Err, I can’t think of better title. Basically I have a class called MarketGroups, this has a child collection Markgroups that has a collection of MarketTypes and MarketTypes has a collection of MetaGroups.

I would like to be able to, in one query, load the Parent, and only return Child MarketGroups that have MarketTypes with one specific MetaGroup in its MetaGroup collection.

I am aware of this question: Filter child collection returned with Aggregate Root using Nhibernate but is not the solution I’m looking for, I want to do this in code ideally as one query, but I wouldn’t mind splitting it.

🙂

  1. Unless you restrict the children that are loaded by default (using the method you linked to) you’ll have to load the Parent in one query and the children in another. AFAIK there’s no way to query an object and have only certain children loaded.

    You could always use MultiQuery to submit them at the same time mind you.

    HQL something like (this may be missing the mark a bit):

                select                 mt             from                  MarketGroup mg             inner join                 mg.MarketTypes mt             inner join                 mt.MetaGroups mg             where                 mg.ID=12312 and mg.ID=3214123
