* Refs #33374 -- Adjusted full match condition handling.Simon Charette2022-11-071-5/+9
| | | | | | Adjusting WhereNode.as_sql() to raise an exception when encoutering a full match just like with empty matches ensures that all case are explicitly handled.
* Refs #28333 -- Added partial support for filtering against window functions.Simon Charette2022-08-151-4/+7
| | | | | | | | | | | | | | | | | | | | Adds support for joint predicates against window annotations through subquery wrapping while maintaining errors for disjointed filter attempts. The "qualify" wording was used to refer to predicates against window annotations as it's the name of a specialized Snowflake extension to SQL that is to window functions what HAVING is to aggregates. While not complete the implementation should cover most of the common use cases for filtering against window functions without requiring the complex subquery pushdown and predicate re-aliasing machinery to deal with disjointed predicates against columns, aggregates, and window functions. A complete disjointed filtering implementation should likely be deferred until proper QUALIFY support lands or the ORM gains a proper subquery pushdown interface.

* Fixed #32645 -- Fixed QuerySet.update() crash when ordered by joined fields ↵Mariusz Felisiak2021-04-141-1/+10
| | | | | | | on MySQL/MariaDB. Thanks Matt Westcott for the report. Regression in 779e615e362108862f1681f965ee9e4f1d0ae6d2.
* Fixed #31965 -- Adjusted multi-table fast-deletion on MySQL/MariaDB.Simon Charette2020-08-311-10/+12
| | | | | | | | | | | | | The optimization introduced in 7acef095d73 did not properly handle deletion involving filters against aggregate annotations. It initially was surfaced by a MariaDB test failure but misattributed to an undocumented change in behavior that resulted in the systemic generation of poorly performing database queries in 5b83bae031. Thanks Anton Plotkin for the report. Refs #23576.

* Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend.Simon Charette2019-10-241-1/+19
| | | | | | | | | This required moving the entirety of DELETE SQL generation to the compiler where it should have been in the first place and implementing a specialized compiler on MySQL/MariaDB. The MySQL compiler relies on the "DELETE table FROM table JOIN" syntax for queries spanning over multiple tables.
* Fixed #23867 -- removed DateQuerySet hacksAnssi Kääriäinen2014-11-261-8/+0
| | | | | | The .dates() queries were implemented by using custom Query, QuerySet, and Compiler classes. Instead implement them by using expressions and database converters APIs.

* Fixed #18757, #14462, #21565 -- Reworked database-python type conversionsMarc Tamlyn2014-09-031-11/+0
| | | | | | | | | | | | Complete rework of translating data values from database Deprecation of SubfieldBase, removal of resolve_columns and convert_values in favour of a more general converter based approach and public API Field.from_db_value(). Now works seamlessly with aggregation, .values() and raw queries. Thanks to akaariai in particular for extensive advice and inspiration, also to shaib, manfre and timograham for their reviews.
