Shorten my spatial query statement

Question

HI ,
Can anybody help me shorten this query statement?
Thanks!
select tile.filename,
SDO_GEOM.SDO_AREA(
SDO_GEOM.SDO_INTERSECTION(tile.geometry,
MDSYS.SDO_GEOMETRY(2003, 8307, NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 1),
MDSYS.SDO_ORDINATE_ARRAY(50,10, 70,10, 70,50, 50,50, 50,10)),
0.0005),0.0005) as area
from tile
WHERE tile.archiveId = 1
AND tile.dataType = 'Ortho'
AND
SDO_GEOM.SDO_AREA(
SDO_GEOM.SDO_INTERSECTION(tile.geometry,
MDSYS.SDO_GEOMETRY(2003, 8307, NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 1),
MDSYS.SDO_ORDINATE_ARRAY(50,10, 70,10, 70,50, 50,50, 50,10)),
0.0005),0.0005) > 0
ORDER BY tileid;

You can define your test geometry once in an inline view, and use sdo_relates (ie, anyinteract and not touch) to ensure area>0. Something like this...
select a.filename, a.tileid
SDO_GEOM.SDO_AREA(
SDO_GEOM.SDO_INTERSECTION(a.geometry, b.g,0.0005),0.0005) as area
from tile a,
(select MDSYS.SDO_GEOMETRY(2003, 8307, NULL,
MDSYS.SDO_ELEM_INFO_ARRAY(1, 1003, 1),
MDSYS.SDO_ORDINATE_ARRAY(50,10, 70,10, 70,50, 50,50, 50,10)) as g
from dual) b
where a.archiveid=1
and a.dataType = 'Ortho'
and sdo_anyinteract(a.geometry, b.g) = 'TRUE'
and sdo_touch(a.geometry, b.g) != 'TRUE'
order by a.tileid
I won't say it's necessarily optimized, but it's a little shorter.
