Chris Wilson commented on HHH-2308:
-----------------------------------
If you need this support in a stable release (3.3.2GA) you can use [our RitaCriteriaQuery
class|http://rita.wfplogistics.org/trac/browser/rita/src/org/wfp/rita/db/...]:
{code}
Criteria rl = session.createCriteria(RequestLine.class);
RitaCriteriaQuery rcq = new RitaCriteriaQuery(rl, m_Facade);
...
Criteria mo = session.createCriteria(rl, "movementsIn",
"mo", JoinFragment.INNER_JOIN);
rcq.setJoinRestriction(mo, Restrictions.eq("ownerCode",
Movement.OwnerCode.O));
...
List<RequestLine.Id> ids = rcq.list();
{code}
You'll probably want to change the RitaCriteriaQuery constructor to take a Session and
a SessionFactory instead of a DataFacade (which is our Session wrapper).
See [our RequestDao
class|http://rita.wfplogistics.org/trac/browser/rita/src/org/wfp/rita/dat...]
for more details and sample code.
Adding predicates to the join condition using Criteria Query
------------------------------------------------------------
Key: HHH-2308
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2308
Project: Hibernate Core
Issue Type: New Feature
Components: query-criteria
Affects Versions: 3.2.1
Environment: Linux Using MS SQLServer
Reporter: Ben Grant
Assignee: Steve Ebersole
Fix For: 3.5.0-Beta-3
Attachments: hibernate-3.3.2.GA-createAlias_withClause.patch,
hibernate-3.3.2.GA-createAlias_withClause.zip, hibernate-joinOn-sorted.ZIP,
hibernate-joinOn.ZIP, hibernate-outer-join-criteria-trunk.diff,
hibernate-outer-join-criteria.diff
I have two tables
Table A
||Col_1||Col_2||
|London| UK |
|Liverpool| UK |
| New York | USA |
Table B
||Col_1||Col_2|| Col_3||
| UK | Europe | 0
| USA | Americas | 1
Using the Criteria class, Restriction Class and FetchMode, Hibernate manages to create a
query that looks like this
select distinct top 2000
this_.Col_1 as y0_, TableB3_.Col2 as y1_
from TableA this_
left outer join TableB TableB3_ on this_.Col_2= TableB3_.Col_1
where TableB3_.Col_3=1
When really i need the query to be like this
select distinct top 2000
this_.Col_1 as y0_, TableB3_.Col2 as y1_
from TableA this_
left outer join TableB TableB3_ on this_.Col_2= TableB3_.Col_1 AND TableB3_.Col_3=1
currently their isn't any know way for hibernate to adjust or apply filters within
the join clause.
