Adding a new ResultTransformer, permitting to instantiate and fill related beans and not to take care of aliases case. ---------------------------------------------------------------------------------------------------------------------- Key: HHH-2288 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2288 Project: Hibernate3 Type: Improvement Components: query-sql, query-hql, query-criteria Versions: 3.2.1 Environment: Developped based on hibernate v 3.2.1 Reporter: Nicolas Billard Priority: Minor Attachments: ResultTransformerImprovement.zip Are joined to this post 2 classes.

[Hibernate-JIRA] Created: (HHH-2501) Read-only state of an entity in a session to propagate into subsequently lazy-loaded entities.

by Gunther Schadow (JIRA)

Read-only state of an entity in a session to propagate into subsequently lazy-loaded entities. ---------------------------------------------------------------------------------------------- Key: HHH-2501 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2501 Project: Hibernate3 Type: Improvement Components: core Environment: any Reporter: Gunther Schadow ISSUE: Given an Entity entity and after Session.setReadOnly(entity), if the entity has lazy collections, lazy properties etc., other Entities are loaded into the Session upon navigating the object graph in the default read-writable state. However, it seems more reasonable to maintain the read-only state of the owning object. REQUEST: Ability to propagate read-only state of an entity in a session into other lazy-loaded entities. BACKGROUND: We have a system which permits users to make concurrent transactions which involve many of the same objects. Usually no changes happen on these shared objects, but instead connections (links) are made between these objects and new objects. For example, say you have an online meeting system, and every Meeting held has a link to a number of User object. The User objects are never changed in a Meeting, but there is a Relation called Participation (of User in Meeting) to which new relationships are added. When a new meeting is saved, it wants to save the User objects simply because a new Participation link entry was added to the collection. To an extent we can prevent this from happening by setting the Users explicitly to read-only. However, now suppose we added a function "Invite your Friends" to a Meeting, in which we would simply go: for(User friend : currentUser.getFriends()) meeting.addInvitation(friend); Now an Invitation is like a Participation, and would be added into the User but now it wants to save these users just for a version upgrade only because they have received an Invitation. -- 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-2094) Hibernate is ignoring native sql aliases and generating "column not found" error

by Leonardo Penczek (JIRA)

Hibernate is ignoring native sql aliases and generating "column not found" error -------------------------------------------------------------------------------- Key: HHH-2094 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2094 Project: Hibernate3 Type: Bug Components: query-sql Versions: 3.2.0.cr4 Environment: 3.2.0.cr4, Adaptive Server Enterprise/12.5.3 Reporter: Leonardo Penczek Priority: Critical As simples as that: 1: Query q = em.createNativeQuery("select cd_person as codePerson, cd_person as identif from PERSON"); 2: List<Object[]> resultList = (List<Object[]>) q.getResultList(); Hibernate is ignoring my aliases when retrieving information from the ResultSet because it is trying to retrieve by column name, generating the following error: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:641) at org.hibernate.ejb.QueryImpl.getResultList(QueryImpl.java:73) at <my line 2 in the code above> ...

The SQL query runs, but the Hibernate try to get the column by the original name, not by the alias, causing the error! It is not possible to correctly get the value of 2 different columns that have the same name!!!! Hint: why Hibernate use ResultSet.get* by column name instead of positional ResultSet.get* (1, 2, 3,...)? It will solve this problem. -- 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-2676) Cannot apply UPGRADE lock to scalar Query object

by John Wood (JIRA)

Cannot apply UPGRADE lock to scalar Query object ------------------------------------------------ Key: HHH-2676 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2676 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.1 Reporter: John Wood Priority: Minor Attachments: Bean.hbm.xml, Bean.java If you try and add a lock to a Query object (against a named alias) when doing a scalar HQL query (e.g. "select sum(foo) from bah") then an error occurs. The sample code (full working example is attached): // Create query Query q = session.createQuery("select b.value from Bean b"); // Set lock mode on query q.setLockMode("b", LockMode.UPGRADE); // Executre q.list(); This causes the following error: Exception in thread "main" java.lang.IllegalArgumentException: could not locate alias to apply lock mode : b at org.hibernate.loader.hql.QueryLoader.applyLocks(QueryLoader.java:297) at org.hibernate.loader.Loader.preprocessSQL(Loader.java:201) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1538) at org.hibernate.loader.Loader.doQuery(Loader.java:673) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:236) at org.hibernate.loader.Loader.doList(Loader.java:2220) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2104) at org.hibernate.loader.Loader.list(Loader.java:2099) at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:378) at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:338) at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:172) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1121) at org.hibernate.impl.QueryImpl.list(QueryImpl.java:79) I have tried this both with an older version of Hibernate (3.1) and the latest with the same result (although the older Hibernate has the error message "alias not found". I have attached a simple example to demonstrate this. See also HHH-1965. Perhaps, it is simply that one cannot lock scalar queries of this type. If so, then the fix would presumably be to include this in the Query class Javadocs. -- 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-2146) NullpointerException in DefaultDeleteEventListener.deleteTransientEntity

by Martin Kartumovich (JIRA)

NullpointerException in DefaultDeleteEventListener.deleteTransientEntity ------------------------------------------------------------------------ Key: HHH-2146 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2146 Project: Hibernate3 Type: Bug Versions: 3.2.0.cr5 Environment: Hibernate 3.2.0cr5, Oracle10g Reporter: Martin Kartumovich Priority: Blocker The following setup leads to a NPE in DefaultDeleteEventListener.deleteTransientEntity: Tables A, B Table V_A_B that is an M-N-Connection between A and B. Pojo for A has a Set of V_A_Bs. Pojo for B has a Set of V_A_Bs. Pojo C that has Sets of As and Bs. Cascades: all, delete-orphan -Create a new A and add a new V_A_B to its Set, that references to an existing B. -Delete B. -SaveOrUpdate Pojo C. In Hibernate 3.1.3 this works fine. In 3.2.0cr4+cr5 the removal of B results into an cascading removal of the never persisted V_A_B in the Set of B instead of ignoring it. This leads to an incorrect state where deleteTransientEntity is called with transientEnties=null. When now calling transientEnties.contains(...) the NPE is thrown. -- 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
