The :class:`~.mysql.Insert` object is created using the :func:`sqlalchemy.dialects.mysql.insert` function. .. versionadded:: 1.2 mysqlFc.|jjS)aProvide 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. .. 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_aliascolumnsselfs rinsertedzInsert.insertedEs@""***rc0t|jdS)Nr&)name)rrr$s rr"zInsert.inserted_aliasgsTZZj11r_post_values_clausezDThis Insert construct already has an ON DUPLICATE KEY clause present)msgsc|r|rtjd|r)t|dkDrtjd|d}n|}t|j||_|S)a 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 ArgumentErrorlenOnDuplicateClauser"r))r%argskwvaluess ron_duplicate_key_updatezInsert.on_duplicate_key_updatekswp B##K  4y1}''0!WFF#4   $   rN)returnz6ReadOnlyColumnCollection[str, KeyedColumnElement[Any]])r4r)r0 _UpdateArgr1rr4r)__name__ __module__ __qualname____doc__stringify_dialect inherit_cachepropertyr&r memoized_propertyr"rrr3rrrr6s|  M + ?++B 22 !$5 BBrcBeZdZUdZdZded<ded<dZ d dZy) r/r3NzOptional[List[str]]_parameter_orderingzDict[str, Any]updater cV||_t|tr:|r8t|dtr%|Dcgc]\}}| c}}|_t |}t|t r |s9t dt|trt |}||_yt d||_ycc}}w)Nrz-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" isinstancelisttupler@dict ValueErrorrrA)r%r"rAkeyvalues r__init__zOnDuplicateClause.__init__s- fd # z&)U3>D'E U'ED $&\F fd # C 0 1&\F $   !(Fs B%)r"rrAr5r4None)r6r7r8__visit_name__r@__annotations__r:rJr>rrr/r/s<.N/3,3 -7A rr/N)rrr4r)% __future__rtypingrrrrrr r r r sql._typingrsql.baserrrrsql.dmlrStandardInsert sql.elementsrrsql.expressionrsql.selectabler util.typingr__all__rr/strr5r>rrr[s#,*#(0/).#- &^D$ $N CHtE#s(O,.>sCx.HH r
