Adds methods for MySQL-specific syntaxes such as ON DUPLICATE KEY UPDATE. The :class:`~.mysql.Insert` object is created using the :func:`sqlalchemy.dialects.mysql.insert` function. .. versionadded:: 1.2 c � � | j j S )a� Provide the "inserted" namespace for an ON DUPLICATE KEY UPDATE statement MySQL's ON DUPLICATE KEY UPDATE clause allows reference to the row that would be inserted, via a special function called ``VALUES()``. This attribute provides all columns in this row to be referenceable such that they will render within a ``VALUES()`` function inside the ON DUPLICATE KEY UPDATE clause. The attribute is named ``.inserted`` so as not to conflict with the existing :meth:`_expression.Insert.values` method. .. seealso:: :ref:`mysql_insert_on_duplicate_key_update` - example of how to use :attr:`_expression.Insert.inserted` )�inserted_alias�columns��selfs �q/builddir/build/BUILD/cloudlinux-venv-1.0.10/venv/lib64/python3.11/site-packages/sqlalchemy/dialects/mysql/dml.py�insertedzInsert.inserted s � �$ �"�*�*� c �. � t | j d�� � S )Nr )�name)r �tabler s r r zInsert.inserted_alias- s � ��T�Z�j�1�1�1�1r c �� � |r|rt j d� � �|r0t |� � dk rt j d� � �|d }n|}t | dd� � }t ||� � | _ | S )aE Specifies the ON DUPLICATE KEY UPDATE clause. :param \**kw: Column keys linked to UPDATE values. The values may be any SQL expression or supported literal Python values. .. warning:: This dictionary does **not** take into account Python-specified default UPDATE values or generation functions, e.g. those specified using :paramref:`_schema.Column.onupdate`. These values will not be exercised for an ON DUPLICATE KEY UPDATE style of UPDATE, unless values are manually specified here. :param \*args: As an alternative to passing key/value parameters, a dictionary or list of 2-tuples can be passed as a single positional argument. Passing a single dictionary is equivalent to the keyword argument form:: insert().on_duplicate_key_update({"name": "some name"}) Passing a list of 2-tuples indicates that the parameter assignments in the UPDATE clause should be ordered as sent, in a manner similar to that described for the :class:`_expression.Update` construct overall in :ref:`updates_order_parameters`:: insert().on_duplicate_key_update( [("name", "some name"), ("value", "some value")]) .. versionchanged:: 1.3 parameters can be specified as a dictionary or list of 2-tuples; the latter form provides for parameter ordering. .. versionadded:: 1.2 .. seealso:: :ref:`mysql_insert_on_duplicate_key_update` z9Can't pass kwargs and positional arguments simultaneously� zDOnly a single dictionary or list of tuples is accepted positionally.� r N)r � ArgumentError�len�getattr�OnDuplicateClause�_post_values_clause)r �args�kw�valuesr s r �on_duplicate_key_updatez Insert.on_duplicate_key_update1 s� � �Z � �B� ��#�K�� � � � ��4�y�y�1�}�}��'�0�� � � �!�W�F�F��F� ��'7��>�>��#4�^�V�#L�#L�� �� r N) �__name__� __module__� __qualname__�__doc__�propertyr r �memoized_propertyr r r" � r r r r ss � � � � � � � � �+� +� �X�+�& ��2� 2� ��2� �=� =� �[�=� =� =r r z.dialects.mysql.insertz.dialects.mysql.Insertc � � e Zd ZdZdZd� ZdS )r r" Nc � � || _ t |t � � r=|r;t |d t � � r d� |D � � | _ t |� � }|rt |t � � st d� � �|| _ d S )Nr c � � g | ]\ }}|��S r) r) )�.0�key�values r � <listcomp>z.OnDuplicateClause.__init__.<locals>.<listcomp>� s � �'E�'E�'E� ��U��'E�'E�'Er z/update parameter must be a non-empty dictionary)r � isinstance�list�tuple�_parameter_ordering�dict� ValueError�update)r r r7 s r �__init__zOnDuplicateClause.__init__| s� � � ,��� �f�d� #� #� "� � "�!�&��)�U�3�3� "� (F�'E�f�'E�'E�'E�D� $��&�\�\�F�� P�Z��� 5� 5� P� � N�O�O� O� �� � � r )r# r$ r% �__visit_name__r4 r8 r) r r r r w s. � � � � � �.�N� �� � � � � r r N)� r r �sql.baser �sql.dmlr �StandardInsert� sql.elementsr �sql.expressionr �util.langhelpersr �__all__r r r) r r �<module>rB s �� � � � � � � � � � � � � #� #� #� #� #� #� /� /� /� /� /� /� )� )� )� )� )� )� #� #� #� #� #� #� .� .� .� .� .� .� ��b� b� b� b� b�^� b� b� b�J � � � $�&>� � �� � � � � � � � � � � r
