Can you rephrase your question? Do you already have a class, and you want to create an instance of it from an arbitrary piece of HQL or SQL? Also, can you correct your query? There's no relation between tra_salary and any other table, so that query is going to produce a full cross-join, and I very much doubt that that's what you want.
But briefly, assumng that you've mapped your classes and so on, the sort of HQL code you're looking for is
Code:
select e
from Employee e
join e.Feature f
where e.Name = :Name
