_postgresql.Range` or
     :class:`_postgresql.MultiRange` instance, preferring INT4 if the values
     fit into it.

 .. change::
     :tags: bug, typing

     Fixed the type signature for the :meth:`.PoolEvents.checkin` event to
     indicate that the given :class:`.DBAPIConnection` argument may be ``None``
     in the case where the connection has been invalidated.

 .. change::
     :tags: bug, examples

     Fixed the performance example scripts in examples/performance to mostly
     work with the Oracle database, by adding the :class:`.Identity` construct
     to all the tables and allowing primary generation to occur on this backend.
     A few of the &quot;raw DBAPI&quot; cases still are not compatible with Oracle.


 .. change::
     :tags: bug, mssql

     Fixed an issue regarding the use of the :class:`.Uuid` datatype with the
     :paramref:`.Uuid.as_uuid` parameter set to False, when using the pymssql
     dialect. ORM-optimized INSERT statements (e.g. the &quot;insertmanyvalues&quot;
     feature) would not correctly align primary key UUID values for bulk INSERT
     statements, resulting in errors.  Similar issues were fixed for the
     PostgreSQL drivers as well.

2.0.25

:released: January 2, 2024

 .. change::
     :tags: oracle, asyncio
     :tickets: 10679

     Added support for :ref:`oracledb` in asyncio mode, using the newly released
     version of the ``oracledb`` DBAPI that includes asyncio support. For the
     2.0 series, this is a preview release, where the current implementation
     does not yet have include support for
     :meth:`_asyncio.AsyncConnection.stream`. Improved support is planned for
     the 2.1 release of SQLAlchemy.

 .. change::
     :tags: bug, orm
     :tickets: 10800

     Fixed issue where when making use of the
     :paramref:`_orm.relationship.post_update` feature at the same time as using
     a mapper version_id_col could lead to a situation where the second UPDATE
     statement emitted by the post-update feature would fail to make use of the
     correct version identifier, assuming an UPDATE was already emitted in that
     flush which had already bumped the version counter.

 .. change::
     :tags: bug, typing
     :tickets: 10801, 10818

     Fixed regressions caused by typing added to the ``sqlalchemy.sql.functions``
     module in version 2.0.24, as part of :ticket:`6810`:

     * Further enhancements to pep-484 typing to allow SQL functions from
       :attr:`_sql.func` derived elements to work more effectively with ORM-mapped
       attributes (:ticket:`10801`)

     * Fixed the argument types passed to functions so that literal expressions
       like strings and ints are again interpreted correctly (:ticket:`10818`)


 .. change::
     :tags: usecase, orm
     :tickets: 10807

     Added preliminary support for Python 3.12 pep-695 type alias structures,
     when resolving custom type maps for ORM Annotated Declarative mappings.


 .. change::
     :tags: bug, orm
     :tickets: 10815

     Fixed issue where ORM Annotated Declarative would mis-interpret the left
     hand side of a relationship without any collection specified as
     uselist=True if the left type were given as a class and not a string,
     without using future-style annotations.

 .. change::
     :tags: bug, sql
     :tickets: 10817

     Improved compilation of :func:`_sql.any_` / :func:`_sql.all_` in the
     context of a negation of boolean comparison, will now render ``NOT (expr)``
     rather than reversing the equality operator to not equals, allowing
     finer-grained control of negations for these non-typical operators.

.. changelog::

2.0.24

:released: December 28, 2023

 .. change::
     :tags: bug, orm
     :tickets: 10597

     Fixed issue where use of :func:`_orm.foreign` annotation on a
     non-initialized :func:`_orm.mapped_column` construct would produce an
     expression without a type, which was then not updated at initialization
     time of the actual column, leading to issues such as relationships not
     determining ``use_get`` appropriately.


 .. change::
     :tags: bug, schema
     :tickets: 10654

     Fixed issue where error reporting for unexpected schema item when creating
     objects like :class:`_schema.Table` would incorrectly handle an argument
     that was itself passed as a tuple, leading to a formatting error.  The
     error message has been modernized to use f-strings.

 .. change::
     :tags: bug, engine
     :tickets: 10662

     Fixed URL-encoding of the username and password components of
     :class:`.engine.URL` objects when converting them to string using the
     :meth:`_engine.URL.render_as_string` method, by using Python standard
     library ``urllib.parse.quote`` while allowing for plus signs and spaces to
     remain unchanged as supported by SQLAlchemy&#x27;s non-standard URL parsing,
     rather than the legacy home-grown routine from many years ago. Pull request
     courtesy of Xavier NUNN.

 .. change::
     :tags: bug, orm
     :tickets: 10668

     Improved the error message produced when the unit of work process sets the
     value of a primary key column to NULL due to a related object with a
     dependency rule on that column being deleted, to include not just the
     destination object and column name but also the source column from which
     the NULL value is originating.  Pull request courtesy Jan Vollmer.

 .. change::
     :tags: bug, postgresql
     :tickets: 10717

     Adjusted the asyncpg dialect such that when the ``terminate()`` method is
     used to discard an invalidated connection, the dialect will first attempt
     to gracefully close the connection using ``.close()`` with a timeout, if
     the operation is proceeding within an async event loop context only. This
     allows the asyncpg driver to attend to finalizing a ``TimeoutError``
     including being able to close a long-running query server side, which
     otherwise can keep running after the program has exited.

 .. change::
     :tags: bug, orm
     :tickets: 10732

     Modified the ``__init_subclass__()`` method used by
     :class:`_orm.MappedAsDataclass`, :class:`_orm.DeclarativeBase` and
     :class:`_orm.DeclarativeBaseNoMeta` to accept arbitrary ``**kw`` and to
     propagate them to the ``super()`` call, allowing greater flexibility in
     arranging custom superclasses and mixins which make use of
     ``__init_subclass__()`` keyword arguments.  Pull request courtesy Michael
     Oliver.


 .. change::
     :tags: bug, tests
     :tickets: 10747

     Improvements to the test suite to further harden its ability to run
     when Python ``greenlet`` is not installed.   There is now a tox
     target that includes the token &quot;nogreenlet&quot; that will run the suite
     with greenlet not installed (note that it still temporarily installs
     greenlet as part of the tox config, however).

 .. change::
     :tags: bug, sql
     :tickets: 10753

     Fixed issue in stringify for SQL elements, where a specific dialect is not
     passed,  where a dialect-specific element such as the PostgreSQL &quot;on
     conflict do update&quot; construct is encountered and then fails to provide for
     a stringify dialect with the appropriate state to render the construct,
     leading to internal errors.

 .. change::
     :tags: bug, sql

     Fixed issue where stringifying or compiling a :class:`.CTE` that was
     against a DML construct such as an :func:`_sql.insert` construct would fail
     to stringify, due to a mis-detection that the statement overall is an
     INSERT, leading to internal errors.

 .. change::
     :tags: bug, orm
     :tickets: 10776

     Ensured the use case of :class:`.Bundle` objects used in the
     ``returning()`` portion of ORM-enabled INSERT, UPDATE and DELETE statements
     is tested and works fully.   This was never explicitly implemented or
     tested previously and did not work correctly in the 1.4 series; in the 2.0
     series, ORM UPDATE/DELETE with WHERE criteria was missing an implementation
     method preventing :class:`.Bundle` objects from working.

 .. change::
     :tags: bug, orm
     :tickets: 10784

     Fixed 2.0 regression in :class:`.MutableList` where a routine that detects
     sequences would not correctly filter out string or bytes instances, making
     it impossible to assign a string value to a specific index (while
     non-sequence values would work
