Incorrect SQL emitted for EJB query involving COUNT()
-----------------------------------------------------

         Key: EJB-251
         URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-251
     Project: Hibernate Entity Manager
        Type: Bug

  Components: EntityManager  
    Versions: 3.2.0.ga    
 Environment: Hibernate 3.2 / MySQL 4.1.xx
    Reporter: Manuel Mall


If you have an entity with a composite id and query it like:

select count(e) from Entity e

the emitted SQL looks like

SELECT COUNT(e.id1, e.id2) FROM Entity

However, this is at least according to MySQL invalid SQL as the COUNT function can have only one argument.
