[Hibernate-JIRA] Created: (HHH-6661) Parent-child self-referencing relationship via link table causes QuerySyntaxException:(table) is not mapped when retrieving previous revisions

by Gerard Krupa (JIRA)

Parent-child self-referencing relationship via link table causes QuerySyntaxException:(table) is not mapped when retrieving previous revisions ---------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-6661 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6661 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.6.7 Environment: Hibernate 3.6.7.Final, Oracle 11g DB (also reproduced with Derby 10.8.1.2), Spring 3.0.3 Reporter: Gerard Krupa Attachments: gjkrupa_envers_problem.zip We have a parent-child relationship set up for an entity using a plain link table. This is annotated with @JoinTable and @AuditJoinTable so there is no entity for the link table itself. The definition looks something like this... @Entity @Table(name = "BKG_BKCM_BKG_CMPT") @Audited public class BookingComponent implements Serializable { @ManyToOne(fetch = FetchType.LAZY, optional = true) @AuditJoinTable(name = "BKG_BKCMR_REL_AUD", inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) }) @JoinTable(name = "BKG_BKCMR_REL", joinColumns = { @JoinColumn(name = "BKCM_ID_CHILD", nullable = true, updatable = false) }, inverseJoinColumns = { @JoinColumn(name = "BKCM_ID_PARENT", nullable = true, updatable = false) }) private BookingComponent parent; @OneToMany(mappedBy = "parent") private List<BookingComponent> children; } We've found two issues. Firstly, when we try to retrieve a previous revision of these entities (they in turn are held in a collection in a container entity) using List<>.size() Envers seems to be constructing a JPQL query using the link table's table name which isn't valid JPQL resulting in the following exception: org.hibernate.hql.ast.QuerySyntaxException: BKG_BKCMR_REL_AUD is not mapped [select new list(ee, e) from BKG_BKCMR_REL_AUD ee, *package-name-omitted*.BookingComponent_AUD e where ee.originalId.BookingComponent_id = e.originalId.id and ee.originalId.children_id = :children_id and e.originalId.rev_id.id <= :revision and ee.originalId.rev_id.id <= :revision and ee.rev_type != :delrevisiontype and e.rev_type != :delrevisiontype and (e.REV_ID_END.id > :revision or e.REV_ID_END is null) and (ee.REV_ID_END.id > :revision or ee.REV_ID_END is null)] at org.hibernate.hql.ast.util.SessionFactoryHelper.requireClassPersister(SessionFactoryHelper.java:180) at org.hibernate.hql.ast.tree.FromElementFactory.addFromElement(FromElementFactory.java:111) at org.hibernate.hql.ast.tree.FromClause.addFromElement(FromClause.java:93) at org.hibernate.hql.ast.HqlSqlWalker.createFromElement(HqlSqlWalker.java:327) at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromElement(HqlSqlBaseWalker.java:3441) at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromElementList(HqlSqlBaseWalker.java:3325) at org.hibernate.hql.antlr.HqlSqlBaseWalker.fromClause(HqlSqlBaseWalker.java:733) at org.hibernate.hql.antlr.HqlSqlBaseWalker.query(HqlSqlBaseWalker.java:584) at org.hibernate.hql.antlr.HqlSqlBaseWalker.selectStatement(HqlSqlBaseWalker.java:301) at org.hibernate.hql.antlr.HqlSqlBaseWalker.statement(HqlSqlBaseWalker.java:244) at org.hibernate.hql.ast.QueryTranslatorImpl.analyze(QueryTranslatorImpl.java:254) at org.hibernate.hql.ast.QueryTranslatorImpl.doCompile(QueryTranslatorImpl.java:185) at org.hibernate.hql.ast.QueryTranslatorImpl.compile(QueryTranslatorImpl.java:136) at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:101) at org.hibernate.engine.query.HQLQueryPlan.<init>(HQLQueryPlan.java:80) at org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:124) at org.hibernate.impl.AbstractSessionImpl.getHQLQueryPlan(AbstractSessionImpl.java:156) at org.hibernate.impl.AbstractSessionImpl.createQuery(AbstractSessionImpl.java:135) at org.hibernate.impl.SessionImpl.createQuery(SessionImpl.java:1770) at org.hibernate.envers.entities.mapper.relation.query.TwoEntityQueryGenerator.getQuery(TwoEntityQueryGenerator.java:128) at org.hibernate.envers.entities.mapper.relation.lazy.initializor.AbstractCollectionInitializor.initialize(AbstractCollectionInitializor.java:62) at org.hibernate.envers.entities.mapper.relation.lazy.proxy.CollectionProxy.checkInit(CollectionProxy.java:50) at org.hibernate.envers.entities.mapper.relation.lazy.proxy.CollectionProxy.size(CollectionProxy.java:55) We've also noticed that the audit entries for the link table have a null REV_ID_END despite there being multiple revisions. See attached gjkrupa_envers_problem.zip for a test case that demonstrates this issue. -- This message is automatically generated by JIRA.

[Hibernate-JIRA] Created: (HHH-4959) Concurrent HQL parsing blocks on ReflectHelper.classForName()

by Jarl Totland (JIRA)

Concurrent HQL parsing blocks on ReflectHelper.classForName() ------------------------------------------------------------- Key: HHH-4959 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4959 Project: Hibernate Core Issue Type: Improvement Components: query-hql Affects Versions: 3.3.2 Environment: DB2 Reporter: Jarl Totland Priority: Minor Attachments: ReflectHelper.java For particularly HQL-heavy applications, concurrency is lost as ReflectHelper.classForName() blithely runs loadClass() for tokens again and again, many of which are not even classes. As loadClass() is synchronized it end up blocking while it generates stacktraces for its exceptions. This goes for both classic and AST parsers. Because of this blocking our regression tests took over 20 minutes, regardless of number of threads. Implementing a simple cache from String to Class in ReflectHelper.classForName() reduced this to 3 minutes for eight threads on a dual-core cpu; the bottleneck is now the database as it should be, not lock contention. The issue was reported earlier in HHH-1810, but dismissed as related to the classic parser only. We might use HQL in inappropriate ways, but still wouldn't hurt for Hibernate to support this. Attached is our modified ReflectHelper; modified code is in the classForName()-methods, classForNameInternal(), and the static HashMap<String, Object> classes. -- 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-5274) HQL-Insert with Select and Sub-Select fails

by Björn Moritz (JIRA)

HQL-Insert with Select and Sub-Select fails ------------------------------------------- Key: HHH-5274 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5274 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.2 Environment: Hibernate 3.5.2, Oracle 10 (using org.hibernate.dialect.Oracle10gDialect) Reporter: Björn Moritz Attachments: Testcase.zip In Hibernate 3.5.2 a HQL-Insert statement doing a select using a subselect is failing. This is due to a wrong replacement of the table name in the generated SQL-Statement. The following statement will work: {code:sql}select a.id from A a where exists (select 1 from B b where b.id = a.id){code} but an insert statement embedding the same statement does not work: {code:sql}insert into C (id) select a.id from A a where exists (select 1 from B b where b.id = a.id){code} The latter statement will thrown an SqlSyntaxErrorException as the second 'a.id' will get replaced with 'AAA.id' (which is the real table name and not the alias used in the generated sql statement). In Hibernate 3.1.3 both statements worked fine. -- 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
