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;
