Sergey Pulyaev commented on HHH-2952:
-------------------------------------

This is possible, but :
if i already made some changes in several classes - why to implement slower logic if i can just can patch just one additional file instead?

> It would be very helpful to be able to reference non-root entities in Criteria SQL restrictions and projections using placeholders similar to {alias}. A very simple but uninteresting example:
> criteria.createAlias("group", "g");
> criteria.add(Restrictions.sqlRestriction("{g}.id=:groupId"));
