[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] Créée: (HHH-2086) Patch for bug HHH-2076 and to be able to use <formula> in <key> for <one-to-many>

by Xavier Brénuchon (JIRA)

Patch for bug HHH-2076 and to be able to use <formula> in <key> for <one-to-many> --------------------------------------------------------------------------------- Key: HHH-2086 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2086 Project: Hibernate3 Type: Patch Components: core Versions: 3.2.0.cr4 Reporter: Xavier Brénuchon Attachments: formula_one_to_many.patch Hello, There is a patch to correct bug HHH-2076 and make an improvement for HHH-944. In fact, theses 2 cases are linked. They need, amongst other things, a formula in the right part of outer join. This patch is simple but many class concerns (to propagate formula templates). About formula in one-to-many : You must have at least a column (not only formula), because it's not possible to have an Update order without at least a column. If it is the case, hibernate patch will raise an MappingException rightly. This patch add two TestCase : org.hibernate.test.onetoone.bidirectionnalformula. OneToOneBidirectionalFormulaTest org.hibernate.test.onetomany.formula. OneToManyFormulaTest Would it be possible to integrate this patch into Hibernate 3.2 ? -- 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-2112) ClassCastException in StatefulPersistenceContext.getCachedDatabaseSnapshot(...)

by Aleksei Valikov (JIRA)

ClassCastException in StatefulPersistenceContext.getCachedDatabaseSnapshot(...) ------------------------------------------------------------------------------- Key: HHH-2112 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2112 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr4 Reporter: Aleksei Valikov StatefulPersistenceContext.getCachedDatabaseSnapshot(EntityKey key) causes ClassCastException when NO_ROW was put for the certain entity key. Please see the discussion here: http://forum.hibernate.org/viewtopic.php?t=959868&highlight=getcacheddata... In these situations, this method should probably return null. It is very likely since other calling methods check for the returned value to be 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] Créée: (HHH-2060) To be able to use <generator> with <composite-id>

by Xavier Brénuchon (JIRA)

To be able to use <generator> with <composite-id> ------------------------------------------------- Key: HHH-2060 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2060 Project: Hibernate3 Type: Improvement Versions: 3.2.0.cr4 Environment: Hibernate 3.x Reporter: Xavier Brénuchon Hello, This is the continuation of HB-389 We develop an application which has very strong need for performance with several tens of million recordings. Partitioning is a need. So for that, I use <composite-id>. But my primary key is not a natural key, but a real technical key : - column of partitioning for optimization of the data base - column of technical id So I need to have a generator, for exemple : <composite-id name="id" class="IdPartition"> <key-property name="org" type="string" column="ORG"/> <key-property name="id" type="long" column="ID"/> <generator class="fr.test.xavier.IdPartitionGenerator"> <param name="table">TAB_SEQ</param> <param name="column">LAST</param> </generator> </composite-id> The good news is that Hibernate can use that (HB-389). In fact, it is enough to modify the DTD to authorize <generator> in <composite-id> and it is all. The current code of Hibernate manages it very well. Is it possible that Hibernate is enriched by this functionality? -- 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: (HBX-757) Add output file name, delimiter, halt on error, and format options to SchemaUpdate/<hbm2ddl>

by Dan Ports (JIRA)

Add output file name, delimiter, halt on error, and format options to SchemaUpdate/<hbm2ddl> -------------------------------------------------------------------------------------------- Key: HBX-757 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-757 Project: Hibernate Tools Type: Improvement Components: ant Versions: 3.2beta7 Reporter: Dan Ports Priority: Minor The file name, delimiter, halt on error, and format options are provided by SchemaExport/<hbm2ddl> already, so it makes sense to add their functionality to SchemaUpdate as well. I'll submit a patch shortly. (Is this the right place to post this, since SchemaUpdate is in the Hibernate core SVN?) -- 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-2077) Providing an escape sequence for Criteria queries

by Tobias Dietl (JIRA)

Providing an escape sequence for Criteria queries ------------------------------------------------- Key: HHH-2077 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2077 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4 Environment: Hibernate 3.1.3, MySQL, HSQLDB, Oracle Reporter: Tobias Dietl Up to now, there is no way of setting the escape sequence to use for string comparisions with like for Criteria queries. This is necessary as MySQL on the one hand and HSQLDB / Oracle on the other behave differently... If you want to search for '_abc' in MySQL, you have to use: value like '\\_abc' In Oracle or HsqlDB, you have to use: value like '\_abc' If you want to switch to another escape sequence like '|' , you can set it in HQL with value like '|_abc' escape '|'. Unfortunately, there is no way of setting it for Criteria queries, which would force me to rewrite all my Criteria queries in HQL. It would really be nice if the feature/improvement would be added... -- 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
