Function sum with HQL language
<p>I have a question (sorry about my English, I'm learning)! 
I searched everywhere for how to use the command <code>sum(column)</code> with <code>HQL</code> hibernate language, but I can't find anything!</p>

<p>I can do it with <code>SQL</code> language. Example: </p>

<pre><code>SELECT sum(Column) FROM tablethatIwantthevalues;
</code></pre>

<p>but not with HQL Hibernate!</p>
