How to suppress SCHEMA_OWNER when using DBMS_METADATA.GET_DDL

Question

Hi,
I was wondering, is it possible to suppress the owner when using dbms_metadata.get_ddl?
SQL> select * from v$version where rownum = 1
BANNER                                                         
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi
SQL> exec dbms_metadata.set_transform_param (dbms_metadata.session_transform,'SEGMENT_ATTRIBUTES',false)
SQL> select dbms_metadata.get_ddl('TABLE','EMP') from dual
DBMS_METADATA.GET_DDL('TABLE','EMP')                                           
  CREATE TABLE "SCOTT"."EMP"                                                   
   (     "EMPNO" NUMBER(4,0) NOT NULL ENABLE,                                      
     "ENAME" VARCHAR2(10),                                                         
     "JOB" VARCHAR2(9),                                                            
     "MGR" NUMBER(4,0),                                                            
     "HIREDATE" DATE,                                                              
     "SAL" NUMBER(7,2),                                                            
     "COMM" NUMBER(7,2),                                                           
     "DEPTNO" NUMBER(2,0)                                                          
   )I would like to get rid of the "SCOTT". Alternatively to change it into something else.
Is that possible, without post processing the output, that is?
Regards
Peter

Hi Karthick,
I was afraid that would be the answer. It can be done, but it seems rather convoluted:
SQL> create or replace function get_table_ddl(table_name    varchar2
                                        ,schema        varchar2 default user
                                        ,new_owner     varchar2 default null)
   return clob
is
   v_handle        number;
   v_transhandle   number;
   v_ddl           clob;
begin
   v_handle := dbms_metadata.open('TABLE');
   dbms_metadata.set_filter(v_handle, 'SCHEMA', schema);
   dbms_metadata.set_filter(v_handle, 'NAME', table_name);
   v_transhandle := dbms_metadata.add_transform(v_handle, 'MODIFY');
   dbms_metadata.set_remap_param(v_transhandle,'REMAP_SCHEMA',schema,new_owner);
   v_transhandle := dbms_metadata.add_transform(v_handle, 'DDL');
   dbms_metadata.set_transform_param(v_transhandle,'SEGMENT_ATTRIBUTES',false);
   v_ddl := dbms_metadata.fetch_clob(v_handle);
   dbms_metadata.close(v_handle);
   return v_ddl;
end;
Function created.
SQL> select get_table_ddl('EMP') from dual
GET_TABLE_DDL('EMP')                                                           
  CREATE TABLE "EMP"                                                           
   (     "EMPNO" NUMBER(4,0) NOT NULL ENABLE,                                      
     "ENAME" VARCHAR2(10),                                                         
     "JOB" VARCHAR2(9),                                                            
     "MGR" NUMBER(4,0),                                                            
     "HIREDATE" DATE,                                                              
     "SAL" NUMBER(7,2),                                                            
     "COMM" NUMBER(7,2),                                                           
     "DEPTNO" NUMBER(2,0)                                                          
1 row selected.Regards
