Hibernate new keyword with distinct

问题:

I need to take hql that is currently :

select distinct a from Asset as a where ...

and change it to

select new com.org.AssetDTO(a.id, a.address, a.status) from Asset as a where ...

My problem is with the distinct keyword. Where does it belong in an hql query where you're using the new Object query type. One thought was to use a sub-select and have my distinct there. I've tried adding distinct a.id but that doesn't work.

Ok for anyone interested the proper syntax is

select distinct new com.org.AssetDTO(a.id, a.address, a.status) from Asset as a where ...
