title: Is ObjectDB JPQL different from normal JPQL
body: <p>I was discussing with someone about comparisons in JPQL, I gave him this link, <a href="http://www.objectdb.com/java/jpa/query/jpql/comparison" rel="nofollow">http://www.objectdb.com/java/jpa/query/jpql/comparison</a>, I think that ObjectDB uses the normal JPQL and so it sufficed the question. But someone told me that it is ObjectDB's JPQL so it is not useful, to a degree. Is this true because it doesn't seem that way in the link.</p>
