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

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
{panel}
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

Criteria.setLockMode does not work correctly
--------------------------------------------
Key: HHH-5275
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5275
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.5.2, 3.5.3
Environment: Hibernate 3.5.2, Oracle 10 (using
org.hibernate.dialect.Oracle10gDialect
Reporter: Björn Moritz
Assignee: Steve Ebersole
Priority: Minor
Fix For: 4.0.1
Attachments: AnotherOracle10gDialect.java, My_Oracle10Dialect.java,
My_Oracle10Dialect.java, TestCase.zip
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.
