[Hibernate-JIRA] Commented: (HHH-1697) OracleDialect fails to recognize sequence accessible through syonyms when validating schema

by Roland Hofmann (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1697?page=c... ] Roland Hofmann commented on HHH-1697: ------------------------------------- Following there is a little bit adapted version of the first fixxing. The precondition is that the synonym names must be equals with the sequence name in the view. Normal this is the case. public String getQuerySequencesString() { return "select sequence_name from user_sequences " + "union " + "select synonym_name from user_synonyms us " + "where exists ( select 1 from all_sequences aseq where us.synonym_name = aseq.sequence_name)"; } With this solution i get the informations not from all objects but from all sequences. > OracleDialect fails to recognize sequence accessible through syonyms when validating schema > ------------------------------------------------------------------------------------------- > > Key: HHH-1697 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1697 > Project: Hibernate3 > Issue Type: Bug > Environment: Hibernate 3.1.2, Hibernate 3.1.3 Oracle 10g > Reporter: Bjørn Bjerkeli > Priority: Minor > Attachments: Oracle9Dialect.java > > > The Dialect implementations in OracleDialect and Oracle9Dialect fails to recognize sequences upon validation when they are accesssed through synonyms > because the user_sequences table will not create when the sequence is acced through a synonym.

[Hibernate-JIRA] Created: (EJB-329) Get persistence unit name from EntityManager and EntityManagerFactory

by Emmanuel Bernard (JIRA)

Get persistence unit name from EntityManager and EntityManagerFactory --------------------------------------------------------------------- Key: EJB-329 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-329 Project: Hibernate Entity Manager Issue Type: New Feature Components: EntityManager Reporter: Emmanuel Bernard Assignee: Max Rydahl Andersen Priority: Minor Max asked for PU name retrieval in EM and EMF. To inject them in PersistenceException and logs, is problematic since not all Hibernate exceptions/logs are catched and rethrown by EM and EMF so it would not be complete. Providing programmatic access to the PU name is doable but for what use case?

by Shyamsunder (JIRA)

Typo in Hibernate API docs - SessionFactory class ------------------------------------------------- Key: HHH-3122 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3122 Project: Hibernate3 Issue Type: Patch Components: documentation Affects Versions: 3.2.6, 3.2.5 Environment: Hibernate Core Java Doc Reporter: Shyamsunder When I was referring to SessionFactory class java doc in Hibernate API at http://www.hibernate.org/hib_docs/v3/api/org/hibernate/SessionFactory.html I found that the following two methods that return Session. Session getCurrentSession() Session openSession() //it has three more overloaded method The link given to Session should be http://www.hibernate.org/hib_docs/v3/api/org/hibernate/Session.html instead of http://www.hibernate.org/hib_docs/v3/api/org/hibernate/classic/Session.html The same typo is produced in latest release, i.e., hibernate-3.2.6.ga API docs.
