[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5275) Criteria.setLockMode does not work correctly

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=44760#comment-44760 ] 

Steve Ebersole commented on HHH-5275:
-------------------------------------

So based on my experiments here is what I see...

# get/load work as before.
# {{Criteria#setLockMode}} did not work, neither form
# {{Query#setLockMode}} did not work

Jakob, with regard to the difference between 
* {{query.setLockMode("cat", LockMode.UPGRADE)}} and
* {{query.setLockOptions(new LockOptions(LockMode.UPGRADE))}}

I think that is valid actually.  IMO, if you want to lock just a specific table you would instead say this in the second form:
* {{query.setLockOptions(new LockOptions().setAliasSpecificLockMode("cat",LockMode.UPGRADE))}}

This does not work either, but that is the behavior I will shoot for

>          Issue Type: Bug

>         Environment: Hibernate 3.5.2, Oracle 10 (using org.hibernate.dialect.Oracle10gDialect

> The LockMode set via Criteria.setLockMode does not generate a ' for update' SQL statement. In the org.hibernate.dialect.Dialect class only the LockOptions are used for determining a possible addition to the SQL statement if using pessimistic locking. This behaviour is different from Hibernate 3.1.3.
> In the supplied TestCase two threads are reading the same database record; one of those threads should use pessimistic locking thereby blocking the other thread. But both threads can read the database record causing the test to fail.
