How to get added columns in the after DDL trigger?

Question

As title, I want to get information, like name/type/.., about the added columns by sql statement "alter table *** add (***)" in the after ddl trigger. But looks like dba_tab_columns view doesn't include the added columns.
Thanks

Hi
Hi try other versions of the trigger like
create or replace trigger addl_trigger
after alter on schema
declare
TYPE attrs_cur IS REF CURSOR;
m_cur attrs_cur;
m_event varchar2(50);
m_user varchar2(50);
m_owner varchar2(50);
m_user1 varchar2(50);
m_type varchar2(50);
m_name varchar2(50);
m_column varchar2(50);
m_cnt NUMBER;
m_stmt varchar2(512);
number_of_modified_objects BINARY_INTEGER;
t ora_name_list_t;
begin
m_event:=ora_sysevent;
m_user:=SYS_CONTEXT('USERENV','SESSION_USER');
m_user1:=ora_login_user;
m_owner:=ora_dict_obj_owner;
m_type:=ora_dict_obj_type;
m_name:=ora_dict_obj_name;
if (m_type='TABLE' and m_event='ALTER')
then
          execute immediate 'select count(*) from dba_tab_columns where owner=:1 and table_name=:2' into m_cnt
          using m_owner,m_name;
          insert into log values (m_cnt);
          dbms_output.put_line('->'||m_cnt);
          OPEN m_cur FOR 'select c.name from sys.col$ c, sys.obj$ o, sys.user$ u where o.obj# = c.obj# and o.owner# = u.user# and u.name=:1 and o.name=:2' using m_owner,m_name;
          LOOP
                    FETCH m_cur INTO m_stmt;
                    EXIT WHEN m_cur%NOTFOUND;
                    insert into log values (m_stmt);
                    --dbms_output.put_line(m_stmt||'**************');
                    END LOOP;
end if;
but all versions continue to insert only the already existing columns. I think that Oracle actualize the dictionary first after this system event.
