Adds methods for SQLite-specific syntaxes such as ON CONFLICT. The :class:`_sqlite.Insert` object is created using the :func:`sqlalchemy.dialects.sqlite.insert` function. .. versionadded:: 1.4 .. seealso:: :ref:`sqlite_on_conflict_insert` sqliteFcDt|jdjS)aProvide the ``excluded`` namespace for an ON CONFLICT statement 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"]``.
