HQL UPDATE omits alias when referencing an entity
-------------------------------------------------

                 Key: HHH-5785
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5785
             Project: Hibernate Core
          Issue Type: Bug
    Affects Versions: 3.3.1
         Environment: Hibernate 3.3.1 in JBoss AS 5.1.0, org.hibernate.dialect.HSQLDialect
            Reporter: Ondrej Medek


HQL UPDATE:

UPDATE Lesson e SET e.state = 'N' WHERE EXISTS (SELECT 1 FROM LessonOrder lso WHERE lso.lesson = e)

produces wrong SQL:

update LESSON set lsn_state='N' where exists (select 1 from LESSON_ORDER lessonorde1_ where lessonorde1_.lsn_id=lsn_id)

since in the database exists columns if the same name: LESSON.lsn_id and LESSON_ORDER.lsn_id. The problem is, that Hibernate omits the alias "e" in the SQL. When I make a little different query:

UPDATE Lesson e SET e.state = 'N' WHERE EXISTS (SELECT 1 FROM LessonOrder lso WHERE lso.lesson.id = e.id)

then the resulting SQL is right:

update LESSON set lsn_state='N' where exists (select 1 from LESSON_ORDER lessonorde1_ where lessonorde1_.lsn_id=LESSON.lsn_id)

However, I think the Hibernate should not omit the alias "e" in either case.
