count() query on classes using EmbeddedId should not use id column tuple on Dialects which dont support non-distinct tuple counts ---------------------------------------------------------------------------------------------------------------------------------- Key: HHH-7165 URL: https://hibernate.onjira.com/browse/HHH-7165 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.1 Reporter: Ståle W. Pedersen Assignee: Steve Ebersole Fix For: 4.1.2 Attachments: column-count-test.tar.bz2 Time Spent: 0.75h When doing a count on a class mapped as EmbeddedId with multiple Id's the generated sql will fail on several db's (tested on MySQL/MariaDB) since hibernate generate a count sql containing all the id's. Hibernate creates a different (correct) sql on classes mapped with IdClass and multiple Id's. A simple test that verify the difference between the two: https://github.com/stalep/hibernate-orm/commit/54911765de7981ec9a2318fc99...
