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. .. tip:: The :attr:`_mysql.Insert.inserted` attribute is an instance of :class:`_expression.ColumnCollection`, which provides an interface the same as that of the :attr:`_schema.Table.c` collection described at :ref:`metadata_tables_and_columns`. With this collection, ordinary names are accessible like attributes (e.g. ``stmt.inserted.some_column``), but special names and dictionary method names should be accessed using indexed access, such as ``stmt.inserted["column name"]`` or ``stmt.inserted["values"]``. See the docstring for :class:`_expression.ColumnCollection` for further examples. .. seealso:: :ref:`mysql_insert_on_duplicate_key_update` - example of how to use :attr:`_expression.Insert.inserted` )inserted_aliascolumnsselfrrrinsertedDs zInsert.insertedrcCst|jddS)Nr#)name)rrr!rrrrfszInsert.inserted_alias_post_values_clausezDThis Insert construct already has an ON DUPLICATE KEY clause present)msgsargs _UpdateArgkwrrcOsL|r |r td|rt|dkrtd|d}n|}t|j||_|S)aO Specifies the ON DUPLICATE KEY UPDATE clause. :param \**kw: Column keys linked to UPDATE values.

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:`tutorial_parameter_ordered_updates`:: 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 simultaneouslyzDOnly a single dictionary or list of tuples is accepted positionally.r)r ArgumentErrorlenOnDuplicateClauserr%)r"r'r)valuesrrron_duplicate_key_updatejs4  zInsert.on_duplicate_key_updateN)rr)rr)r'r(r)rrr)__name__ __module__ __qualname____doc__stringify_dialect inherit_cachepropertyr#r memoized_propertyrrr r/rrrrr5s  ! c@s,eZdZUdZdZded<dZdd d ZdS)r-r/NzOptional[List[str]]_parameter_orderingrrrupdater(rNonecCsx||_t|tr|rt|dtrdd|D|_t|}t|tr)|s(tdnt|tr3t|}ntd||_dS)NrcSsg|]\}}|qSrr).0keyvaluerrr sz.OnDuplicateClause.__init__..z-update parameter dictionary must not be emptyztupdate parameter must be a non-empty dictionary or a ColumnCollection such as the `.c.` collection of a Table object) r isinstancelisttupler8dict ValueErrorrr9)r"rr9rrr__init__s(      zOnDuplicateClause.__init__)rrr9r(rr:)r0r1r2__visit_name__r8__annotations__r4rDrrrrr-s  r-N)rr rr)$ __future__rtypingrrrrrrr r sql._typingr sql.baser rrrsql.dmlrStandardInsert sql.elementsrrsql.expressionrsql.selectabler util.typingr__all__rr-strr(rrrrs6                     ~&$
