Manuel Mall updated HHH-2266:
-----------------------------
Attachment: model.zip
I have attached a ZIP file containing two Java files, one being the entity class and the other being the composite id class for the entity.
The query in question is simply:
select count(e) from CertificateTypeField e
The Hibernate emitted SQL is:
select count((certificat0_.code, certificat0_.name)) as col_0_0_ from CertificateTypeFields certificat0_
Hope this helps

> 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.
