Hibernate setMaxResults() with H2 SqlGrammarException

Question

I'm attempting to get a certain number of rows from the database given a certain user and a max amount. Here is what the code looks like currently:

@Override
public Collection<TestObject> findMaxByUser(User _user, int _max) { 
if (_max <= 0) {
  throw new IllegalArgumentException("max <= 0: " + _max);
}
Long rowCount = (Long)createCriteria()
    .add(Restrictions.eq("m_queryUser", _user))
    .setProjection(Projections.rowCount())
    .uniqueResult();

Collection<TestObject> results = createCriteria()
  .add(Restrictions.eq("m_queryUser", _user))
  .setFirstResult(1)
  .setMaxResults(_max)
  .list();
final int count = rowCount.intValue();
final int totalCount = count > results.size() 
    ? count : results.size();
return results;

This results in a org.hibernate.SQLGrammarException: could not prepare statement error.

The strange thing is, if I change DB implementations to Derby, the code works fine. But there's something goofy happening using H2 when I try to use .setMaxResults(). If I use .setFetchSize() instead it'll return all the results no problem, but going back to .setMaxResults() produced the above error.

Any help/information would be great.

It sounds like you are not using the right dialect...

Double check what it is set to.

hibernate.dialect=org.hibernate.dialect.H2Dialect
