delta/python-packages/sqlalchemy.git/lib/sqlalchemy/sql/functions.py, branch pr/201

- add a postgresql-specific form of array_agg() that injects the

2015-08-27T15:22:05+00:00

ARRAY type, references #3132

- Added support for "set-aggregate" functions of the form

2015-08-26T21:19:27+00:00

`` WITHIN GROUP (ORDER BY )``, 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.

- Added support for the SQL-standard function :class:`.array_agg`,

2015-08-26T19:15:55+00:00

which automatically returns an :class:`.Array` of the correct type
and supports index / slice operations.   As arrays are only
supported on Postgresql at the moment, only actually works on
Postgresql. fixes #3132

- build out a new base type for Array, as well as new any/all operators

2015-08-25T22:24:46+00:00

- any/all work for Array as well as subqueries, accepted by MySQL
- Postgresql ARRAY now subclasses Array
- fixes #3516

- Added a supported :meth:`.FunctionElement.alias` method to functions,

2014-07-24T18:33:50+00:00

e.g. the ``func`` construct.  Previously, behavior for this method
was undefined.  The current behavior mimics that of pre-0.9.4,
which is that the function is turned into a single-column FROM
clause with the given alias name, where the column itself is
anonymously named.
fixes #3137
