This example collects statistics on the geospatial index defined on geospatial column sp.

You define the following table.

     CREATE TABLE stat_t2_idx (
       rownum INTEGER, 
       a      INTEGER, 
       b      INTEGER, 
       c      INTEGER, 
       d      INTEGER, 
       e      INTEGER, 
       sp     ST_GEOMETRY, 
       dummy  CHARACTER(20000))
     INDEX (sp);

You can then collect statistics on the geospatial index sp, using a request like the following.

     COLLECT STATISTICS INDEX(sp) ON stat_t2_idx;
