I turned on server output using 'SET SERVEROUTPUT ON'. also opened 'dbms output' tab and connected to user. ( in sql developer > view > dbms output > plus sign > connect ) I have installed oracle 10g.
SET SERVEROUTPUT ON;
begin
dbms_output.put_line('Testing output');
end;
/
I'm getting only 'PL/SQL procedure successfully completed.' as ouput.
( It's duplicate question, but as i'm newbie and not have enough credits to comment on that question. so, ... )
DBMS_OUTPUT.ENABLErather thanSET SERVEROUTPUT ON?
