Eric Dalquist commented on HHH-2879:
------------------------------------
Has there been any effort on this feature? I'd love to make better use of NaturalId
queries but have a few roadblocks. The biggest being HHH-4838 since most of our queries
are loading several objects and so even using the Criteria API we don't get the
natural id benefits. Having an explicit way to do natural id queries.
The other thought I had was wondering if it would be possible to tweak the Loader,
QueryParameters and a few other related classes to allow them to automatically determine
if a query from any source can be treated as a naturalid query. Considering the
restrictions already in place by CriteriaImpl.isLookupByNaturalKey I'm hoping it
wouldn't be too difficult.
I'd be more than happy to work on a feature patch if there is interest in applying
in.
add an actual api for loading an entity by natural candidate key
(mapped natural-id)

Key: HHH-2879
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2879
Project: Hibernate Core
Issue Type: Improvement
Components: core
Reporter: Steve Ebersole
Assignee: Steve Ebersole
Fix For: 3.x
Currently, natural-id "loading' is only available through some incomplete
criteria query hackery. Would like to expose a proper API for performing natural-id
loading.
Eventually would be great to have this coordinated with the effort to cleanup the Session
API and so have a unified way to load entities. (NOTE : the contract name I am using for
the time being is EntityLoadAccess, although i am not tied to this). - see HHH-2896
Something like:
Session.getNaturalKeyEntityLoadAccess( MyEntity.class ).get( key )
