Hello Hibernate folks,

This is my first posting here, and i hope i'm not being totally noobish with the following question.

I've got the following code:

Code:
Criteria crit = this.getSession().createCriteria(MainClass.class);


The MainClass is linked to other classes (let's call them "MemberClass" -> member name "memberClasses") which themselves contain other classes (let's call them "subClasses" <- member name)


I want to get all MainClass objects which own one or more memberClasses which own one or more subClasses with the id "someRandomId":

Code:
crit = crit.createCriteria("memberClasses").createCriteria("subClasses").add(Restrictions.eq("id", someRandomId));



This one works really well, but it doesn't allow me to add

Code:
crit = crit.createCriteria("memberClasses").createCriteria("subClasses2").add(Restrictions.eq("id", someOtherRandomId));


to the above code because i've already changed the associationPath to "memberClasses->subClasses". Is there a way to get back to "memberClasses" and then go to "memberClasses->subClasses2" or any other way to reach my desired goal? ;)

thanks,
Marc

How about this:

Code:
Criteria base = getSession().createCriteria(MainClass.class)
   .createCriteria("memberClasses");

Criteria one = base.createCriteria("subClasses")
   .add(Restictions.idEq(12);

Criteria two = base.createCriteria("subClasses2")
   .add(Restrictions.idEq(13);

Marc,

You have to create an Alias.
Do something like

Code:
crit=crit.createAlias("subClasses","a");
crit=crit.createAlias("subClasses2","b");
crit=crit.add(Restrictions.eq("a.id", someRandomId);
crit=crit.add(Restrictions.eq("b.id", someOtherRandomId);


I hope this helps
Daniel
