Question

I’m using Hibernate 3.2, and using criteria to build a query. I’d like to add and “order by” for a many-to-one association, but I don’t see how that can be done.
The Hibernate query would end up looking like this, I guess:

select t1.a, t1.b, t1.c, t2.dd, t2.ee
from t1
inner join t2 on t1.a = t2.aa
order by t2.dd   <-- need to add this

I’ve tried criteria.addOrder(“assnName.propertyName”) but it doesn’t work. I know it can be done for normal properties. Am I missing something?

Answer 1

Ok, found the answer. I tried something that I didn’t think would work, but to my surprise did. I was trying this:

Criteria criteria = super.getSession().createCriteria(WipDiscreteJob.class);

criteria.addOrder(Order.asc("assnName.propertyName"))

but what actually worked was:

Criteria criteria = super.getSession().createCriteria(WipDiscreteJob.class);
Criteria assnCrit = criteria.createCriteria("assnName");

assnCrit.addOrder(Order.asc("propertyName"));

I had made the assumption that the addOrder() method was only usable on the main criteria and not on any association criteria.
