Tom Carrick 278b6187d2 Refs #21181 -- Corrected DatabaseFeatures.test_collations for Swedish collation.

Petr Čermák fc1446073e Fixed #31987 -- Fixed Cast() with DurationField on MySQL. 2020-09-09 07:01:18 +02:00
Simon Charette f6405c0b8e Fixed #31965 -- Adjusted multi-table fast-deletion on MySQL/MariaDB. 
The optimization introduced in 7acef095d7 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.

Mariusz Felisiak f97f71f592 Refs #12990 -- Bumped mysqlclient requirement to >= 1.4.0. 
MySQLdb.constants.FIELD_TYPE.JSON was added in mysqlclient 1.4.0rc2.

Jon Dufresne 75410228df Fixed #31473 -- Made sql_flush() use RESTART IDENTITY to reset sequences on PostgreSQL. 
The sql_flush() positional argument sequences is replaced by the boolean
keyword-only argument reset_sequences. This ensures that the old
function signature can't be used by mistake when upgrading Django. When
the new argument is True, the sequences of the truncated tables will
reset. Using a single boolean value, rather than a list, allows making a
binary yes/no choice as to whether to reset all sequences rather than a
working on a completely different set.

Adam Johnson 5b884d45ac Fixed #29501 -- Allowed dbshell to pass options to underlying tool. 2020-04-14 14:02:51 +01:00
Mariusz Felisiak 9cab261427
Refs #31411 -- Used RENAME COLUMN on MySQL 8.0.4+. 
MySQL 8.0.3 added support for this syntax but also imposed a
restriction against ALTER TABLE RENAME on tables in a foreign key
relationship if a LOCK TABLES was active which has been lifted in MySQL
8.0.4+.

Mariusz Felisiak 6e026aec5f
Refs #29548 -- Mentioned MariaDB in database system checks. 2020-03-19 09:42:04 +01:00
Simon Charette 9f07f27124 Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL. 
Both backends order NULLs first on ascending ordering and last on
descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when
asc(nulls_first) and desc(nulls_last) are used since it prevents indice
usage.

Jon Dufresne 3259983f56 Fixed #31233 -- Closed database connections and cursors after use. 2020-02-06 15:35:23 +01:00
Jon Dufresne f48f671223 Refs #31233 -- Changed DatabaseWrapper._nodb_connection to _nodb_cursor(). 
It is now a method instead of a property and returns a context manager
that yields a cursor on entry and closes the cursor and connection upon
exit.
 2020-02-06 15:29:38 +01:00
Nick Pope 335c9c94ac Simplified imports from django.db and django.contrib.gis.db. 2020-02-04 13:20:06 +01:00

Simon Charette 9bcbcd599a Fixed #31133 -- Fixed crash when subtracting against a subquery annotation. 
The subtract_temporals() database operation was not handling expressions
returning SQL params in mixed database types.

Regression in 3543129822.

Thanks Reupen Shah for the report.

Fixed DatabaseFeatures.has_select_for_update_nowait on MariaDB 10.3+. 
Thanks Kola Erinoso for the report.
 2019-11-05 10:18:47 +01:00
Nick Pope 7286eaf681 Refs #13312 -- Simplified handling of nulls ordering on MySQL. 
MySQL & MariaDB support the standard IS NULL and IS NOT NULL so
the same workaround used for NULLS FIRST and NULLS LAST that is
used for SQLite < 3.30.0 can be used.

Thanks Simon Charette for the discussion.

Simon Charette 7acef095d7 Fixed #23576 -- Implemented multi-alias fast-path deletion in MySQL backend. 
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.
