SDO_RELATE does not return expected points

Question

Hi,
I have a problem with a query which does not return the results I am expecting. I think it may be to do with geodetic data v projected data but fail to see how.
the table points2 contains point data stored in Lat Long (SRID 8307)
Here is my query:
SELECT mdsys.sdo_cs.transform(points2.assetextent,26943) FROM points2
WHERE SDO_RELATE (points2.ASSETEXTENT, MDSYS.SDO_GEOMETRY(2003,26943 ,NULL, mdsys.SDO_ELEM_INFO_ARRAY(1,1003,3), mdsys.SDO_ORDINATE_ARRAY(1831679.1743184,644380.053168771,1831699.1743184,645000.053168677)),'mask=anyinteract') = 'TRUE';
This query returns 0 results. if perform the same query with SDO_FILTER rather than SDO_RELATE then I get 1 result (which is what I expect). the result is this:
MDSYS.SDO_CS.TRANSFORM(POINTS2.ASSETEXTENT,26943)(SDO_GTYPE, SDO_SRID, SDO_POINT(X, Y, Z), SDO_ELEM_INFO, SDO_ORDINATES)
SDO_GEOMETRY(3001, 26943, NULL, SDO_ELEM_INFO_ARRAY(1, 1, 1), SDO_ORDINATE_ARRAY(1831689.17, 644440.053, 0))
1 row selected.
As can clearly be seen from this result the point is 10m from the both vertical edges of the optimised rectangle and at least 60m from the horizontal edges.
The sdo_geom_metadata_table entry for this table is:
SDO_OWNER SDO_TABLE_NAME
SDO_COLUMN_NAME
SDO_DIMINFO(SDO_DIMNAME, SDO_LB, SDO_UB, SDO_TOLERANCE)
SDO_SRID
VST POINTS2
ASSETEXTENT
SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -180, 180, .005), SDO_DIM_ELEMENT('Y', -90, 90, .005), SDO_DIM_ELEMENT('Z', -999, 5000, .005))
8307
Anyone got any pointers? If you need more info just let me know

hi,
can you try this query and let us know what you get ?
Transform the geometry to 8307 and pass it into the sdo_relate
operator.
SELECT mdsys.sdo_cs.transform(points2.assetextent,26943) FROM points2
WHERE SDO_RELATE (points2.ASSETEXTENT,
sdo_cs.transform(MDSYS.SDO_GEOMETRY(2003,26943 ,NULL, mdsys.SDO_ELEM_INFO_ARRAY(1,1003,3), mdsys.SDO_ORDINATE_ARRAY(1831679.1743184,644380.053168771,
1831699.1743184,645000.053168677)), 8307), 'mask=anyinteract') = 'TRUE';
