title: One line IF condition in PL/SQL
body: <p>It's possible to write one line if's in pl/sql? I'm just curious.</p>
  
  <p>I want to write this snippet:</p>
  
  <pre><code>IF ( i.DECISAO_AT = 'S')
  THEN 'PA'
  ELSE 'I'
  END IF;
  </code></pre>
  
  <p>And I want to know if it's possible to write it in one line, just like java. Like this:</p>
  
  <pre><code>IF ( i.DECISAO_AT = 'S') ? 'PA' : 'I' ;
  </code></pre>
  
  <p>Thanks!   </p>
