Error in spatial index

Question

Hi, everyone
I created a spatial index on a table, but i get the error message:
ORA-13033: the data in sdo_elem_info_array of sdo_geometry is unavailable
How can i write a SQL command to delete those unavailable records?

Hi,
here you find an example with a similar error. You simply can validate the spatial data, to find invalid records:
DROP   TABLE sdo_test;
CREATE TABLE sdo_test (
  nr      NUMBER,
  GEOM     MDSYS.SDO_GEOMETRY);
COMMIT;
--correct
INSERT INTO sdo_test VALUES (1,
  SDO_GEOMETRY(3302, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
    SDO_ORDINATE_ARRAY(-87.899771, 42.000853, 0, -87.899109, 42.000847, 54.8504622)));
--correct
INSERT INTO sdo_test VALUES (2,
  SDO_GEOMETRY(3302, 8307, NULL, SDO_ELEM_INFO_ARRAY(1, 2, 1),
    SDO_ORDINATE_ARRAY(-87.917489, 41.992077, 0, -87.917063, 41.99174, 51.4503307)));
--empty SDO_ELEM_INFO_ARRAY
INSERT INTO sdo_test VALUES (3,
  SDO_GEOMETRY(3302, 8307, NULL,  SDO_ELEM_INFO_ARRAY(),
    SDO_ORDINATE_ARRAY(-87.925704, 41.965994, 0, -87.925705, 41.965445, 60.9789892)));
DELETE FROM USER_SDO_GEOM_METADATA
  WHERE TABLE_NAME = 'SDO_TEST' AND COLUMN_NAME = 'GEOM' ;
INSERT INTO USER_SDO_GEOM_METADATA (TABLE_NAME, COLUMN_NAME, DIMINFO, SRID)
  VALUES ('SDO_TEST', 'GEOM',
    MDSYS.SDO_DIM_ARRAY
      (MDSYS.SDO_DIM_ELEMENT('X', -87.925705, -87.8991090, 0.001),
       MDSYS.SDO_DIM_ELEMENT('Y',  41.965445,  41.9654450, 0.001),
       MDSYS.SDO_DIM_ELEMENT('M',    0.00000,  60.9789892, 0.001)
     ),8307);
--DROP   INDEX sdo_test_geom_spix;
--ORA ERROR 13033
CREATE INDEX sdo_test_geom_spix
          ON sdo_test(geom)
   INDEXTYPE IS MDSYS.SPATIAL_INDEX

--find the invalid record
SELECT nr, SDO_GEOM.VALIDATE_GEOMETRY(geom,0.001) val
  FROM sdo_test;

1    TRUE
2    TRUE
3    13033
