title: JPA Named Query "o"?
body: <p>I am just curious what the <code>o</code> stands for when I am trying to query.</p>
  
  <p>By default my query is coming out as<br>
  <code>@NamedQuery (name="newName" query=SELECT o FROM tableView o)</code></p>
  
  <p>I am just curious what the <code>o</code> stands for. I have seen several instances of using the letter <code>x</code> and <code>c</code> as well. Just wondering what the difference, if any. Also, why can't I just use a <code>*</code> to select and entire row?</p>
