Release notes

Sourced from sqlalchemy's releases.

2.0.30

Released: May 5, 2024

orm

• [orm] [bug] Added new attribute _orm.ORMExecuteState.is_from_statement to detect statements created using _sql.Select.from_statement(), and enhanced FromStatement to set _orm.ORMExecuteState.is_select, _orm.ORMExecuteState.is_insert, _orm.ORMExecuteState.is_update, and _orm.ORMExecuteState.is_delete according to the element that is sent to the _sql.Select.from_statement() method itself.

• [orm] [bug] Fixed issue in _orm.selectin_polymorphic() loader option where attributes defined with _orm.composite() on a superclass would cause an internal exception on load.

  References: #11291

• [orm] [bug] [regression] Fixed regression from 1.4 where using _orm.defaultload() in conjunction with a non-propagating loader like _orm.contains_eager() would nonetheless propagate the _orm.contains_eager() to a lazy load operation, causing incorrect queries as this option is only intended to come from an original load.

  References: #11292

• [orm] [bug] Fixed issue in ORM Annotated Declarative where typing issue where literals defined using PEP 695 type aliases would not work with inference of Enum datatypes. Pull request courtesy of Alc-Alc.

  References: #11305

• [orm] [bug] Fixed issue in _orm.selectin_polymorphic() loader option where the SELECT emitted would only accommodate for the child-most class among the result rows that were returned, leading intermediary-class attributes to be unloaded if there were no concrete instances of that intermediary-class present in the result. This issue only presented itself for multi-level inheritance hierarchies.

  References: #11327

• [orm] [bug] Fixed issue in _orm.Session.bulk_save_objects() where the form of the identity key produced when using return_defaults=True would be incorrect. This could lead to an errors during pickling as well as identity map mismatches.
