Can't Query Saptial Data

Question

Hi, I've smoothly created a R-Tree spatial index on a Index Organized Table(IOT) named ch100_polygon_iot( about 120 thousand rows ) containing only polygon geometries. But when I run the spatial query statements, I get the following error messages:
declare
i int;
j int;
RecNum int;
GIDNUM number;
NUM INT;
dis number(10,0);
time1 date;
time2 date;
DisStr varchar2(30);
GEOID VARCHAR2(40);
GEO mdsys.sdo_geometry;
begin
dis:=power(10,i);
DisStr:='distance = '|| to_char(dis);
time1:=sysdate;
NUM:=0;
for j in 0..10 loop
GIDNUM:=(j*12200);
SELECT GEOMETRY INTO GEO FROM scott.CH100_POLYGON_iot WHERE oID=GIDNUM;
SELECT count(*) INTO RecNum FROM scott.CH100_POLYGON_realiot A
WHERE SDO_RELATE(A.Geometry,GEO,'mask=ANYINTERACT querytype=WINDOW') = 'TRUE';
NUM:=NUM+RecNum;
end loop;
time2:=sysdate;
/*insert into zyz.TEST_RESULT_TABLE (TEST_DESC,TIME_ELIPE,TEST_TIME)

Sorry - Oracle knew that. I had no idea.
Section 2.4.1 in the doc -
2.4.1 TABLE_NAME
The TABLE_NAME column contains the name of a feature table, such as COLA_MARKETS, that has a column of type SDO_GEOMETRY.
The table name is stored in the spatial metadata views in all uppercase characters.
The table name cannot contain spaces or mixed-case letters in a quoted string when inserted into the USER_SDO_GEOM_METADATA view, and it cannot be
in a quoted string when used in a query (unless it is in all uppercase characters).
The spatial feature table cannot be an index-organized table if you plan to create a spatial index on the spatial column.
