[Hibernate-JIRA] Created: (HHH-7285) Using distinct in Criteria, using first- and maxResults, fails with SQLGrammarException when a colum in the distinct clause starts with 'from'

by Markus Horehled (JIRA)

Using distinct in Criteria, using first- and maxResults, fails with SQLGrammarException when a colum in the distinct clause starts with 'from' ---------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-7285 URL: https://hibernate.onjira.com/browse/HHH-7285 Project: Hibernate ORM Issue Type: Bug Components: query-criteria Affects Versions: 3.6.9 Environment: Spring 3.1.1, Hibernate 3.6.9, SQL Server 2008 Reporter: Markus Horehled Using Hibernate Criteria with setting first- and maxResults fails with an SQLGrammarException in SQLServer 2008 when one of the columns in the select distinct clause starts with a 'from', like fromDate. The original query would be something like: select distinct this_.Id as y0_, this_.FromDate as y1_ from ... whereas the query eventually issued by Hibernate is something like: WITH query AS (select ROW_NUMBER() OVER (order by this_.fromdate desc, this_.id asc) ... group by this_.id, this_.) SELECT * FROM query WHERE __hibernate_row_nr__ BETWEEN ? AND ? The fromDate column is apparently missing in the query's group by. Reason is found in the SQLServer2005Dialect class in getSelectFieldsWithoutAliases(StringBuilder sql), where a substring is constructed till the FROM (i.e. 'from') string. This should rather be 'from ', i.e. including a blank, since in that particular case the 'from' from the 'fromDate' column is being regarded as the end of the substring being constructed. Workaround is for example to not name any column being used in a distinct starting with 'from' -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-3961) SQLServerDialect, support nowait in LockMode.UPGRADE_NOWAIT

by Guenther Demetz (JIRA)

SQLServerDialect, support nowait in LockMode.UPGRADE_NOWAIT ------------------------------------------------------------ Key: HHH-3961 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3961 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.3.1 Environment: 3.3.1 GA , SQLServer2008 Reporter: Guenther Demetz Priority: Trivial The method SQLServerDialect#appendLockHint currently ignores the LockMode.UPGRADE_NOWAIT returning the same string as for LockMode.UPGRADE. public String appendLockHint(LockMode mode, String tableName) { if ( mode.greaterThan( LockMode.READ ) ) { // does this need holdlock also? : return tableName + " with (updlock, rowlock, holdlock)"; return tableName + " with (updlock, rowlock)"; } else { return tableName; } } As SQLServer supports the nowait option I propose the following improvement: public String appendLockHint(LockMode mode, String tableName) { if ( mode == LockMode.UPGRADE_NOWAIT) { return tableName + " with (updlock, rowlock, nowait)"; } else if ( mode.greaterThan( LockMode.READ ) ) { // does this need holdlock also? : return tableName + " with (updlock, rowlock, holdlock)"; return tableName + " with (updlock, rowlock)"; } else { return tableName; } } A test gave me a correct behaviour: if the concerning row is already locked, then after Lock request time out period exceeded following exception is thrown: org.hibernate.exception.SQLGrammarException: could not lock: [persistent.jpa.AssociationsClassPeer#1] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:90) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) at org.hibernate.dialect.lock.SelectLockingStrategy.lock(SelectLockingStrategy.java:115) at org.hibernate.persister.entity.AbstractEntityPersister.lock(AbstractEntityPersister.java:1361) at org.hibernate.event.def.AbstractLockUpgradeEventListener.upgradeLock(AbstractLockUpgradeEventListener.java:108) at org.hibernate.event.def.DefaultLockEventListener.onLock(DefaultLockEventListener.java:87) at org.hibernate.impl.SessionImpl.fireLock(SessionImpl.java:611) at org.hibernate.impl.SessionImpl.lock(SessionImpl.java:603) ...

[Hibernate-JIRA] Created: (HHH-7299) Cannot scroll ScrollableResults outside of a transaction

by Ittay Dror (JIRA)

Cannot scroll ScrollableResults outside of a transaction -------------------------------------------------------- Key: HHH-7299 URL: https://hibernate.onjira.com/browse/HHH-7299 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.2 Reporter: Ittay Dror I have a repository class who is transactional but used by other classes that are not. One of its methods returns a ScrollableResults object. In 3.6.9 I was able to work with it (outside of the transaction), but in 4.1.2 I get an exception. Why should scrolling a query require a transaction? org.hibernate.HibernateException: proxy handle is no longer valid at org.hibernate.engine.jdbc.internal.proxy.AbstractProxyHandler.errorIfInvalid(AbstractProxyHandler.java:63) ~[hibernate-core-4.1.2.jar:4.1.2] at org.hibernate.engine.jdbc.internal.proxy.AbstractResultSetProxyHandler.continueInvocation(AbstractResultSetProxyHandler.java:84) ~[hibernate-core-4.1.2.jar:4.1.2] at org.hibernate.engine.jdbc.internal.proxy.AbstractProxyHandler.invoke(AbstractProxyHandler.java:81) ~[hibernate-core-4.1.2.jar:4.1.2] at $Proxy99.next(Unknown Source) ~[na:na] at org.hibernate.internal.ScrollableResultsImpl.next(ScrollableResultsImpl.java:116) ~[hibernate-core-4.1.2.jar:4.1.2] at com.alu.dal.util.HibernateScrollableIterator.advance(HibernateScrollableIterator.java:64) ~[classes/:na] at com.alu.dal.util.HibernateScrollableIterator.hasNext(HibernateScrollableIterator.java:41) ~[classes/:na] -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-7151) Like the query-API, also NaturalIdLoadAccess should provide method setFlushMode(FlushMode mode)

by Guenther Demetz (JIRA)

Like the query-API, also NaturalIdLoadAccess should provide method setFlushMode(FlushMode mode) ----------------------------------------------------------------------------------------------- Key: HHH-7151 URL: https://hibernate.onjira.com/browse/HHH-7151 Project: Hibernate ORM Issue Type: Improvement Components: core Affects Versions: 4.1.1 Environment: - Reporter: Guenther Demetz Implicit flushes in my opinion always should be, as widest as possible, under users control, this because unneccessary flushings often create serious implications, especially when working with long-time transactions. On long-time transactions the time-window between flush and final commit become big enough to cause lock-waits or/and lock-timeouts on concurrent transactions. With bugfix HHH-7094 the NaturalIdLoadAccess becomes pratically ununseable for our projects. Like on all Hibernate Query-Apis, the user should have the possibility to choose between variuos FlushModes. Example: (Simple)NaturalIdLoadAccess naturalIdAccess = session.by(Simple)NaturalId(MyEntity.class); naturalIdAccess.setFlushMode(FlushMode.AUTO); // flush if required naturalIdAccess.setFlushMode(FlushMode.COMMIT); // don't flush until commit time Object obj = naturalIdAccess.load(id); N.B.: I enabled the 'Requires Release Note' check-box, because this enhancement implies a behaviour change. -- This message is automatically generated by JIRA.
