Problem with loading sdo_geometry with sql loader

Question

Hi All,
I i'm trying to load some geometries, and i'm using sql loader for that.
example entry of my data file looks like this:
1,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
Geometry is stored in wkb format. To be able to add SRID information to geometry i created the function in database which looks like this:
create or replace function sdo_geom_form_wkb_text(wkb_text IN VARCHAR2) RETURN
sdo_geometry as
SRID_VALUE NUMBER := 8307;
BEGIN
return sdo_geometry(to_blob(HEXTORAW(wkb_text)), SRID_VALUE);
end sdo_geom_form_wkb_text;
and i would like to invoke this method during load. To do this i look in some forums where there were examples with using from_wkt function and i made my own ctl file:
OPTIONS (SKIP=0,BINDSIZE=20000000,ROWS=10000,ERRORS=500,DIRECT=true)
LOAD DATA
INFILE 'c:\geometry\face2.dat'
BADFILE 'c:\geometry\face2.bad'
TRUNCATE
CONTINUEIF NEXT(1:1) = '#'
INTO TABLE TEST_TABLE
FIELDS TERMINATED BY ','
TRAILING NULLCOLS (
ID INTEGER EXTERNAL,
string_geom BOUNDFILLER,
GEOMETRY EXPRESSION "sdo_geom_form_wkb_text(:string_geom)"
when i invoke sqlloader i'm getting:
SQL*Loader-951: Error calling once/load initialization
ORA-26052: Unsupported type 121 for SQL expression on column GEOMETRY.
Could anyone tell what i'm doing wrong?
Thanks,

864742,
. . . .Forget the function and use the SDO_GEOMETRY constructor.
-- "NOTE: here I'm assuming your SRID is 8307"
ID          INTEGER EXTERNAL,
string_geom BOUNDFILLER,
GEOMETRY    EXPRESSION "SDO_GEOMETRY(:string_geom, 8307)"
.... . . .Credit
