[Hibernate-JIRA] Created: (ANN-592) @TableGenerator realisation does not respect initialValue

by Christoph Schönfeld (JIRA)

@TableGenerator realisation does not respect initialValue --------------------------------------------------------- Key: ANN-592 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-592 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.0.ga Reporter: Christoph Schönfeld Priority: Minor I would like to have generated IDs for a certain entity type start at the value of 1000. Consider the following example. @TableGenerator(name = "employee", table = "SEQUENCES", pkColumnName = "name", valueColumnName = "value", pkColumnValue = "employee", allocationSize = 10, initialValue = 1000) Hibernate generates the SEQUENCES table correctly but it always returns 1 as the first generated key. In the source code of AnnotationBinder.java which seems to be responsible for binding the @TableGenerator annotation to a MultipleHiLoPerTableGenerator instance the initialValue property is ignored. -- 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-3018) Configuration element to tell Hibernate to have just one insert to flush an entity and not both an insert and an update.

by Nicolas Cazottes (JIRA)

Configuration element to tell Hibernate to have just one insert to flush an entity and not both an insert and an update. ------------------------------------------------------------------------------------------------------------------------ Key: HHH-3018 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3018 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.5 Reporter: Nicolas Cazottes Attachments: testXMLTypeUpdates.zip While analyzing the SQL queries Hibernate generates to persist objects, I fall on a behaviour, that I first found strange, which is that in one flush of one transaction, there may be both an insert and an update for a given entity. My first expectation was to have only one insert and no update. After a few search, I discover that conversation (http://forum.hibernate.org/viewtopic.php?p=2191664&sid=c571096bda4a6b636e...) that explains it is normal in the case of a save with modifications after save. I discover (cf the classes of my zip showing it) that this behaviour is also present in the case of a relation that is managed by cascade. What I noticed is that the insert of the related entity is planned when the first hql query is executed after the relation has been established. So if the related entity is modified after the query execution (for exemple depending on the result of the query), an update will be executed. This behaviour is understandable but in my case, the update is really expensive (because it acts on an XMLType column) and unless I set a FlushMode to COMMIT (which I found really not a good solution), I can not control that Hibernate will generate both an insert and an update or only an insert. I know I could also set the relation just before the commit in order to avoid insert+update but this solution is not possible in my case and I find it not elegant (it would break the semantic of the cascade of the relation). I suggest to introduce a new configuration element (similar to the flushmode) in Hibernate in order to be able to have control whether Hibernate generates an insert containing the data of the entity at the first save or an insert containing the data of the entity at the flushing time. Note : The attached files (which is the smallest extraction of what does my application) shows that behaviour both for the save call and the cascade declenched by a query. Note2 : I found an issue in jira number 2621 submited by someone else that is related to this subject in think. -- 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: (ANN-682) @ForeignKey override of @MappedSuperclass

by Christian Bauer (JIRA)

@ForeignKey override of @MappedSuperclass ----------------------------------------- Key: ANN-682 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-682 Project: Hibernate Annotations Issue Type: New Feature Components: binder Reporter: Christian Bauer Put this @ManyToOne in a @MappedSuperclass: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "CREATED_BY_USER_ID", nullable = false) // Ideally this foreign key should be ON DELETE SET NULL, however... // Hibernate can't rename these so subclasses would get the same FK constraint name. This doesn't // work, so we need to let Hibernate create a random identifier for these. We could fix this in the // DatabaseObjects.hbm.xml file but we can't even address it because the name is random. This sucks. // So we do a manual SET NULL|DEFAULT when userHome.remove() is called. // @org.hibernate.annotations.ForeignKey(name = "FK_WIKI_NODE_CREATED_BY_USER_ID") protected User createdBy; Now all subclasses get that foreign key constraint name in the database catalog, which isn't possible - constraint names have to be unique. -- 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-3976) NPE when eager fetching joined component with native SQL query

by Franz Allan Valencia See (JIRA)

NPE when eager fetching joined component with native SQL query -------------------------------------------------------------- Key: HHH-3976 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3976 Project: Hibernate Core Issue Type: Bug Components: query-sql Affects Versions: 3.2.0.ga Reporter: Franz Allan Valencia See Priority: Critical Given a Hibernate Mapping with formula and named sql query, When accessing named sql query, NPE is thrown. This is basically a duplicae of HHH-2225. But since I cannot edit that to change it's Priority, I created a dupe. Feel free to close this if HHH-2225 has been edited to a higher priority. IMHO, it should be of a higher priority because AFAIK there are no decent workaround for this. -- 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-3339) Query cache stops working after object save

by Alex Oleynikov (JIRA)

Query cache stops working after object save ------------------------------------------- Key: HHH-3339 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3339 Project: Hibernate3 Issue Type: Bug Components: caching (L2) Affects Versions: 3.2.6 Environment: Hibernate 3.2.6, MS SQL 2005 Database. Windows XP SP2 Reporter: Alex Oleynikov It seems like HB Query cache stops working as soon as given object type is being saved (it does not matter if it was save to existing object or insert of new object instance). The code looks like this. Where User is just a primitive POJO with couple of properties. // #1 query = session.createQuery("from User where userID = :id"); query.setCacheable(true); query.setParameter("id", 10); user = (User) query.list().get(0); // #2 query = session.createQuery("from User where userID = :id"); query.setCacheable(true); query.setParameter("id", 10); user = (User) query.list().get(0); // insert new User object user = new User(); user.setUserID((int)(Math.random() * Integer.MAX_VALUE)); user.setUserName("Ten"); session.beginTransaction(); session.save(user); session.getTransaction().commit(); // #3 query = session.createQuery("from User where userID = :id"); query.setCacheable(true); query.setParameter("id", 10); user = (User) query.list().get(0); // #4 query = session.createQuery("from User where userID = :id"); query.setCacheable(true); query.setParameter("id", 10); user = (User) query.list().get(0); >From MS SQL Profiler I can clearly see that no queries is executed for #2 (e.g. it hit the cache), but queries are executed for #3 and #4. From HB debug log I see following: For #2 Query (cache is hit) - correct: 06:54:25,337 DEBUG StandardQueryCache:102 - checking cached query results in region: org.hibernate.cache.StandardQueryCache 06:54:25,337 DEBUG StandardQueryCache:156 - Checking query spaces for up-to-dateness: [USERS] 06:54:25,337 DEBUG StandardQueryCache:117 - returning cached query results During User insert: 06:54:25,368 DEBUG UpdateTimestampsCache:65 - Invalidating space [USERS], timestamp: 4967466866147328 For #3 Query: 06:54:25,368 DEBUG StandardQueryCache:156 - Checking query spaces for up-to-dateness: [USERS] 06:54:25,368 DEBUG UpdateTimestampsCache:86 - [USERS] last update timestamp: 4967466866147328, result set timestamp: 4967466865061888 06:54:25,368 DEBUG StandardQueryCache:113 - cached query results were not up to date For #4 Query (or any subsequent query for this matter): 06:54:25,368 DEBUG StandardQueryCache:156 - Checking query spaces for up-to-dateness: [USERS] 06:54:25,368 DEBUG UpdateTimestampsCache:86 - [USERS] last update timestamp: 4967466866147328, result set timestamp: 4967466865061888 06:54:25,368 DEBUG StandardQueryCache:113 - cached query results were not up to date Please note the timestamp numbers for #4 query - even though I would expect query to be re-cached in #3, it still shows old timestamp.

[Hibernate-JIRA] Created: (HHH-3407) @TableGenerator does not increment pkColumnValue by allocationSize

by Dan Ciarniello (JIRA)

@TableGenerator does not increment pkColumnValue by allocationSize ------------------------------------------------------------------ Key: HHH-3407 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3407 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6, 3.2.4 Environment: JBoss 4.2.3, RHEL4, JDK1.5 Reporter: Dan Ciarniello According to the JPA, the allocationSize attribute to @TableGenerator is "The amount to increment by when allocating id numbers from the generator" but the value is actually incremented by 1 regardless of allocationSize. The id is generated properly apparently according to the formula id = lastkeyval*allocationSize + i where 0<i<allocationSize The problems with this algorithm are: 1. One cannot tell what the next key value range is from the key table without knowing the allocationSize (minor) 2. If the allocationSize is reduced, already existing key values will be generated (major) 3. If two applications are configured with different allocation sizes, there will be an overlap in generated values (major) -- 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-3709) Add StartRevision/EndRevison fileds to audit tables

by jason shi (JIRA)

Add StartRevision/EndRevison fileds to audit tables --------------------------------------------------- Key: HHH-3709 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3709 Project: Hibernate Core Issue Type: Improvement Components: envers Affects Versions: 3.4 Reporter: jason shi In Envers audit tables(eg:Person_Aud), two fields added:REV,REVTYPE When retrieve data at special REV, a sql with subselect executed: select a.id, a.REV, a.REVTYPE, a.name, a.surname, a.address_id from Person_AUD a where a.REVTYPE <> ? and a.id = ? and a.REV = (select max(b.REV) from Person_AUD b where b.REV <= ? and a.id = b.id) The sql performance is poor. I suggest adding StartRevision/EndRevison fileds to the audit tables,replace the REV field. The StartRevision equals the original REV field,EndRevision will be filledd when this record changed in next Revision. The new query sql will like this: select a.id, a.REV, a.REVTYPE, a.name, a.surname, a.address_id from Person_AUD a where a.REVTYPE <> ? and a.id = ? and a.StartRevision<=? and a.EndRevision>? -- 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
