    .. container:: inherited_member

        The :func:`sqlalchemy.dialects.mysql.insert` function creates
        a :class:`sqlalchemy.dialects.mysql.Insert`.  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.

    The :class:`_mysql.Insert` construct includes additional methods
    :meth:`_mysql.Insert.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.

        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:`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.
