I have a parent child relationship. I am using a Criteria to select a list of parents. Currently, my database is issued a query with a join between my parent and child tables.

Is it possible to delay the selection of children until I actually touch the Children collection for each parent?

Instead of:

Code:

select *
from parent
left join children ...
where ...

use:

Code:

select *
from parent
where ...

and when I touch the Children collection:

Code:

select *
from child
where parentid = ?

Nevermind, I've just discovered lazy loading!
