title: Why no output when PLSQL Anonymous block completes?
body: <p>I'm just getting into PL/SQL, and I tried to run the following code, and I am getting <strong>anonymous block completed</strong>, but I think I should be getting <strong>Testing output</strong>. Does any know what I am doing wrong?</p>
  
  <pre><code>DECLARE
     message varchar2(20) := 'Testing output';
  BEGIN
     dbms_output.put_line(message);
  END;
  /
  </code></pre>
