[Hibernate-JIRA] Created: (HHH-2088) TypeMismatchException on object equality expression from one-to-one relationship

by Salvatore Insalaco (JIRA)

TypeMismatchException on object equality expression from one-to-one relationship -------------------------------------------------------------------------------- Key: HHH-2088 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2088 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Reporter: Salvatore Insalaco Suppose to have entity A with a one-to-one constrained relationship to an entity B, called bRel. The query: "from A a, B b where a.bRel = b" raises a TypeMismatchException, even if bRel and b are instances of the same entity. This happens because in BinaryLogicOperatorNode: - lhsType is org.hibernate.type.Type = org.hibernate.type.OneToOneType(B)", with getColumnSpan returning 0. - rhsType is org.hibernate.type.Type = org.hibernate.type.ManyToOneType(B)", with getColumnSpan returning 1. And it compares the two columnspans. It doesn't happen with 3.2.0.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: call identity() Hibernate: insert into Child (id, name, parent_fk) values (null, ?, ?) Hibernate: call identity() Hibernate: select parent0_.id as id0_0_, parent0_.name as name0_0_ from Parent parent0_ where parent0_.id=?

Why is this exception thrown under these circumstances? Am I using the API in an undocumented/disallowed way? If yes, where exactly? The Hibernate API doc says, that Session.get() returns null if an object can't be found. No exception should be thrown. However, Session.get() at the end of sample code does return null as expected, if either a) Session.get() is used instead of load() some lines above (see commented line) b) the transaction and the session is isn't closed or reopened, respectively c) Session.flush() is called before the final call to Session.get() I'd like to understand why Hibernate behaves like this, which I presume is erroneous. I'm a beginner in Hibernate, but I couldn't get any help in the forum.

[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
