---------------------------------------

Hello, i have found the same problem trying to delete a hierarchy having a composite primary key,  the HQL statement that I am trying to execute is the following

delete from  Employee _emp where concat(_emp.lastName,'_$$_',_emp.firstName)  in(:values)

in my case case "Employee" extends "Person" and the SQL query generated to fill the temporary table used for bulk delete is the following:

insert  into
        HT_employee
        select
            employee0_.`LASTNAME` as `LASTNAME`,
            employee0_.`FIRSTNAME` as `FIRSTNAME` 
        from
            `employee` employee0_ 
        inner join
            `person` employee0_1_ 
                on employee0_.`LASTNAME`=employee0_1_.`LASTNAME` 
                and employee0_.`FIRSTNAME`=employee0_1_.`FIRSTNAME` 
        where
            concat(`LASTNAME`, '_$$_', `FIRSTNAME`) in (
                ?
            )

Obviously the problem is caused by the missing of the correct entity alias into the concat function of the where clause.

> Let suppose that we have two joined subclass entities: Parent (id PK) and Child (id PK) that mapped with joined subclass method.
> When I try to update Child by id with hql:
> update Child c set c.field = 'value' where c.id = 1234
> hibernate generates joined tables like 
> insert into HT_parent select child0_.id as id from child child0_ inner join parent child0_1_ on child0_.id=child0_1_.id  wher id in = 1234
> look at last condition. hibernate use id WITH OUT tables alias that cause sql exception: column reference "id" is ambiguous
