---------------------------------
Does anybody have a quick solution to the ambiguous key problem in Hibernate UPDATE query
Other than Native query?????????
I can see only one solution that is to retrieve the Entity Object and set new value in it
and Merge that back.
hql update generate wrong sql with joined subclass hierarcy
-----------------------------------------------------------
Key: HHH-1657
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-1657
Project: Hibernate Core
Issue Type: Bug
Components: query-hql
Environment: Hibernate 3.2.0cr1, Hibernate 3.1.3
Reporter: Alexey Romanchuk
Assignee: Gail Badner
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
