* Repair reduction in OverMike Bayer2020-10-121-0/+15
| | | | | | | | Fixed issue where a plain pickle dumps call of the :class:`_sql.Over` construct didn't work. Fixes: #5644 Change-Id: I4b07f74ecd5d52f0794128585367012200a38a36

* Create a framework to allow all SQLALCHEMY_WARN_20 to passMike Bayer2020-09-161-18/+15
| | | | | | | | | | | | | | | | | | | | | As the test suite has widespread use of many patterns that are deprecated, enable SQLALCHEMY_WARN_20 globally for the test suite but then break the warnings filter out into a whole list of all the individual warnings we are looking for. this way individual changesets can target a specific class of warning, as many of these warnings will indivdidually affect dozens of files and potentially hundreds of lines of code. Many warnings are also resolved here as this patch started out that way. From this point forward there should be changesets that target a subset of the warnings at a time. For expediency, updates some migration 2.0 docs for ORM as well. Change-Id: I98b8defdf7c37b818b3824d02f7668e3f5f31c94

* | Update select usage to use the new 1.4 formatFederico Caselli2020-09-081-81/+59
|/ | | | | | | | | | | | | | | | This change includes mainly that the bracketed use within select() is moved to positional, and keyword arguments are removed from calls to the select() function. it does not yet fully address other issues such as keyword arguments passed to the table.select(). Additionally, allows False / None to both be considered as "disable" for all of select.correlate(), select.correlate_except(), query.correlate(), which establishes consistency with passing of ``False`` for the legact select(correlate=False) argument.

* | Default psycopg2 executemany mode to "values_only"Mike Bayer2020-06-251-1/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The psycopg2 dialect now defaults to using the very performant ``execute_values()`` psycopg2 extension for compiled INSERT statements, and also impements RETURNING support when this extension is used. This allows INSERT statements that even include an autoincremented SERIAL or IDENTITY value to run very fast while still being able to return the newly generated primary key values. The ORM will then integrate this new feature in a separate change. Implements RETURNING for insert with executemany Adds support to return_defaults() mode and inserted_primary_key to support mutiple INSERTed rows, via return_defauls_rows and inserted_primary_key_rows accessors. within default execution context, new cached compiler getters are used to fetch primary keys from rows inserted_primary_key now returns a plain tuple. this is not yet a row-like object however this can be added. Adds distinct "values_only" and "batch" modes, as "values" has a lot of benefits but "batch" breaks cursor.rowcount psycopg2 minimum version 2.7 so we can remove the large number of checks for very old versions of psycopg2 simplify tests to no longer distinguish between native and non-native json Fixes: #5401 Change-Id: Ic08fd3423d4c5d16ca50994460c0c234868bd61c
* Add support for "real" sequences in mssqlGord Thompson2020-05-291-2/+2
| | | | | | | | | | | | | | | | | Added support for "CREATE SEQUENCE" and full :class:`.Sequence` support for Microsoft SQL Server. This removes the deprecated feature of using :class:`.Sequence` objects to manipulate IDENTITY characteristics which should now be performed using ``mssql_identity_start`` and ``mssql_identity_increment`` as documented at :ref:`mssql_identity`. The change includes a new parameter :paramref:`.Sequence.data_type` to accommodate SQL Server's choice of datatype, which for that backend includes INTEGER and BIGINT. The default starting value for SQL Server's version of :class:`.Sequence` has been set at 1; this default is now emitted within the CREATE SEQUENCE DDL for all backends.

* Try to measure new style caching in the ORM, take twoMike Bayer2020-04-011-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Supercedes: If78fbb557c6f2cae637799c3fec2cbc5ac248aaf Trying to see if by making the cache key memoized, we still can have the older "identity" form of caching which is the cheapest of all, at the same time as the newer "cache key each time" version that is not nearly as cheap; but still much cheaper than no caching at all. Also needed is a per-execution update of _keymap when we invoke from a cached select, so that Column objects that are anonymous or otherwise adapted will match up. this is analogous to the adaption of bound parameters from the cache key. Adds test coverage for the keymap / construct_params() changes related to caching. Also hones performance to a large extent for statement construction and cache key generation. Also includes a new memoized attribute approach that vastly simplifies the previous approach of "group_expirable_memoized_property" and finally integrates cleanly with _clone(), _generate(), etc. no more hardcoding of attributes is needed, as well as that most _reset_memoization() calls are no longer needed as the reset is inherent in a _generate() call; this also has dramatic performance improvements.

* Result initial introductionMike Bayer2020-02-211-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on cc718cccc0bf8a01abdf4068c7ea4f3 which moved RowProxy to Row, allowing Row to be more like a named tuple. - KeyedTuple in ORM is replaced with Row - ResultSetMetaData broken out into "simple" and "cursor" versions for ORM and Core, as well as LegacyCursor version. - Row now has _mapping attribute that supplies full mapping behavior. Row and SimpleRow both have named tuple behavior otherwise. LegacyRow has some mapping features on the tuple which emit deprecation warnings (e.g. keys(), values(), etc). the biggest change for mapping->tuple is the behavior of __contains__ which moves from testing of "key in row" to "value in row". - ResultProxy breaks into ResultProxy and FutureResult (interim), the latter has the newer APIs. Made available to dialects using execution options. - internal reflection methods and most tests move off of implicit Row mapping behavior and move to row._mapping, result.mappings() method using future result - a new strategy system for cursor handling replaces the various subclasses of RowProxy - some execution context adjustments. We will leave EC in but refined things like get_result_proxy() and out parameter handling. Dialects for 1.4 will need to adjust from get_result_proxy() to get_result_cursor_strategy(), if they are using this method - out parameter handling now accommodated by get_out_parameter_values() EC method. Oracle changes for this. external dialect for DB2 for example will also need to adjust for this. - deprecate case_insensitive flag for engine / result, this feature is not used mapping-methods on Row are deprecated, and replaced with Row._mapping.<meth>, including: row.keys() -> use row._mapping.keys() row.items() -> use row._mapping.items() row.values() -> use row._mapping.values() key in row -> use key in row._mapping int in row -> use int < len(row) Fixes: #4710 Fixes: #4878 Change-Id: Ieb9085e9bcff564359095b754da9ae0af55679f0
* Support GenericFunction.name passed as a quoted_nameMike Bayer2020-01-061-0/+16
| | | | | | | | | | | | | | | A function created using :class:`.GenericFunction` can now specify that the name of the function should be rendered with or without quotes by assigning the :class:`.quoted_name` construct to the .name element of the object. Prior to 1.3.4, quoting was never applied to function names, and some quoting was introduced in :ticket:`4467` but no means to force quoting for a mixed case name was available. Additionally, the :class:`.quoted_name` construct when used as the name will properly register its lowercase name in the function registry so that the name continues to be available via the ``func.`` registry. Fixes: #5079 Change-Id: I0653ab8b16e75e628ce82dbbc3d0f77f8336c407
* Add result map targeting for custom compiled, text objectsMike Bayer2019-10-071-0/+15
| | | | | | | | | | | | | | | | In order for text(), custom compiled objects, etc. to be usable by Query(), they are all targeted by object key in the result map. As we no longer want Query to implicitly label these, as well as that text() has no label feature, support adding entries to the result map that have no name, key, or type, only the object itself, and then ensure that the compiler sets up for positional targeting when this condition is detected. Allows for more flexible ORM query usage with custom expressions and text() while having less special logic in query itself. Fixes: #4887 Change-Id: Ie073da127d292d43cb132a2b31bc90af88bfe2fd
* self_group() for FunctionFilterMike Bayer2019-07-121-0/+9

* SelectBase no longer a FromClauseMike Bayer2019-07-061-15/+17
| | | | | | | | | | | | | | | | | | | | As part of the SQLAlchemy 2.0 migration project, a conceptual change has been made to the role of the :class:`.SelectBase` class hierarchy, which is the root of all "SELECT" statement constructs, in that they no longer serve directly as FROM clauses, that is, they no longer subclass :class:`.FromClause`. For end users, the change mostly means that any placement of a :func:`.select` construct in the FROM clause of another :func:`.select` requires first that it be wrapped in a subquery first, which historically is through the use of the :meth:`.SelectBase.alias` method, and is now also available through the use of :meth:`.SelectBase.subquery`. This was usually a requirement in any case since several databases don't accept unnamed SELECT subqueries in their FROM clause in any case. See the documentation in this change for lots more detail. Fixes: #4617 Change-Id: I0f6174ee24b9a1a4529168e52e855e12abd60667

* Make the GenericFunction registry fully case insensitiveMike Bayer2019-04-301-4/+22
| | | | | | | | | | | | Registered function names based on :class:`.GenericFunction` are now retrieved in a case-insensitive fashion in all cases, removing the deprecation logic from 1.3 which temporarily allowed multiple :class:`.GenericFunction` objects to exist with differing cases. A :class:`.GenericFunction` that replaces another on the same name whether or not it's case sensitive emits a warning before replacing the object. Fixes: #4649 Change-Id: I265ae19833132db07ed5b5ae40c4d24f659b1ab3
* Add case insensitivity feature to GenericFunction.Adrien Berchet2019-04-291-3/+55
| | | | | | | | | | | | | | | | | | | | | The :class:`.GenericFunction` namespace is being migrated so that function names are looked up in a case-insensitive manner, as SQL functions do not collide on case sensitive differences nor is this something which would occur with user-defined functions or stored procedures. Lookups for functions declared with :class:`.GenericFunction` now use a case insensitive scheme, however a deprecation case is supported which allows two or more :class:`.GenericFunction` objects with the same name of different cases to exist, which will cause case sensitive lookups to occur for that particular name, while emitting a warning at function registration time. Thanks to Adrien Berchet for a lot of work on this complicated feature. Fixes: #4569 Closes: #4570 Pull-request: https://github.com/sqlalchemy/sqlalchemy/pull/4570 Pull-request-sha: 37d4f3322b6bace88c99b959cb1916dbbc57610e Change-Id: Ief07c6eb55bf398f6aad85b60ef13ee6d1173109
* Remove all remaining text() coercions and ensure identifiers are safeMike Bayer2019-02-061-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fully removed the behavior of strings passed directly as components of a :func:`.select` or :class:`.Query` object being coerced to :func:`.text` constructs automatically; the warning that has been emitted is now an ArgumentError or in the case of order_by() / group_by() a CompileError. This has emitted a warning since version 1.0 however its presence continues to create concerns for the potential of mis-use of this behavior. Note that public CVEs have been posted for order_by() / group_by() which are resolved by this commit: CVE-2019-7164 CVE-2019-7548 Added "SQL phrase validation" to key DDL phrases that are accepted as plain strings, including :paramref:`.ForeignKeyConstraint.on_delete`, :paramref:`.ForeignKeyConstraint.on_update`, :paramref:`.ExcludeConstraint.using`, :paramref:`.ForeignKeyConstraint.initially`, for areas where a series of SQL keywords only are expected.Any non-space characters that suggest the phrase would need to be quoted will raise a :class:`.CompileError`. This change is related to the series of changes committed as part of :ticket:`4481`. Fixed issue where using an uppercase name for an index type (e.g. GIST, BTREE, etc. ) or an EXCLUDE constraint would treat it as an identifier to be quoted, rather than rendering it as is. The new behavior converts these types to lowercase and ensures they contain only valid SQL characters. Quoting is applied to :class:`.Function` names, those which are usually but not necessarily generated from the :attr:`.sql.func` construct, at compile time if they contain illegal characters, such as spaces or punctuation. The names are as before treated as case insensitive however, meaning if the names contain uppercase or mixed case characters, that alone does not trigger quoting. The case insensitivity is currently maintained for backwards compatibility. Fixes: #4481 Fixes: #4473 Fixes: #4467 Change-Id: Ib22a27d62930e24702e2f0f7c74a0473385a08eb

* Allow optional *args with base AnsiFunctionMike Bayer2018-11-291-18/+15
| | | | | | | | | | | | | Amended the :class:`.AnsiFunction` class, the base of common SQL functions like ``CURRENT_TIMESTAMP``, to accept positional arguments like a regular ad-hoc function. This to suit the case that many of these functions on specific backends accept arguments such as "fractional seconds" precision and such. If the function is created with arguments, it renders the the parenthesis and the arguments. If no arguents are present, the compiler generates the non-parenthesized form.

* - Added :class:`.mysql.JSON` for MySQL 5.7. The JSON type providesMike Bayer2016-01-061-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | persistence of JSON values in MySQL as well as basic operator support of "getitem" and "getpath", making use of the ``JSON_EXTRACT`` function in order to refer to individual paths in a JSON structure. fixes #3547 - Added a new type to core :class:`.types.JSON`. This is the base of the PostgreSQL :class:`.postgresql.JSON` type as well as that of the new :class:`.mysql.JSON` type, so that a PG/MySQL-agnostic JSON column may be used. The type features basic index and path searching support. fixes #3619 - reorganization of migration docs etc. to try to refer both to the fixes to JSON that helps Postgresql while at the same time indicating these are new features of the new base JSON type. - a rework of the Array/Indexable system some more, moving things that are specific to Array out of Indexable. - new operators for JSON indexing added to core so that these can be compiled by the PG and MySQL dialects individually - rename sqltypes.Array to sqltypes.ARRAY - as there is no generic Array implementation, this is an uppercase type for now, consistent with the new sqltypes.JSON type that is also not a generic implementation. There may need to be some convention change to handle the case of datatypes that aren't generic, rely upon DB-native implementations, but aren't necessarily all named the same thing.
* - Added support for "set-aggregate" functions of the formticket_3516Mike Bayer2015-08-261-15/+110
| | | | | | | | | | | ``<function> WITHIN GROUP (ORDER BY <criteria>)``, using the method :class:`.FunctionElement.within_group`. A series of common set-aggregate functions with return types derived from the set have been added. This includes functions like :class:`.percentile_cont`, :class:`.dense_rank` and others. fixes #1370 - make sure we use func.name for all _literal_as_binds in functions.py so we get consistent naming behavior for parameters.

* - The :func:`~.expression.column` and :func:`~.expression.table`Mike Bayer2014-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | constructs are now importable from the "from sqlalchemy" namespace, just like every other Core construct. - The implicit conversion of strings to :func:`.text` constructs when passed to most builder methods of :func:`.select` as well as :class:`.Query` now emits a warning with just the plain string sent. The textual conversion still proceeds normally, however. The only method that accepts a string without a warning are the "label reference" methods like order_by(), group_by(); these functions will now at compile time attempt to resolve a single string argument to a column or label expression present in the selectable; if none is located, the expression still renders, but you get the warning again. The rationale here is that the implicit conversion from string to text is more unexpected than not these days, and it is better that the user send more direction to the Core / ORM when passing a raw string as to what direction should be taken. Core/ORM tutorials have been updated to go more in depth as to how text is handled. fixes #2992
* - Added a supported :meth:`.FunctionElement.alias` method to functions,Mike Bayer2014-07-241-0/+51

* - Support has been added for pytest to run tests. This runnerMike Bayer2014-03-031-12/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | is currently being supported in addition to nose, and will likely be preferred to nose going forward. The nose plugin system used by SQLAlchemy has been split out so that it works under pytest as well. There are no plans to drop support for nose at the moment and we hope that the test suite itself can continue to remain as agnostic of testing platform as possible. See the file README.unittests.rst for updated information on running tests with pytest. The test plugin system has also been enhanced to support running tests against mutiple database URLs at once, by specifying the ``--db`` and/or ``--dburi`` flags multiple times. This does not run the entire test suite for each database, but instead allows test cases that are specific to certain backends make use of that backend as the test is run. When using pytest as the test runner, the system will also run specific test suites multiple times, once for each database, particularly those tests within the "dialect suite". The plan is that the enhanced system will also be used by Alembic, and allow Alembic to run migration operation tests against multiple backends in one run, including third-party backends not included within Alembic itself. Third party dialects and extensions are also encouraged to standardize on SQLAlchemy's test suite as a basis; see the file README.dialects.rst for background on building out from SQLAlchemy's test platform.
