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. � c � � t d� �)Nzcan't set attribute��AttributeError)�self�name�values �F/opt/hc_python/lib64/python3.12/site-packages/sqlalchemy/engine/row.py� __setattr__zRow.__setattr__P s � � � 2�3�3� c � � t d� �)Nzcan't delete attributer$ )r& r' s r) � __delattr__zRow.__delattr__S s � � � 5�6�6r+ c � � | S )a5 Return a 'tuple' form of this :class:`.Row`.

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. r" c � � y r> r" rR s r) r] zRowMapping.__getitem__f s � �Sr+ c �, � t | j � S r> )r� r; r/ s r) � _values_implzRowMapping._values_implk s � ��D�J�J� � r+ c �< � d� | j j D � S )Nc 3 �& K � | ] }|��|�� � y �wr> r" )�.0r| s r) � <genexpr>z&RowMapping.__iter__.<locals>.<genexpr>o s � �� �>�,�a�� ��,�s ���r9 r{ r/ s r) r� zRowMapping.__iter__n s � �>�4�<�<�,�,�>�>r+ c �, � t | j � S r> )r� r; r/ s r) r� zRowMapping.__len__q s � ��4�:�:�� r+ c �8 � | j j |� S r> )r9 rJ rR s r) rT zRowMapping.__contains__t s � ��|�|�$�$�S�)�)r+ c �* � t t | � � S r> )rv r r/ s r) ry zRowMapping.__repr__w s � ��D��J� � r+ c �f � t | | j � D �cg c] }|| | f�� c}� S c c}w )zeReturn a view of key/value tuples for the elements in the underlying :class:`.Row`. )r� r{ rR s r) r� zRowMapping.itemsz s7 � � "� �t�y�y�{�;�{��C��c��#�{�;� � ��;s �. c �. � | j j S )znReturn a view of 'keys' for string column names represented by the underlying :class:`.Row`. r� r/ s r) r{ zRowMapping.keys� s � � �|�|� � � r+ c �6 � t | | j � � S )zeReturn a view of values for the values represented in the underlying :class:`.Row`. )r� r� r/ s r) �valueszRowMapping.values� s � � '�t�T�->�->�-@�A�Ar+ N)rS r rI r )rI z List[Any])rI z Iterator[str]r� )rS �objectrI r� r� )rI r� )rI r )rI r� )r� r� r� r� r� r r] r �_get_by_key_impl_mappingr� r� r� rT ry r� r{ r� r" r+ r) r8 r8 H sJ � ��2 �I��8� �6�6� � �?� �*� � �!�Br+ r8 )1r� � __future__r �abcr �collections.abcrE ra �typingr r r r r r r r r r r r r r r �sqlr rw r � util._has_cyr �_py_rowr �"sqlalchemy.cyextension.resultproxy�resultr r r r r r! � BaseRowProxy�RowProxyr� �KeysView� ValuesViewr� � ItemsViewr� r8 r" r+ r) �<module>r� s �� 5� "� � )� � � � � � � � � � � � � � � � � � "� � *���+�E�� �'�!� �T�� �� �e�5��c��?�+��f#�'�8�C�=�'�#�,� f#�R � � �� )�C� )�> ��6�?�?�:�.��0A�0A�#�0F� � � ��(8�(8��S� �(I� �HB��&�.�.��S� �9� HBr+
