Batch Update in NHibernate

Question

Does batch update command exist in NHibernate? As far as I am aware it doesn\'t. So what\'s the best way to handle this situation? I would like to do the following:

Answer 1

Starting NHibernate 3.2 batch jobs have improvements which minimizes database roundtrips. More information can be found on HunabKu blog. Here is example from it - these batch updates do only 6 roundtrips:

using (ISession s = OpenSession())
using (s.BeginTransaction())
{
    for (int i = 0; i < 12; i++)
    {
        var user = new User {UserName = "user-" + i};
        var group = new Group {Name = "group-" + i};
        s.Save(user);
        s.Save(group);
        user.AddMembership(group);
    }
    s.Transaction.Commit();
}
