This example collects statistics on a non-indexed geospatial column.

You define the following table.

     CREATE TABLE stat_t2 (
       rownum INTEGER, 
       a      INTEGER, 
       b      INTEGER, 
       c      INTEGER, 
       d      INTEGER, 
       e      INTEGER, 
       sp     ST_GEOMETRY, 
       dummy  CHARACTER(20000));

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

     COLLECT STATISTICS COLUMN(sp) ON stat_t2;
