[Hibernate-JIRA] Created: (HHH-3011) merge() optimization for Oracle dialect

by MG (JIRA)

merge() optimization for Oracle dialect --------------------------------------- Key: HHH-3011 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3011 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: MG Priority: Minor merge() optimization for Oracle dialect. Since 9i Oracle has a MERGE statement which is very useful to save round trips to database in merge() call which will make dramatic improvement for performance of loading large row sets. MERGE command processes the conditional INSERT-or-UPDATE within a single statement. So instead of doing 'select' first to detect whether entity is in database or not (This is one round trip to DB) and then issuing 'update' or 'insert' all of it could be done in one statement with no extra round trips using oracle SQL MERGE statement. http://www.oracle.com/technology/products/oracle9i/daily/Aug24.html -- 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-3317) Entities saved within onPreUpdate() never inserted into db when id generator is sequenze (f.e. oracle)

by Martin Backhaus (JIRA)

Entities saved within onPreUpdate() never inserted into db when id generator is sequenze (f.e. oracle) ------------------------------------------------------------------------------------------------------ Key: HHH-3317 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3317 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.6 Environment: hibernate3.2.6.ga.jar, Oracle 10 Reporter: Martin Backhaus Priority: Minor If you save (insert) a entity within the event preUpdate and the id is a oracle-sequenze, hibernate put the entity to insert in the session-ActionQueue, BUT NEVER INSERTS it. If you use mysql/hsql... where the id is differently generated, the insert happens immediately and no put to the ActionQueue occures. As workaround you can queue the object (to insert) yourself and call save() within the postUpdate-Event. I use this events for historizing some stuff. Inserts within onDelete() works fine. the ids are annotated as shown here: @Id @GeneratedValue(strategy = GenerationType.AUTO) protected Long id = null; -- 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-2657) Bulk select using primary key or natural id

by charbel (JIRA)

Bulk select using primary key or natural id ------------------------------------------- Key: HHH-2657 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2657 Project: Hibernate3 Issue Type: Improvement Reporter: charbel I think that the following methods are really useful once we use hibernate with huge datas in the database: Object[] get(Class,Object[] id): ---------------------------------------- return objects giving their primary key. First check in cache if it exists, if not either use a select in () either create a temporary table if too many ids. Object[] getUsingNaturalId(Class,Object[] id): ---------------------------------------- return objects giving their natural id. the same thing than before. Be careful on the fact that the primary key and the naturalid can be composite objects. -- 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-2331) bulk deletes on ID must not use HT_ tables

by Amir Pashazadeh (JIRA)

bulk deletes on ID must not use HT_ tables ------------------------------------------ Key: HHH-2331 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2331 Project: Hibernate3 Type: Improvement Components: core Reporter: Amir Pashazadeh when using bulk deletes hibernate inserts ids of rows which must be deleted in a temporary table (with HT_ prefix); I believe that's just for knowing primary keys of objects which must be deleted and updating caches. so if that is the reason there is no need to do so when deleting on primary key property, (for example "delete from MyEntity where id = ?") -- 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
