Hello,

I have got two tables in myDataBase, with a relation one-to-many (Parent/Child).

In my class Parent, I have an attribute, called childrens, which is the type List<Child>.

I want use hibernate, and load all the childrens in the attribute, but I don't have any column index in the table CHILD.

How can I create an artifical index?

Thanks

You can do that with a Set instead of a List. Since both implement the Collection interface you can iterate through a set just like a list. The default java object that implements the Set interface is HashSet.
