This class is based on the dialect-agnostic :class:`_sql.Insert` construct which may be constructed using the :func:`_sql.insert` function in SQLAlchemy Core.

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 mysqlFr6ReadOnlyColumnCollection[str, KeyedColumnElement[Any]]c|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.insertedDs@"**rrc.t|jdS)Nr')name)rrr%s rr#zInsert.inserted_aliasfsTZj1111r_post_values_clausezDThis Insert construct already has an ON DUPLICATE KEY clause present)msgsargs _UpdateArgkwrrc|r|rtjd|r0t|dkrtjd|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 ArgumentErrorlenOnDuplicateClauser#r*)r&r,r.valuess ron_duplicate_key_updatezInsert.on_duplicate_key_updatejsh  B #K   4yy1}}'0!WFFF#4  $ $   rN)rr!)rr)r,r-r.rrr)__name__ __module__ __qualname____doc__stringify_dialect inherit_cachepropertyr'r memoized_propertyr#rrr5rrrr5s   M +++X+B 2222 !$5 >>>[>>>rc.eZdZUdZdZded<dZd d ZdS)r3r5NzOptional[List[str]]_parameter_orderingr r#rupdater-rNonec|||_t|tr=|r;t|dtr d|D|_t |}t|t r|st dn4t|trt |}nt d||_dS)Nrcg|]\}}|Sr>r>).0keyvalues r z.OnDuplicateClause.__init__..s'E'E'E U'E'E'Erz-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#rAs r__init__zOnDuplicateClause.__init__s- fd # # "  "!&)U33 "(F'Ef'E'E'ED $&\\F fd # #   C  0 1 1 &\\FF$   r)r#rrAr-rrB)r6r7r8__visit_name__r@__annotations__r:rNr>rrr3r3sG.N/33333rr3N)rr rr)$ __future__rtypingrrrrrr r r sql._typingr sql.baserrrrsql.dmlrStandardInsert sql.elementsrrsql.expressionrsql.selectabler util.typingr__all__rr3strr-r>rrr^s"#""""",,,,,,******######((((((000000//////))))))......######------ &{{{{{^{{{|##### ###L CHtE#s(O,.>sCx.HH r
