title: How can I get my sequence nextval using QueryDSL?
body: <p>I was digging around to find a solution to this problem using Oracle and the only thing I was able to find so far was the method <strong><em>nextval</em></strong> from <strong><em>com.mysema.query.sql.SQLExpression</em></strong>, but yet I'm not quite sure how to use it and didn't find anything at all even in the documentation.</p>
  
  <p>Is there someone who had to use it and also have it figured out?</p>
