[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-16) Explicit joins on unrelated classes

[Steve Ebersole (JIRA)]

     [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-16?page=all ]

Steve Ebersole updated HHH-16:
------------------------------

    Fix Version: 3.2.2
                     (was: 3.2.1)

not going to be done for 3.2.1; more than likely this and the requisite translator changes actually will force a 3.3 line...

> It would be nice to be able to do explicit joins on unrelated classes with HQL:
> (hope this renders correctly)
>           select empl, phone
>             from org.example.Employee empl
>  left outer join org.example.PhoneBook phone
>               on phone.lastName = empl.lastName
>              and phone.firstName = empl.firstName
>            where empl.salaryGrade > 10
> Note that this would also implicity solve HB-1089 because you could list join criteria that match what Hibernate would have chosen anyway (i.e., list a many-to-one relationship as a criteria explicitly).
> Syntactically this could be disambiguated from the existing join syntax because the token after "join" is a class name rather than a property name.
