Can mdsys.sdo_relate return FALSE?

Question

I have the following query:
SELECT MIN (dtczas) dtczas
FROM sd_car_location
WHERE dyza_id = 2
AND dtczas > '24-JUN-2002 11:06:48'
AND mdsys.sdo_relate(
geom,
MDSYS.SDO_GEOMETRY( 2003, NULL, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3),
MDSYS.SDO_ORDINATE_ARRAY( 3734329.56686484, 5567865.09443332,
3735261.90177227, 5568277.30732063 )
'mask=ANYINTERACT querytype=WINDOW') = 'FALSE'
while executing this query I receive:
ORA-29902: error in executing ODCIIndexStart() routine
ORA-13207: incorrect use of the [SDO_RELATE] operator
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 84
ORA-06512: at line 1
so, is it possible to use sdo_relate in such way? When I try "<> 'TRUE'" or "AND NOT .... = 'TRUE'" index is not used.
Thanks in advance for help.

Answer 1

It is not possible. You must use ='TRUE'.
The reason for this is related to how the operators work.
First they do an index lookup to return the data that is
likely to interact, then they do further filtering to find the
data that actually interacts. All operators use the index
in this way.
If ='FALSE' was allowed, you'd get an answer that includes
only the geometries that were likely to interact (returned from
the index query), but that didn't interact, i.e. wrong answer.
You might be able to do something like this:
select min (dtczas) from
SELECT dtczas
FROM sd_car_location
WHERE dyza_id = 2
AND dtczas > '24-JUN-2002 11:06:48
MINUS
SELECT dtczas
FROM sd_car_location
WHERE dyza_id = 2
AND dtczas > '24-JUN-2002 11:06:48'
AND mdsys.sdo_relate(
geom,
MDSYS.SDO_GEOMETRY( 2003, NULL, NULL, MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 3),
MDSYS.SDO_ORDINATE_ARRAY( 3734329.56686484, 5567865.09443332,
3735261.90177227, 5568277.30732063 ) ),
'mask=ANYINTERACT querytype=WINDOW') = 'TRUE');
Hope this helps,
