Question on changing the owner of spatial datatype

Question

create table test4 (
COL1 NUMBER(38) NOT NULL,
COL14 SCOTT.SDO_GEOMETRY
) TABLESPACE USERS;
SQL> select table_owner, table_name FROM all_synonyms where synonym_name='SDO_GEOMETRY'
OMETRY';
TABLE_OWNER TABLE_NAME
SCOTT SDO_GEOMETRY
I want to change the owner of SDO_GEOMETRY to MDSYS. I know re-creating the table like "COL14 MDSYS.SDO_GEOMETRY" will get what i'm
looking for but is there a way to ALTER the table to achieve the same without re-creating it?
Thanks,
Rajesh

user11919950,
. . . .If you're just messing around on a test machine, then give this a spin:
-- "Identify obj# in table named obj$ for SDO_GEOMETRY owned by MDSYS
select
   obj#,
   t.OBJECT_NAME,
   u.USERNAME,
   o.OWNER#
from       sys.obj$ o,
   dba_users u,
   dba_objects t
where      u.USER_ID = o.OWNER# (+)
AND o.name = 'SDO_GEOMETRY'
AND o.owner# = 46
AND o.obj# = t.object_id;
      OBJ#   OBJECT_NAME  USERNAME   OWNER#
     45779  SDO_GEOMETRY  MDSYS      46
     48788  SDO_GEOMETRY  MDSYS      46
-- "identify owner#/user_id for SCOTT"
SELECT user_id FROM dba_users WHERE username = 'SCOTT'
   USER_ID
        54
-- "Change the username of one,both of those records from MDSYS to SCOTT"
-- "NOTE: untested SQL, but if it fails, just edit the table in Oracle Enterprise Manager"
UPDATE obj$ SET owner# = &ScottUserID WHERE obj# = &ObjNum;
COMMIT;
{code}
I've temporarily changed obj# values in this obj$ table to break associations between oracle objects that were throwing errors. I used Oracle Enterprise Manager's "view contents" form to view the obj$ table and to make those changes. See {message:id=4596120}
