Bill,

A trigger cannot display output.

Where would it go? A trigger does not run in an interactive session, it runs in the database independently, regardless of the presence or absence of a SQL Plus session.

I'm creating an AFTER CREATE ddl trigger:

CREATE OR REPLACE TRIGGER after_create_trg   after create
   on lwdev.schema
begin

   if sys.dictionary_obj_type='TABLE'

                 OR sys.dictionary_obj_type='SEQUENCE'

    then

                 begin
                                  dbms_output.put_line ('TEST');
                                  dbms_output.put_line 

(sys.dictionary_obj_name || ' , ' ||

sys.dictionary_obj_type);

                 exception
                                 when others then 
                                                 dbms_output.put_line 

('ERROR');

                 end;

   end if;
