Hibernate query for multiple items in a collection

Question

I have a data model that looks something like this:

public class Item {
    private List attributes;
    // other stuff
}

public class Item         


        

Answer 1

Use LEFT_OUTER_JOIN to prevent "WHERE x = 1 AND x = 2" kind of issue

CreateAlias("itemAttributes", "ia", JoinType.LEFT_OUTER_JOIN)
