How to delete set of entities by id list?

Question

How can i do something like this

Session
.CreateQuery("delete from People where People.Id in (:idList)")
.SetParameter("idList", idList)
.ExecuteUpdate()

but without HQL?

Answer 1

You can do this:

foreach(var item in idList)
{
    Session.Delete(Session.Load<People>(item));
}

and to improve performance of this set batch size to 20 like this in configurations:

<property name="adonet.batch_size">20</property>

this behavior existing by default in Nhibernate 3.2

Answer 2

As far as I know there is no Fluent Nhibernate syntax for deleting entities. I also used HQL (or even SQL) when I wanted to delete.

Answer 3

There is an example here that might do what you need. It is one of the overloads of session.Delete
