NamingStrategy.classToTableName receives only class name, not a fully qualified name as stated in javadoc --------------------------------------------------------------------------------------------------------- Key: HHH-1976 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1976 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3, 3.2.0.cr2 Reporter: Lóránt Pintér I have a custom NamingStrategy that overrides classToTableName in EJB3NamingStrategy. Prior to upgrading to Hibernate 3.1.3, my NamingStrategy implementation received the correct classnames as documented in the javadoc at http://www.hibernate.org/hib_docs/v3/api/org/hibernate/cfg/NamingStrategy... Since then, it only receives the name of the class without the package specification. I tried upgrading to 3.2.0.cr2, but it didn't help. -- 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

[Hibernate-JIRA] Created: (HHH-2150) There are too many columns in the select statement with the Criteria API

by Slawek Trybus (JIRA)

There are too many columns in the select statement with the Criteria API ------------------------------------------------------------------------ Key: HHH-2150 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2150 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.2.0.ga Environment: Hibernate 3.2.0.cr2 PostgreSQL 8.1.3 Reporter: Slawek Trybus Using Criteria API brings on enclosing all columns from joined tables in generated select statement. It has big efficiency impact on DB especially if there are many joined tables (with many columns each) in a query. There is columns' limitation possible with the Projections API usage, but it makes received objects not fully fledged Hibernate entity objects. It would be good to have posibility to limit amount of columns in select statement to ones connected to entity we are interested in. There is available short discusion about this issue in the forum: http://forum.hibernate.org/viewtopic.php?t=965818 -- 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

[Hibernate-JIRA] Created: (ANN-472) @UniqueConstraint declaration is not friendly towards inheritance or reflection

by Ted Bergeron (JIRA)

@UniqueConstraint declaration is not friendly towards inheritance or reflection ------------------------------------------------------------------------------- Key: ANN-472 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-472 Project: Hibernate Annotations Type: Improvement Versions: 3.2.0.ga Environment: Hibernate 3.2 GA Reporter: Ted Bergeron The current way to define a composite unique constraint is limiting. @Table(name="tbl_sky", uniqueConstraints = {@UniqueConstraint(columnNames={"month", "day"})} ) Suppose I have an abstract base class called A that gives me Id and Name, subclassed by abstract class B that gives me Customer. Then I have many concrete classes that subclass B. For all of these, I'd want the combination of Name and Customer to be unique. As I do not use @Table with abstract base classes, I currently have to repeat: uniqueConstraints = {@UniqueConstraint(columnNames={"name", "customer_id"})} on all concrete classes. If we had an alternate way to define these constraints at the property level (as XDoclet did with hibernate 2), I could define this in the base classes and inherit the constraint declaration. The other need is that I would like to use reflection to scan the properties and apply proper validations in the view layer. With @Column(unique = true) this is easy to do. The view layer makes an AJAX call and all is well. For a composite constraint, it does not work well currently. -- 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

[Hibernate-JIRA] Created: (HHH-2319) StatelessInterceptor

by Max Rydahl Andersen (JIRA)

StatelessInterceptor -------------------- Key: HHH-2319 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2319 Project: Hibernate3 Type: New Feature Components: core Versions: 3.2.1 Reporter: Max Rydahl Andersen It would make sense to have an Interceptor for StatelessSession to solve the following usecases: Log/adjust SQL: onPrepareStatement Proper entityname handling: instantiate/getEntity Maybe also tx interaction: afterTransationBegin/beforeTransactionCompletion/afterTransactionCompletion Technically it could be solved by just allowing to pass in a normal interceptor to a StatelessSession and just document that the state oriented callbacks will not be called. Alternatively we can create a StatelessInterceptor that only implement the releavant methods and wrap that instance into an internal Interceptor. -- 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

[Hibernate-JIRA] Created: (HHH-2007) Hibernate doesn't support optional one-to-one associations

by Andrei Iltchenko (JIRA)

Hibernate doesn't support optional one-to-one associations ---------------------------------------------------------- Key: HHH-2007 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2007 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Reporter: Andrei Iltchenko Hibernate doesn't properly support optional one-to-one associations, e.g. Person (0..1) -- (0..1) Passport. The Hibernate books and reference all talk of two ways of mapping one-to-one associations: 1. using a many-to-one fk association with a unique constraint on the fk; 2. using a pk association. the trouble with both of them is that they enforce the mandatory property of an association end, which sometimes is not desirable. The first way enforces the mandatory property with the uniqueness constraint on the fk, the other by using the fact that one table's pk is its fk. I tried to see if I could adapt the 1st way of representing one-to-ones to support optional association ends. What I did was simply remove the unique and not null constrains from DDL generated (without removing it it would be impossible to have a Person record that doesn't reference a Passport record): from CREATE TABLE Person ( PassUniqueId VARCHAR (32) NOT NULL, version INTEGER NOT NULL, uniqueId VARCHAR (32) NOT NULL, name VARCHAR (40) NULL, PRIMARY KEY (uniqueId), UNIQUE(PassUniqueId), FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId) ); to CREATE TABLE Person ( PassUniqueId VARCHAR (32) NULL, version INTEGER NOT NULL, uniqueId VARCHAR (32) NOT NULL, name VARCHAR (40) NULL, PRIMARY KEY (uniqueId), FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId) ); but leave the uniqueness attribute in the mapping file: <many-to-one name="pass" class="application.business.logic.Passport" cascade="save-update,merge" unique="true" > <column name="PassUniqueId"/> </many-to-one> The resulting solution worked fine and I was able to create instances of Person not linked to a Passport. However Hibernate didn't succed in keeping the association from degrading into a many-to-one. It enabled me to create two Persons linked with the same Passport: PASSUNIQUEID | VIRSION | UNIQUEID | Name ================================================ 0d8b3919fffff | 1 | 0d5fb1dcfff | John 0d8b3919fffff | 0 | 10fd07bdfff | Sam A subsequent attempt at retrieving such Persons with Hibernate failed: org.hibernate.HibernateException: More than one row with the given identifier was found: 0d8b3919ffffffd60151e135b6da0164, for class: application.business.logic.Passport. Hibernate should be able to impose the single end property of such associations without relying on the underlying RDBMS engine and never allow them to degrade to many-to-ones. -- 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

[Hibernate-JIRA] Created: (HHH-2131) SYBASE +select for update is showing deadlock because lock is not working properly

by George Thomas (JIRA)

SYBASE +select for update is showing deadlock because lock is not working properly ---------------------------------------------------------------------------------- Key: HHH-2131 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2131 Project: Hibernate3 Type: Bug Components: core Versions: 3.1.3 Environment: sybaseASE 12.5.03 in solaris +hibernate3.1.3 Reporter: George Thomas I am connecting to Sybase database from hibernate.I tried setting locks using while selecting rows 1.session.load(class,id,LOCKMODE.UPGRADE) 2.session.lock(obj,LOCKMODE.UPGRADE) I am attaching a sample code while updating a field in table fund after selecting it. { Fund fund = null; ClientCredential credential = new ClientCredential("testDatabase", fund); org.hibernate.Session session = SessionFactoryManager.getSessionFactory(credential).getCurrentSession(); Transaction transaction = session.beginTransaction(); log.info("Run by " + Thread.currentThread().getName()); fund = (Fund) session.get(Fund.class, new Short((short)12), LockMode.UPGRADE); fund.setLegalEntityOrgId(fund.getLegalEntityOrgId()+1); transaction.commit(); } my requirement was that i wanted to do a select for update.I should acquire lock on certain rows and do a matching and if concurrent request comes ,it should wait till transaction is over that is lock is released. When I went through the hibernate code,the hibernate is making static queries in the beginning while loading session factory.Since we are appending the holdlock during execution,the sybase dialect is not appending.
