[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2139) Iterating a joined-subclass query

Iterating a joined-subclass query --------------------------------- Key: HHH-2139 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2139 Project: Hibernate3 Type: Bug

Components: query-hql Versions: 3.1.3 Environment: Hibernate 3.1.3, PostrgreSQL 8.0.3 Reporter: Flavio Suguimoto Priority: Critical

In a joined-subclass structure when trying to use query.iterate(), to use cache and lazy, hibernate translate the query "from Activation activation where activation.class = Activation" to an mal-formed SQL query. The SQL query string that it creates is "select activation0_.id as col_0_0_ from activation activation0_ where case when activation0_1_.fk_id_activation is not null then 1 when activation0_.id is not null then 0 end=0".
