    This method can be used to force the dataset to close when one more references to the dataset are still reachable. If `Close()` is never called, the dataset will be closed automatically during garbage collection.

    In most cases, it is preferable to open or create a dataset using a context manager instead of calling `Close()` directly.

    Parameters:

      - name (string) -- the name for the new layer. This should ideally not match any existing layer on the datasource.

      - geom_type (int, default = `ogr.wkbUnknown`) -- geometry type for the layer. Use `ogr.wkbUnknown` if there are no constraints on the types geometry to be written.

      - options (dict/list, optional) -- Driver-specific dict or list of name=value options

    Return type:

      ogr.Layer or `None` on failure.

    Examples

        >>> ds.GetLayerCount()
        0

      value (int/str) -- Name or 0-based index of the layer to delete.

  EndAsyncReader(Dataset self, AsyncReader ario)
  ExecuteSQL(self, statement, spatialFilter: ogr.Geometry = None, dialect: str | None = '', keep_ref_on_ds=False) → ogr.Layer

    Execute a SQL statement against the dataset

    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,

      - or a `ogr.Layer` handle representing a results set from the query.

    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.

    For more information on the SQL dialect supported internally by OGR review the OGR SQL document (OGR SQL dialect and SQLITE SQL dialect) Some drivers (i.e. Oracle and PostGIS) pass the SQL directly through to the underlying RDBMS.

    The SQLITE dialect can also be used (SQL SQLite dialect)

    Parameters:

      - statement -- the SQL statement to execute (e.g "SELECT * FROM layer")

      - spatialFilter -- a geometry which represents a spatial filter. Can be None

      - 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 the current dataset. Cf example 2 for a use case.

    Returns:

      a ogr.Layer containing the results of the query, that will be automatically released when the context manager goes out of scope.

    Return type:

      ogr.Layer

    Examples

    1. Use as a context manager:

        >>> with ds.ExecuteSQL("SELECT * FROM layer") as lyr:
        ...     print(lyr.GetFeatureCount())

    2. Use keep_ref_on_ds=True to return an object that keeps a reference to its dataset:

        >>> def get_sql_lyr():
        ...     return gdal.OpenEx("test.shp").ExecuteSQL("SELECT * FROM test", keep_ref_on_ds=True)
        ...
