How to delete multiple db entities with Nhibernate?

Question

What is the best practice for this problem? Is there any batching features built-in?

Sample code:

using (ITransaction transaction = _session.BeginTransa         


        

Answer 1

you can Use HQL to delete multiple objects

Look for delete here - for session.delete example

HQL DELETE example (you can use IN with HQL):

ISession session = sessionFactory.OpenSession();
ITransaction tx = session.BeginTransaction();

String hqlDelete = "delete Customer c where c.name = :oldName";
// or String hqlDelete = "delete Customer where name = :oldName";
int deletedEntities = session.CreateQuery( hqlDelete )
        .SetString( "oldName", oldName )
        .ExecuteUpdate();
tx.Commit();
session.Close();
