INSERTING SRID of 8307 into SDO, which was converted from wkt

Question

Basically i have some SDO data that was converted to WKT text format and now i am trying to load it back using sqlldr. The problem seems to be that when you convert SDO_GEOMETRY to wkt it NULLS the SRID. We have a SRID of 8307. So the question is how do i insert this back into the SDO_GEOMETRY.
This is what i have tried and doesn't seem to work:
create or replace function convert_wkt_to_sdo ( p_data in clob )
return mdsys.sdo_geometry
as
p_data_final sdo_geometry;
begin
p_data_final := sdo_util.from_wktgeometry ( p_data );
return REGEXP_REPLACE (p_data_final, 'NULL SDO', '8307 SDO');
end;
Anyway of doing this?
In the sqlldr ctl file geo fields look like this
POINT_SPATIAL_DATA BOUNDFILLER,
POINT_SPATIAL EXPRESSION "conver_wkt_to_sdo( : POINT_SPATIAL_DATA)"

You might try something like:
create or replace function convert_wkt_to_sdo
    p_data in clob
return mdsys.sdo_geometry
as
    p_data_final sdo_geometry;
begin
    p_data_final := sdo_util.from_wktgeometry(p_data);
    p_data_final.sdo_srid := 8307;
    return p_data_final;
end;Instead of hard coding the SRID in the function as 8307, you might consider passing it as an argument instead (in which case you'd need to change the expression in your SQL*Loader control file).
Hope this helps
