Subject [jira] Commented: (OPENJPA-1092) enable test case for jpql
Date Fri, 22 May 2009 18:22:45 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712192#action_12712192
] 

Michael Dick commented on OPENJPA-1092:
---------------------------------------

I'm guessing it's actually OPENJPA-817 which preserves the order of statements when using
constraint update manager. Absent any other information to the contrary we'll execute in the
order we were called (deletes, updates, and inserts are grouped - but it's still better than
no ordering).

> Currently TestEJBQueryInterface is excluded.
> To enable it, just a little change is needed: invoking em.flush() after every em.persist().
> The test case wants to get the result depends on the order of the creation of the entity
instance. but we (as well as most other JPA implementations) don't care about the creation
order of java instances because the insertion happens when the transaction is committed or
flush is invoked. So adding "em.flush()" after "em.persist()" will resolve the problem.
