title: DBMS_OUTPUT.NEW_LINE and DBMS_OUTPUT.NEW_LINE() difference?
body: <p>What is the difference between these two statements?</p>
  
  <pre><code>dbms_output.new_line(); // with no parameters.
  dbms_output.new_line;    // with no parameters,no round brackets
  </code></pre>
  
  <p>If there is function overloading,even for that close and open brackets are required after function name.</p>
