SEM_APIS.CONVERT_TO_GML311_LITERAL(
     geom         IN SDO_GEOMETRY, 
     options      IN VARCHAR2 default NULL
     )RETURN CLOB;

Description

Serializes an SDO_GEOMETRY object into an ogc:gmlLiteral value.

Parameters

geom

SDO_GEOMETRY object to be serialized.

options

(Reserved for future use.)

Usage Notes

The procedure SDO_UTIL.TO_GML311GEOMETRY is used internally to create the geometry literal with a certain spatial reference system URI.

For more information about geometry serialization, see SDO_UTIL.TO_GML311GEOMETRY.

Examples

The following example shows the use of this function for a geometry with SRID 8307 The COLA_MARKETS table is the one from the simple example in Oracle Spatial Developer's Guide.

INSERT INTO cola_markets VALUES(
  10,
  'cola_x',
  SDO_GEOMETRY(
    2003,
    8307, -- SRID
    NULL,
    SDO_ELEM_INFO_ARRAY(1,1003,3),
    SDO_ORDINATE_ARRAY(1,1, 6,13)
  )
);
commit;

SELECT
sem_apis.convert_to_gml311_literal(shape) as gml1
FROM cola_markets;
