How can I get NHibernate to hook up child objects automatically or bulk load

  • 0

How can I get NHibernate to hook up child objects automatically or bulk load children rather than lazy loading for each parent?

I have a large number of parent objects all of the same type. Each of them has two bags of child objects. As I need to load all the parents and children objects as quickly as possible, I use NHibernate to load all the objects and then loop all child objects and add them to relevant parent in code. I’m sure NHibernate has a much better way of doing this – but what is it?

    You can always use eager loading behavior of NHibernate to override its default behavior (Lazy Loading).
    Here is an article that discuss lazy loading and eagerly loading

    Take a look at the “Eagerly loading with HQL” part that shows how you can use HQL to eagerly load an object graph.

    However using eager loading can have a negative impact on performance specially if you are working with a lot of objects.
