This attribute provides all columns in this row to be referenceable. .. tip:: The :attr:`_postgresql.Insert.excluded` 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.excluded.some_column``), but special names and dictionary method names should be accessed using indexed access, such as ``stmt.excluded["column name"]`` or ``stmt.excluded["values"]``.

These values will not be exercised for an ON CONFLICT style of UPDATE, unless they are manually specified in the :paramref:`.Insert.on_conflict_do_update.set_` dictionary. :param where: Optional argument. If present, can be a literal SQL string or an acceptable expression for a ``WHERE`` clause that restricts the rows affected by ``DO UPDATE SET``. Rows not meeting the ``WHERE`` condition will not be updated (effectively a ``DO NOTHING`` for those rows). .. seealso:: :ref:`postgresql_insert_on_conflict` )OnConflictDoUpdater*)r) constraintindex_elements index_whereset_wheres r!on_conflict_do_updatezInsert.on_conflict_do_updateks$z$6  T5$   r"c*t||||_|S)a  Specifies a DO NOTHING action for ON CONFLICT clause.
