Incorrect delete handling ------------------------- Key: HHH-3083 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3083 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.5 Environment: 3.2.5.ga Reporter: Krashan Brahmanjara When user try to delete not existing row from database see long exception message. Real databases like Informix report status=0 and don't report any error in this case and users probably expect the same from Hibernate. I think that should be rather NotFoundException than org.hibernate.StaleStateException etc. I see this error also when hibernate.jdbc.batch_size is 0 a Current exception trace in this case 2008-01-24 15:48:43 org.hibernate.event.def.AbstractFlushingEventListener performExecutions SEVERE: Could not synchronize database state with session org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1 at org.hibernate.jdbc.Expectations$BasicExpectation.checkBatched(Expectations.java:61) at org.hibernate.jdbc.Expectations$BasicExpectation.verifyOutcome(Expectations.java:46) at org.hibernate.jdbc.NonBatchingBatcher.addToBatch(NonBatchingBatcher.java:24) at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2520) at org.hibernate.persister.entity.AbstractEntityPersister.delete(AbstractEntityPersister.java:2697) at org.hibernate.action.EntityDeleteAction.execute(EntityDeleteAction.java:74) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:234) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:146) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:298) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:338) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:106) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
