]
Douglas Ferguson commented on HHH-2049:
---------------------------------------
We have a library that uses the criteria api to build up a pretty complicated filter. We
had a change in our data model recently that requires us to use a "left join on id1 =
id2 AND id1 = ?"
Is there a way to accomplish this with the criteria api?
If not, if we were going to create a patch or some how create an workaround, can anybody
point us in the right direction?
LEFT OUTER JOIN subcriteria filters children
--------------------------------------------
Key: HHH-2049
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2049
Project: Hibernate Core
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.1.3, 3.2.0.cr4
Environment: Hibernate 3.1.3/3.2.0rc4, hsqldb 1.8
Reporter: Mattias Jiderhamn
Attachments: SubCriteriaTestCase.zip
When using the Criteria API with LEFT OUTER JOIN to add criterias to the children, i.e.
criteria.createCriteria("children", JoinFragment.LEFT_OUTER_JOIN)
the child collections will only contain those children matching the criteria. (Even when
*not* using any Filters).
The attached testcase (also found here:
http://forum.hibernate.org/viewtopic.php?p=2320786) will explain it in more detail.
