 Post subject: Best way to get an arbitrary sequence value?

The requirments state that one of my objects must have a business key that defaults to a value generated by a specific Oracle sequence.

What's the most appropriate way to do this with NHibernate?

1) Bypass NHibernate and execute and ADO.NET statement directly

2) Use ISession.CreateSQLQuery()? What should I use as the parameters?

3) Manually create and configure an NHibernate.Id.SequenceGenerator instance.

Any help would be appreciated. Thanks.

I don't know if this is the best way, but this is how I'm doing it.


Code:
         using (IDbConnection con = _sessionFactory.ConnectionProvider.GetConnection())
         {
            IDbCommand cmd = con.CreateCommand();
            cmd.CommandText = "SELECT myschema.my_seq.NEXTVAL FROM DUAL";
            result = cmd.ExecuteScalar().ToString();
         }
