I have an object that is mapped to have a set of objects, very simple. However, what I really want to do is put some criteria on that mapping. Here’s the current mapping:

    <set name='ops' inverse='true' cascade='all, delete-orphan'>         <key column='cityblock_id' on-delete='cascade'/>         <one-to-many class='com.tamedtornado.data.Operation'/>     </set>

Now, instead of just getting all associated ops, I want to just get ops that haven’t completed, or have, or whatever. The Hibernate docs are very quiet on this, although some old forum posts have shown me a little. You can apparently use a sql-query tag, but that’s also not what I want to do.

Is there anyway to do this with an HQL query? I just want to narrow the results with a simple query and have a few collection maps, like active_ops and completed_ops, etc.

Cheers, Jason

  1. Under 6.2. Collection mappings in the Hibernate docs you will find that you can use a WHERE clause on any collection mapping:

    where (optional) specify an arbitrary SQL WHERE condition to be used when retrieving or removing the collection (useful if the collection should contain only a subset of the available data)

    You said that you want to use a HQL Query but I don’t think that is possible. But as you only have to specify a simple WHERE clause in your mapping there isn’t really much difference, between HQL and ‘real’ SQL.
