        """ExecuteSQL(self, statement, spatialFilter: ogr.Geometry = None, dialect: Optional[str] = "", keep_ref_on_ds=False) -> ogr.Layer

        The result of a SQL query is:
          - None (or an exception if exceptions are enabled) for statements
            that are in error
          - or None for statements that have no results set,

        Note that this ogr.Layer is in addition to the layers in the data store
        and must be released with ReleaseResultSet() before the data source is closed
        (destroyed).

        Starting with GDAL 3.7, this method can also be used as a context manager,
        as a convenient way of automatically releasing the returned result layer.

        review the OGR SQL document (:ref:`ogr_sql_sqlite_dialect`)

        ----------

        dialect:
            allows control of the statement dialect. If set to None or empty string,
            the OGR SQL engine will be used, except for RDBMS drivers that will
            use their dedicated SQL engine, unless OGRSQL is explicitly passed as
            the dialect. The SQLITE dialect can also be used.
        keep_ref_on_ds:
            whether the returned layer should keep a (strong) reference on

        -------

        OGR_F_GetNativeData(OGRFeatureH hFeat)

        Returns the native data for the feature.

        The native data is the representation in a "natural" form that comes

        output driver. The native data may be in different format, which is

        Note that most drivers do not support storing the native data in the
        feature object, and if they do, generally the NATIVE_DATA open option
        must be passed at dataset opening.

        The "native data" does not imply it is something more performant or
        powerful than what can be obtained with the rest of the API, but it
        may be useful in round-tripping scenarios where some characteristics
        of the underlying format are not captured otherwise by the OGR

        Set default field value.

        The default field value is taken into account by drivers (generally
        those with a SQL interface) that support it at field creation time.
        OGR will generally not automatically set the default field value to
        null fields by itself when calling OGRFeature::CreateFeature() /
        OGRFeature::SetFeature(), but will let the low-level layers to do the
        job. So retrieving the feature from the layer is recommended.

        The accepted values are NULL, a numeric value, a literal value
        enclosed between single quote characters (and inner single quote
        characters escaped by repetition of the single quote character),
        CURRENT_TIMESTAMP, CURRENT_TIME, CURRENT_DATE or a driver specific
        expression (that might be ignored by other drivers). For a datetime
        literal value, format should be 'YYYY/MM/DD HH:MM:SS[.sss]'
        (considered as UTC time).

        Drivers that support writing DEFAULT clauses will advertise the
        GDAL_DCAP_DEFAULT_FIELDS driver metadata item.

        This function is the same as the C++ method
        OGRFieldDefn::SetDefault().
