    construct.

    .. container:: inherited_member

        The :func:`sqlalchemy.dialects.sqlite.insert` function creates
        a :class:`sqlalchemy.dialects.sqlite.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:`_sqlite.Insert` construct includes additional methods
    :meth:`_sqlite.Insert.on_conflict_do_update`,
    :meth:`_sqlite.Insert.on_conflict_do_nothing`.

        SQLite's ON CONFLICT clause allows reference to the row that would
        be inserted, known as ``excluded``.  This attribute provides
        all columns in this row to be referenceable.

        .. tip::  The :attr:`_sqlite.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"]``.  See the docstring for
            :class:`_expression.ColumnCollection` for further examples.

         A sequence consisting of string column names, :class:`_schema.Column`

        :param index_where:
         Additional WHERE criterion that can be used to infer a

         A dictionary or other mapping object

         matching that of the target table, and expressions or literals
         as values, specifying the ``SET`` actions to take.

            :paramref:`_sqlite.Insert.on_conflict_do_update.set_`
            parameter supports :class:`_schema.Column` objects from the target
            :class:`_schema.Table` as keys.

            Python-specified default UPDATE values or generation functions,

            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).
