[Hibernate-JIRA] Created: (HHH-5523) Inconsistence between handling of equality ops and LIKE

by Daniel Migowski (JIRA)

Inconsistence between handling of equality ops and LIKE ------------------------------------------------------- Key: HHH-5523 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5523 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: Hibernate Core 3.3.1, PostgreSQL 8.3 Reporter: Daniel Migowski These two queries should both be handled, but only the one with the ">" is correctly understood by the HQL Parser, the other fails. WORKS: SELECT a.id, a.name, a.articleGroup FROM Article a WHERE a.articleGroup.hierarchy > (SELECT ag2.hierarchy FROM ArticleGroup ag2 WHERE ag2.id=32) FAILS: SELECT a.id, a.name, a.articleGroup FROM Article a WHERE a.articleGroup.hierarchy LIKE (SELECT ag2.hierarchy FROM ArticleGroup ag2 WHERE ag2.id=32) About the Entities: Article has a ManyToOne relation to ArticleGroup, and articleGroup has a hierarchy String attribute, which helps us get some stuff done. I checked the SVN, and since http://anonsvn.jboss.org/repos/hibernate/core/tags/hibernate-3.5.5-Final/... is nearly the same as mine in v3.3.1 this should be reproducable in the current final version. -- 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. As a work around I tested with native sql with holdlock but when I test concurrent request using threads its bombing.Its throwing LockAcquisitionException.( Your server command (family id #0, process id #3777) encountered a deadlock situation.).can anyone give a solution to this problem??? org.hibernate.exception.LockAcquisitionException: could not update: [com.citco.aexeo.common.dataaccess.domain.Fund#12] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:84) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2223) at org.hibernate.persister.entity.AbstractEntityPersister.updateOrInsert(AbstractEntityPersister.java:2118) at org.hibernate.persister.entity.AbstractEntityPersister.update(AbstractEntityPersister.java:2375) at org.hibernate.action.EntityUpdateAction.execute(EntityUpdateAction.java:91) at org.hibernate.engine.ActionQueue.execute(ActionQueue.java:250) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:233) at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:140) at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:297) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:27) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:985) at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:333) at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:107) at com.satyam.Testing.doTransaction(Testing.java:103) at com.satyam.MyRunnable.run(MyRunnable.java:13) at java.lang.Thread.run(Thread.java:568) Caused by: com.sybase.jdbc2.jdbc.SybSQLException: Your server command (family id #0, process id #3777) encountered a deadlock situation.

[Hibernate-JIRA] Commented: (HHH-892) HQL parser does not resolve alias in ORDER BY clause

by Gail Badner (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-892?page=co... ] Gail Badner commented on HHH-892: --------------------------------- There is a problem with the patch. If there is an alias that has the same name as a column, the column takes precedence. This will happen, even if the column has a different alias. For example, an HQL query like: "select z.address as name, z.name as address from Zoo z order by name, address" is resolving to: <code> select zoo0_.street as col_0_0_, zoo0_.city as col_0_1_, zoo0_.postalCode as col_0_2_, zoo0_.country as col_0_3_, zoo0_.state_prov_id as col_0_4_, zoo0_.name as col_1_0_ from Zoo zoo0_ order by zoo0_.name, zoo0_.street, zoo0_.city, zoo0_.postalCode, zoo0_.country, zoo0_.state_prov_id </code> It should resolve to: <code> select zoo0_.street as col_0_0_, zoo0_.city as col_0_1_, zoo0_.postalCode as col_0_2_, zoo0_.country as col_0_3_, zoo0_.state_prov_id as col_0_4_, zoo0_.name as col_1_0_ from Zoo zoo0_ order by col_0_0_, col_0_1_, col_0_2_, col_0_3_, col_0_4_, col_1_0_ </code> > HQL parser does not resolve alias in ORDER BY clause > ----------------------------------------------------- > > Key: HHH-892 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-892 > Project: Hibernate Core > Issue Type: Bug > Components: query-hql > Affects Versions: 3.5.4, 3.6.0.Beta1 > Environment: Hibernate 3.0.5, MySQL, Tomcat > Reporter: Guido Laures > Assignee: Gail Badner > Fix For: 3.6.0.CR1 > > Attachments: HHH-892.patch, HibernateHavingAliasTest.java > > > When using an alias for an ORDER BY clause this is not always correctly resolved.
