Insert a UROWID into a ANYDATA table column

Hi,

Please note this is 1 of a few almost identical questions, but on different data types.

I need to take the value of a UROWID and store it within a ANYDATA data type column. Obviously, I also need to retrieve. First prize is to get it back as the original data type, but if this is not possible, to get it back as a clob data type.

I include an example I am working on, and would like help to get the script to work.
-------------------------------------------
--CREATE TABLE test_anydata (
--  fld anydata NOT NULL
--);

DECLARE
  c_fld CLOB := NULL;
  urowid_fld ROWID := 'AAAMaHAAEAAAAIHAAZ';
BEGIN
  DELETE FROM test_anydata;
--UROWID
  INSERT INTO test_anydata (fld) VALUES (anydata.converturowid(urowid_fld));
  c_fld := NULL;
  SELECT to_clob(anydata.accessurowid(fld)) INTO c_fld FROM test_anydata WHERE anydata.gettypename(fld) LIKE 'SYS.UROWID';
  Dbms_Output.put_line ('UROWID - ' || c_fld);
  commit;
END;
