Impossible to create an index with an object table

Question

Is it possible to use object tables with Oracle Spatial ?
With Oracle 8.1.7.0.0, here is the example where I encounter a problem (this example works of course with an equivalent relational table) :
create or replace type zonegeo as object (
id integer, definitionGeo MDSYS.SDO_GEOMETRY
create table essaigeo of zonegeo (id PRIMARY KEY)
OBJECT ID PRIMARY KEY;
INSERT INTO USER_SDO_GEOM_METADATA
VALUES ('ESSAIGEO','DEFINITIONGEO',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('X', 47680.000, 1197822.000, 0.005),
MDSYS.SDO_DIM_ELEMENT('Y', 1620431.000, 2677441.000, 0.005)
NULL -- SRID
CREATE INDEX ESSAIGEO_SPATIAL_IDX
ON ESSAIGEO(DEFINITIONGEO)
INDEXTYPE IS MDSYS.SPATIAL_INDEX
PARAMETERS ('SDO_LEVEL = 6);
ERREUR ` la ligne 1 :
ORA-29855: erreur d'exicution de la routine ODCIINDEXCREATE

Answer 1

In Oracle 8.1.7 you cannot embed a geometry type in another type and index it.
In 9i, you can , but not in the way you've defined it, i.e. you have to create a regular
table, and have a column of type zonegeo, and make a few other changes, i.e.:
create or replace type zonegeo as object (
id integer, definitionGeo MDSYS.SDO_GEOMETRY
create table essaigeo (zone zonegeo);
INSERT INTO USER_SDO_GEOM_METADATA
VALUES ('ESSAIGEO','ZONE.DEFINITIONGEO',
MDSYS.SDO_DIM_ARRAY(
MDSYS.SDO_DIM_ELEMENT('X', 47680.000, 1197822.000, 0.005),
MDSYS.SDO_DIM_ELEMENT('Y', 1620431.000, 2677441.000, 0.005)
NULL -- SRID
CREATE INDEX ESSAIGEO_SPATIAL_IDX
ON ESSAIGEO(ZONE.DEFINITIONGEO)
INDEXTYPE IS MDSYS.SPATIAL_INDEX
PARAMETERS ('SDO_LEVEL = 6);
