sqlalchemy.orm.query

module documentation

(source)

The Query class and support. Defines the :class:`_query.Query` class, the central construct used by the ORM to construct database queries. The :class:`_query.Query` class should not be confused with the :class:`_expression.Select` class, which defines database SELECT operations at the SQL (non-ORM) level. ``Query`` differs from ``Select`` in that it returns ORM-mapped objects and interacts with an ORM session, whereas the ``Select`` construct interacts directly with the database to return iterable result sets.
