[Hibernate-JIRA] Created: (EJB-376) EntityManager.createQuery does not recognize COUNT CASE statement

by Mark Plutowski (JIRA)

EntityManager.createQuery does not recognize COUNT CASE statement ----------------------------------------------------------------- Key: EJB-376 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-376 Project: Hibernate Entity Manager Issue Type: Bug Components: EntityManager Affects Versions: 3.4.0.CR2, 3.3.1.GA Environment: Tested with both Hibernate 3.2.5.ga and Hibernate 3.3.0.CR2, Postgres 8.1, Postgres 8.2, Linux Ubuntu. Reporter: Mark Plutowski I searched the Hibernate forums and did not find mention of this issue or one that was closely related. I also posted this to the Hibernate Users forum, and did not receive any replies recognizing the bug or stating that it has been resolved or has a workaround. To summarize, EntityManager.createQuery does not recognize SQL related to applying a COUNT to a CASE, whereas it does correctly run SQL that applies a SUM to a CASE. More detail follows. --- Summary Overview --- EntityManager.createQuery runs a SELECT query containing the following HQL/JQL snippet runs correctly: " SUM ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN 1 ELSE 0 END ) " However, the following do not work: " COUNT ( DISTINCT CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) " " COUNT ( DISTINCT (CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) ) " " COUNT ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) " The first two statements run and return correct results when translated to SQL and run against the Postgresql database in PgAdmin. Here's the exception thrown when using COUNT ( DISTINCT CASE WHEN 101976 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: CASE 101977 [main] ERROR org.hibernate.hql.PARSER - line 1:98: unexpected token: WHEN Here's the exception thrown when the extra parenthesis is added to give COUNT ( DISTINCT (CASE WHEN 85587 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: ( 85588 [main] ERROR org.hibernate.hql.PARSER - line 1:99: unexpected token: WHEN --- Additional Detail --- Here is the complete SQL for the COUNT (DISTINCT (CASE use case: String queryString = "Select c.id.pubId, c.id.clipId, c.duration, " + "count(distinct s.slotId) , " + " COUNT ( DISTINCT (CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN cs.componentId ELSE NULL END ) ) " + "from CmClip c " + "join c.cmClipSlots s " + "left outer join c.csComponents cs " + "where (s.adSizeX * c.width) >= :adWidth " + "and (s.adSizeY * c.height) >= :adHeight " + "and (c.isQaDone = true or c.isQaDone is null) " + "and c.isEnabled = true " + "group by c.id.pubId, c.id.clipId, c.duration " + "order by " + orderByCol; This results in the following exception: 85587 [main] ERROR org.hibernate.hql.PARSER - line 1:93: unexpected token: ( 85588 [main] ERROR org.hibernate.hql.PARSER - line 1:99: unexpected token: WHEN Here is the SQL for the SUM CASE sql snippet that does run and return correct results: String queryString = "Select c.id.pubId, c.id.clipId, c.duration, " + "count(distinct s.slotId) , " + " SUM ( CASE WHEN (cs.serveTs BETWEEN :beginTs AND :endTs ) THEN 1 ELSE 0 END ) " + "from CmClip c " + "join c.cmClipSlots s " + "left outer join c.csComponents cs " + "where (s.adSizeX * c.width) >= :adWidth " + "and (s.adSizeY * c.height) >= :adHeight " + "and (c.isQaDone = true or c.isQaDone is null) " + "and c.isEnabled = true " + "group by c.id.pubId, c.id.clipId, c.duration " + "order by " + orderByCol; Here is the code snippet that performs the transaction: float roFactor = (float) 0.5; transactionMgr.begin(); List<Object[]> result = entityMgr.createQuery(queryString) .setParameter("adWidth", (widthF-roFactor)). setParameter("adHeight", (heightF-roFactor)) .setParameter("beginTs", beginTs, javax.persistence.TemporalType.TIMESTAMP) .setParameter("endTs", endTs, javax.persistence.TemporalType.TIMESTAMP) .getResultList(); transactionMgr.commit(); The fact that "SUM (CASE" is parsed and run correctly, whereas "COUNT (CASE" throws an exception seems to indicate a bug. I replicated this using both (Hibernate 3.2.5.ga with EntityManager 3.3.1.GA) and (Hibernate 3.3.0.CR2 with EntityManager 3.4.0.CR2). -- 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-5845) Lazy Loading of audited entites with revision type 'delete'

by Jonas Schlaak (JIRA)

Lazy Loading of audited entites with revision type 'delete' ----------------------------------------------------------- Key: HHH-5845 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5845 Project: Hibernate Core Issue Type: Bug Components: envers Affects Versions: 3.5.6 Environment: Hibernate 3.5.6, Oracle 10 DB Reporter: Jonas Schlaak Two classes are given, and they are related via a OneToOne relationship: @Audited public class MyClass { @OneToOne @Cascade(value = CascadeType.ALL) private MyOtherClass otherClass; } @Audited public class MyOtherClass { } The property "org.hibernate.envers.store_data_at_delete" is set to true, and when auditquerying for the deleted objects and initiliazing the otherClass (an entity which is also deleted) property, and ObjectNotFoundExceptions is thrown. It seems that the proxies do not look for deleted entities, because the same query works fine for the entities of revision type 'ADD' and 'MOD'. The code of the query: AuditQuery queryDeleted = reader.createQuery().forRevisionsOfEntity( MyClass.class, false, true).add( AuditEntity.revisionType().eq(RevisionType.DEL)); List queryResult = queryDeleted.getResultList(); List<MyClass> result = new ArrayList<MyClass>(); for (Object object : queryResult) { Object[] oArray = (Object[]) object; MyClass c = (MyClass) oArray[0]; Hibernate.initialize(c.getOtherClass()); } Forum post with Adam Warski's response: http://community.jboss.org/thread/160939?tstart=0 -- 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-2951) Restrictions.eq when passed null, should create a NullRestriction

by David Sheldon (JIRA)

Restrictions.eq when passed null, should create a NullRestriction ----------------------------------------------------------------- Key: HHH-2951 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2951 Project: Hibernate3 Issue Type: Improvement Components: query-criteria Affects Versions: 3.2.1 Reporter: David Sheldon Priority: Trivial If you create a Restriction using eq, and pass null to it, then the generated SQL is "where foo = null", which always returns false. The programmer will almost certainly have intended to get "where foo is null". Ideally, we could change: public static SimpleExpression eq(String propertyName, Object value) { return new SimpleExpression(propertyName, value, "="); } to public static SimpleExpression eq(String propertyName, Object value) { if (value == null) { return isNull(propertyName); } else { return new SimpleExpression(propertyName, value, "="); } } Unforunately that wont work, as isNull doesn't return a SimpleExpression. -- 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
