failure on Oracle. Oracle's SQL parser does not allow ORDER BY in components of a union in some cases, so xfail this test until an exception can be raised.

2025-10-11Fixed #36646 -- Added compatibility for oracledb 3.4.0.Simon Charette
The Database.Binary, Date, and Timestamp attributes were changed from aliases to bytes, datetime.date, and datetime.datetime to factory functions in oracle/python-oracledb@869a887819cdac7fcd610f9d9d463ade49ea7 which made their usage inadequate for isinstance checks. Thanks John Wagenleitner for the report and Natalia for the triage. Co-authored-by: Mariusz Felisiak <felisiak.mariusz@gmail.com>
2025-09-23Fixed #36616 -- Added DatabaseOperations.adapt_durationfield_value().Tim Graham
2025-09-14Refs #27222 -- Refreshed GeneratedFields values on save() initiated update.Simon Charette
This required implementing UPDATE RETURNING machinery that heavily borrows from the INSERT one.
2025-08-28Refs #27222 -- Adapted RETURNING handling to be usable for UPDATE queries.Simon Charette
Renamed existing methods and abstractions used for INSERT … RETURNING to be generic enough to be used in the context of UPDATEs as well. This also consolidates SQL compliant implementations on BaseDatabaseOperations.
2025-08-12Remove unused OneToOneField from DatabaseWrapper.data_types.Tim Graham
OneToOneField uses the type of the related field.
2025-08-07Fixed #36210, Refs #36181 -- Allowed Subquery usage in further lookups ↵Jacob Walls
against composite pks. Follow-up to 8561100425876bde3be4b2a22324655f74ff9609. Co-authored-by: Simon Charette <charette.s@gmail.com>
2025-07-23Refs #36500 -- Rewrapped long docstrings and block comments via a script.django-bot
Rewrapped long docstrings and block comments to 79 characters + newline using script from https://github.com/medmunds/autofix-w505.
2025-07-23Removed double spaces after periods and within phrases.Sarah Boyce
2025-05-20Fixed #34262 -- Added support for AnyValue for SQLite, MySQL, Oracle, and ↵ontowhee
Postgresql 16+. Thanks Simon Charette for the guidance and review. Thanks Tim Schilling for the documentation review. Thanks David Wobrock for investigation and solution proposals.
2025-05-14Fixed #36085 -- Added JSONField support for negative array indexing on SQLite.savanto
2025-04-30Refs #36052, #32234 -- Removed create_test_table_with_composite_primary_key ↵Simon Charette
flag in favor of using CompositePrimaryKey. Now that Django properly supports creating models with composite primary keys, the tests should use a `CompositePrimaryKey` field instead of a feature flag to inline backend specific SQL for creating a composite PK. Specifcially, the inspectdb's test_composite_primary_key was adjusted to use schema editor instead of per-backend raw SQL.

2025-03-09Fixed #35487 -- Removed CASCADE from RemoveField() on PostgreSQL.petr.prikryl

2025-03-03Fixed #35444 -- Added generic support for Aggregate.order_by.Chris Muthig
This moves the behaviors of `order_by` used in Postgres aggregates into the `Aggregate` class. This allows for creating aggregate functions that support this behavior across all database engines. This is shown by moving the `StringAgg` class into the shared `aggregates` module and adding support for all databases. The Postgres `StringAgg` class is now a thin wrapper on the new shared `StringAgg` class. Thank you Simon Charette for the review.
2025-02-09Fixed #36148 -- Enabled native tuple comparison lookups on SQLite 3.37+ and ↵Simon Charette
Oracle 23.4+. VALUES must be explicitly specified when declaring a sequence of tuples on SQLite < 3.37 but it's not required on >= 3.37. See sqlite/sqlite@9289f51 which addressed the last remaining issue with IN.
2025-02-09Refs #36148 -- Relied on a feature switch to define tuple lookups support.Simon Charette
This should allow backends more easily opt-in or out of native support and rely on the fallback if unavailable.

max_batch_size. Co-authored-by: Simon Charette <charette.s@gmail.com>

2024-09-09Refs #33817 -- Corrected errors raised when Oracle driver is not installed.Mariusz Felisiak
oracledb_any should reraise ImportError instead of raising ImproperlyConfigured.
2024-08-13Fixed #35665 -- Fixed a crash when passing an empty order_by to Window.Simon Charette
This also caused un-ordered sliced prefetches to crash as they rely on Window. Regression in e16d0c176e9b89628cdec5e58c418378c4a2436a that made OrderByList piggy-back ExpressionList without porting the empty handling that the latter provided. Supporting explicit empty ordering on Window functions and slicing is arguably a foot-gun design due to how backends will return undeterministic results but this is a problem that requires a larger discussion. Refs #35064. Thanks Andrew Backer for the report and Mariusz for the review.
2024-08-03Fixed #35655 -- Reverted "Fixed #35295 -- Used INSERT with multiple rows on ↵Sarah Boyce
Oracle 23c." This reverts commit 175b04942afaff978013db61495f3b39ea12989b due to a crash when Oracle > 23.3.
2024-04-15Fixed ↵Mariusz Felisiak
backends.oracle.tests.TransactionalTests.test_hidden_no_data_found_exception() on oracledb >= 2.1.2. python-oracledb 2.1.2+ no longer hides 'ORA-1403: no data found' exceptions raised in database triggers: https://github.com/oracle/python-oracledb/issues/321
2024-04-02Fixed #35336 -- Addressed crash when adding a GeneratedField with % literals.Simon Charette
A longer term solution is likely to have a better separation of parametrized DDL altogether to handle checks, constraints, defaults, and generated fields but such a change would require a significant refactor that isn't suitable for a backport. Thanks Adrian Garcia for the report.
