[Hibernate-JIRA] Created: (HHH-2354) Schema validation too rigid for MySql enums

by Zeljko Trogrlic (JIRA)

Schema validation too rigid for MySql enums ------------------------------------------- Key: HHH-2354 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2354 Project: Hibernate3 Type: Bug Components: metamodel Environment: jboss-seam-1.1.0.GA, MySQL 5 Reporter: Zeljko Trogrlic Enum column type in MySQL is handled as CHAR in their JDBC driver and should be mapped to String Java type. However, Hibernate expects varchar(n) and fails to do the validation. This is how DatabaseMetaData.getColumns describes it: DATA_TYPE=1 TYPE_NAME=enum Note that although TYPE_NAME is enum, DATA_TYPE represents CHAR. Hibernate reports following exception: 13:49:31,397 INFO [TableMetadata] table found: configuration.userdb_domain_acl 13:49:31,397 INFO [TableMetadata] columns: [id, enabled, tablename, domain] 13:49:31,397 WARN [ServiceController] Problem starting service persistence.units:ear=msmgui.ear,unitName=msmgui javax.persistence.PersistenceException: org.hibernate.HibernateException: Wrong column type: enabled, expected: varchar( 2) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:698) at org.hibernate.ejb.HibernatePersistence.createContainerEntityManagerFactory(HibernatePersistence.java:127) at org.jboss.ejb3.entity.PersistenceUnitDeployment.start(PersistenceUnitDeployment.java:264) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) Validation should be fixed/relaxed to avoid 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-2193) Introduce a flag to avoid checking NamedQuery at startup

by Emmanuel Bernard (JIRA)

Introduce a flag to avoid checking NamedQuery at startup -------------------------------------------------------- Key: HHH-2193 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2193 Project: Hibernate3 Type: Improvement Components: core Reporter: Emmanuel Bernard Fix For: 3.2.2 With the ratio of 1 query out of 60 entities (60 entities and 10 named queries), checking the named queries at startup takes 7% (specifically the HQLQueryPlan creation).

[Hibernate-JIRA] Created: (EJB-277) allow string values for query hints

by Norman Richards (JIRA)

allow string values for query hints ----------------------------------- Key: EJB-277 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-277 Project: Hibernate Entity Manager Type: Improvement Reporter: Norman Richards It seems that some string values are not accepted as query hint values in hibernate. In specific, I was trying to convert a simple query that uses setHint("org.hibernate.cacheable", true) to use an XML-defined EntityQuery that uses <framework:entity-query name="allCategories" ejbql="select c from Category c" order="c.name"> <framework:hints> <key>org.hibernate.cacheable</key> <value>true</value> </framework:hints> </framework:entity-query> Unfortunately, this fails with an IllegalArgumentException: Caused by: java.lang.IllegalArgumentException: Value for hint at org.hibernate.ejb.QueryImpl.setHint(QueryImpl.java:160) at org.jboss.seam.framework.EntityQuery.createQuery(EntityQuery.java:114) at org.jboss.seam.framework.EntityQuery.getResultList(EntityQuery.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) ... Although I didn't try it, I would assume this would also fail from a @QueryHint in on a named query since that annotation only accepts a string value. I don't think this is technically a bug, but it would be very convenient if all the hints could accept string values. -- 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

[Hibernate-JIRA] Created: (HHH-2407) rework HQL translator

by Steve Ebersole (JIRA)

rework HQL translator --------------------- Key: HHH-2407 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2407 Project: Hibernate3 Type: Improvement Components: query-hql, query-criteria Reporter: Steve Ebersole Assigned to: Steve Ebersole Priority: Blocker Fix For: 3.3 Formalization of the work already started on the HQL_ANTLR_2 branch in SVN. Specifically, split the translation into 4 phases instead of 3 phases (we really sorta, kinda have 4 phases already with the join-post-processor). This is pre-requisite for many requested enhancements to HQL. Also the idea is to consolidate code between HQL and Criteria translation, thus giving Criteria queries all the capabilities available in HQL. -- 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-2629) Enable ordering by association paths

by Jörg Heinicke (JIRA)

Enable ordering by association paths ------------------------------------ Key: HHH-2629 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2629 Project: Hibernate3 Issue Type: Patch Components: query-criteria Affects Versions: 3.2.4.sp1 Reporter: Jörg Heinicke In Hibernate's criteria API ordering is not possible on association properties without explicitly creating aliases. This also only works on one level, not recursively as it would be needed in the following example. Criteria criteria = session.createCriteria(Account.class); Criteria pCriteria = criteria.createCriteria("person"); pCriteria.add(Example.create(person)); pCriteria.createCriteria("company"); criteria.addOrder(Order.asc("person.company.name")); return criteria.list(); I have changed CriteriaQueryTranslator in a way that it first searches the aliasCriteriaMap, second the associationPathCriteriaMap. And the key used for the search is no longer StringHelper.root( propertyName ); but StringHelper.qualifier( propertyName ); >From what I understand this can't break anything since it has always only worked with one '.' in the path. For those cases the key stays the same. This implementation is still not perfect since 1. you need to create criteria in advance 2. you can't switch between alias and actual association path. The best would probably be to walk the path recursively. -- 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
