d-d �� Z d.d �Z!y )/�Rowa Represent a single result row.
The :class:`.Row` object represents a row of a database result. It is
typically associated in the 1.x series of SQLAlchemy with the
:class:`_engine.CursorResult` object, however is also used by the ORM for
tuple-like results as of SQLAlchemy 1.4.
The :class:`.Row` object seeks to act as much like a Python named
tuple as possible. For mapping (i.e. dictionary) behavior on a row,
such as testing for containment of keys, refer to the :attr:`.Row._mapping`
attribute.
.. seealso::
:ref:`tutorial_selecting_data` - includes examples of selecting
rows from SELECT statements.
.. versionchanged:: 1.4
Renamed ``RowProxy`` to :class:`.Row`. :class:`.Row` is no longer a
"proxy" object in that it contains the final form of data within it,
and now acts mostly like a named tuple. Mapping-like functionality is
moved to the :attr:`.Row._mapping` attribute. See
:ref:`change_4710_core` for background on this change.

already a named tuple. However, at the typing level, if this

�Zdd �Zy )r8 a� A ``Mapping`` that maps column names and objects to :class:`.Row`
values.
The :class:`.RowMapping` is available from a :class:`.Row` via the
:attr:`.Row._mapping` attribute, as well as from the iterable interface
provided by the :class:`.MappingResult` object returned by the
:meth:`_engine.Result.mappings` method.
:class:`.RowMapping` supplies Python mapping (i.e. dictionary) access to
the contents of the row. This includes support for testing of
containment of specific keys (string column names or objects), as well
as iteration of keys, values, and items::
for row in result:
if "a" in row._mapping:
print("Column 'a': %s" % row._mapping["a"])
print("Column b: %s" % row._mapping[table.c.b])
.. versionadded:: 1.4 The :class:`.RowMapping` object replaces the
mapping-like access previously provided by a database result row,
which now seeks to behave mostly like a named tuple.
