creating temporary table for bulk delete will commit current transaction in managed environment such as J2EE ------------------------------------------------------------------------------------------------------------ Key: HHH-1361 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1361 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.1 Environment: J2EE container; Oracle Reporter: Jifeng Liu Assignee: Steve Ebersole Fix For: 3.1.1 Attachments: hibernate.cfg.xml, stacktrace.txt I have a table mapping with joined-subclass as following. When I execute bulk delete statement: session.createQuery( "delete from Job j where j.status = :status" ) .setString( "status", pStatus ) .executeUpdate() Hibernate will automatically create a temporary table called HT_Job to store job ids. This will cause current database transaction committed. Because I am using J2EE container managed transaction (CMT), this commit behavior is not good. And I also lose opportunity to rollback the transaction. <class name="com.senior.bll.shared.jobs.Job" table="job" rowid="rowid"> <id name="id" column="job_id"/> <version name="updateDateTime" column="update_date_time" type="oracle_date"></version> <property name="type" column="job_type"/> <joined-subclass name="com.senior.bll.entity.constituent.messaging.schedules.MessageJob" table="message_job_data" > <key column="job_id" /> <property name="queryId" column="query_id"/> </joined-subclass> </class>
