docs: Sets the statement ORDER BY clause in the form of<br><br>
  <code>"ORDER BY &lt;property&gt; [ASC | DESC]"</code>

  e.g. "type ASC, lastModifiedDateTime DESC". The "ORDER BY " keyword will be
  ignored.
  @param orderBy the statement order by without "ORDER BY"
  @return a reference to this object
