Constant expresion in select count phrase
-----------------------------------------

                 Key: EJB-412
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-412
             Project: Hibernate Entity Manager
          Issue Type: Bug
    Affects Versions: 3.3.1.GA
            Reporter: Maciej Szulik


I found that using constant expression in select count phrase is illegal.

>From DB point of view using
select count(1) from ...

is much more efficient than
select count(field) from ...
