The following example writes a JSON object with the a1, a2, a3, and a4 attributes. a3 is an SDO_GEOMETRY, encoded as GeoJSON.

DECLARE
  l_sdo_geometry mdsys.sdo_geometry := sdo_geometry( 2001, 4326, sdo_point_type( 10, 50, null ), null, null );
BEGIN
  apex_json.open_object; -- {
  apex_json.write('a1', 1); -- "a1": 1
  apex_json.write('a2', 'two'); -- ,"a2": "two"
  apex_json.write('a3', l_sdo_geometry); -- ,"a3": { "type": "Point", "coordinates": [ 10, 50 ] }
  apex_json.write('a4', false); -- ,"a4": false
  apex_json.close_object; -- }
END;
