Thanks Lily for the review.
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>

2019-01-30Refs #29444 -- Renamed DatabaseFeatures.can_return_id* to be generic for ↵Johannes Hoppe
other columns.
2018-10-17Fixed #21171 -- Avoided starting a transaction when a single (or atomic ↵Florian Apolloner
queries) are executed. Checked the following locations: * Model.save(): If there are parents involved, take the safe way and use transactions since this should be an all or nothing operation. If the model has no parents: * Signals are executed before and after the previous existing transaction -- they were never been part of the transaction. * if `force_insert` is set then only one query is executed -> atomic by definition and no transaction needed. * same applies to `force_update`. * If a primary key is set and no `force_*` is set Django will try an UPDATE and if that returns zero rows it tries an INSERT. The first case is completly save (single query). In the second case a transaction should not produce different results since the update query is basically a no-op then (might miss something though). * QuerySet.update(): no signals issued, single query -> no transaction needed. * Model/Collector.delete(): This one is fun due to the fact that is does many things at once. Most importantly though: It does send signals as part of the transaction, so for maximum backwards compatibility we need to be conservative. To ensure maximum compatibility the transaction here is removed only if the following holds true: * A single instance is being deleted. * There are no signal handlers attached to that instance. * There are no deletions/updates to cascade. * There are no parents which also need deletion.

Oracle. Thanks Shane Allgeier for the report and Tim Graham for the review.
2017-12-20Fixed #28932 -- Prevented Oracle from truncating trailing zeros in the ↵Sergey Fedoseev
fractional part of DecimalField. Fixes the test added in 6fd6d8383f48ea2fe4e058725fa30529a083e9a5. Regression in 7c1f3901bcdabb1340a621e7df9b24f3acd0d6f3.
2017-12-20Fixed #28934 -- Prevented Cast from truncating microseconds on Oracle.Mariusz Felisiak

2017-12-04Fixed #28860 -- Removed unnecessary len() calls.Дилян Палаузов
2017-09-05Removed useless condition from Oracle's NullBooleanField's check constraint.Mariusz Felisiak
NULL cannot be compare with standard operators on Oracle, it works only with IS NULL and IS NOT NULL operators. Therefore 'OR ... IS NULL' condition in NullBooleanField's check constraint is redundant. Nullability is checked in a separate constraint.
2017-08-07Removed unnecessary assignment in Oracle's ↵Srinivas Reddy Thatiparthy
FormatStylePlaceholderCursor._fix_for_params(). Obsolete since fae56427e1987ff8c8bd24d6331007f9c53e7abc.
