[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

[Hibernate-JIRA] Created: (HHH-3854) Issue with greedy loading of associations (default-lazy=false )

by Amar Singh (JIRA)

Issue with greedy loading of associations (default-lazy=false ) --------------------------------------------------------------- Key: HHH-3854 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3854 Project: Hibernate Core Issue Type: Bug Components: envers Environment: Hibernate - core 3.4.0-SNAPSHOT, Hibernate-envers (from trunk) Reporter: Amar Singh Attachments: greedy-loading.zip I have an Entity GP which has a many to one association to entity CA. <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="org.hibernate.envers.test.integration.onetoone.bidirectional" default-lazy="false"> <class name="BidirectionalRefIngPK" table="BIDIRECTIONAL_REFERENCING_ENTITY"> <id name="id" type="long" column="BIDIRECTIONAL_REFERENCING_ID" > <generator class="native"/> </id> <property name="data"/> <many-to-one name="reference" cascade="save-update" class="BidirectionalRefEdPK" column="BIDIRECTIONAL_REFERENCED_ID"/> </class> <class name="BidirectionalRefEdPK" table="BIDIRECTIONAL_REFERENCED_ENTITY"> <id name="longId" type="long" column="BIDIRECTIONAL_REFERENCED_ID"> <generator class="native"/> </id> <property name="data"/> </class> </hibernate-mapping> With this when I load a previous version of BidirectionalRefIngPK, the loading mechanism tries to create a proxy for BidirectionalRefEdPK, but in my case lazy is false so an internal call to createProxy will return NULL hence . This happens in ToOneIdMapper.java in method mapToEntityFromMap around line 82, which then internally calls for AbstractEntityTuplizer.java line 395 for getProxyFactory() ending in NULL pointer exception because proxy factory is null as mine is a greedy loading. TO REPRODUCE ~~~~~~~~~~~~~ Please find a zipped folder attached. The zipped file has 4 files: - GreedyLoading.java (actual testng test case) - BidirectionalRefEdPK.java (Entity 1) - BidirectionalRefIngPK.java (Entity 2) - greedyloading.hbm.xml Please place the three java files in its package (org.hibernate.envers.test.integration.onetoone.bidirectional), couldn't find the right package so created test case accordingly. Put the greedyloading.hbm.xml in src/test/resources. Now when testng runs GreedyLoading.java you should see NPE. -- 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-2891) Query cache fails on many-to-many select

Query cache fails on many-to-many select ---------------------------------------- Key: HHH-2891 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2891 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.5 Reporter: Oleg Efimov I have two entities, User and Group, with many-to-many relation: -------------------------------------------------------------------------------------------------- User.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="test.hibernate"> <class name="User" table="`USER`"> <id name="id" type="long" unsaved-value="null"> <column name="USER_ID" not-null="true"/> <generator class="native"/> </id> <property name="login"> <column name="LOGIN" not-null="true" length="255"/> </property> <bag name="groups" table="USER_GROUP" lazy="false" cascade="none"> <key column="USER_ID"/> <many-to-many class="Group" column="GROUP_ID"/> </bag> </class> </hibernate-mapping> -------------------------------------------------------------------------------------------------- Group.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="test.hibernate"> <class name="Group" table="`GROUP`"> <id name="id" type="long" unsaved-value="null"> <column name="GROUP_ID" not-null="true"/> <generator class="native"/> </id> <property name="name"> <column name="GROUPNAME" not-null="true" length="100"/> </property> <bag name="users" table="USER_GROUP" lazy="true" inverse="true" cascade="all-delete-orphan"> <key column="GROUP_ID"/> <many-to-many class="User" column="USER_ID"/> </bag> </class> <query name="Group.select.by.login" cacheable="true"><![CDATA[ select user.groups from User user where user.login=? ]]> </query> </hibernate-mapping> ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- test.hibernate.User and test.hibernate.Group classes are just simple beans. In Group.hbm.xml there is a query called "Group.select.by.login", it's intended to be cached. So I add corresponding properties to Hibernate configuraition: -------------------------------------------------------------------------------------------------- properties.put("hibernate.cache.provider_class", "org.hibernate.cache.EhCacheProvider"); properties.put("hibernate.cache.use_query_cache", "true"); ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Configuration has no extra parameters. Then I'm trying to execute the query two times: -------------------------------------------------------------------------------------------------- test fragment SessionFactory sessionFactory = configuration.buildSessionFactory(); Session session = null; try { session = sessionFactory.openSession(); Query query = session.getNamedQuery("Group.select.by.login"); List<Group> groups; groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two Group objects, ok +++++++++++++++ System.out.println("-----------------------------------------------------------------------------------"); for (Group group : groups) { System.out.println(group.getName()); } System.out.println("-----------------------------------------------------------------------------------"); groups = query.setParameter(0, "admin").list(); // +++++++++++++++This list() returns list of two nulls +++++++++++++++ System.out.println("-----------------------------------------------------------------------------------"); for (Group group : groups) { System.out.println(group.getName()); } System.out.println("-----------------------------------------------------------------------------------"); } finally { if (session != null) { session.close(); } sessionFactory.close(); } ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The first query returns list of, in my case, two groups. The second query returns list of two nulls instead of the same list. I've investigated the problem, and found the following: Query return value is "user.groups", and during query analysis (org.hibernate.hql.ast.QueryTranslatorImpl:160) query return type is defined as "org.hibernate.type.BagType(test.hibernate.User.groups)". This seems to be the problem, as during query put operation org.hibernate.CollectionType.disassemble is called (org.hibernate.cache.StandardQueryCache:80), which simply returns null as owner is null. If this query is not a misuse, then I think, something is to be done at the time of analysis, so that return type be somewhat different.

[Hibernate-JIRA] Created: (HHH-2049) LEFT OUTER JOIN subcriteria filters children

by Mattias Jiderhamn (JIRA)

LEFT OUTER JOIN subcriteria filters children -------------------------------------------- Key: HHH-2049 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2049 Project: Hibernate3 Type: Bug Components: query-criteria Versions: 3.1.3, 3.2.0.cr4 Environment: Hibernate 3.1.3/3.2.0rc4, hsqldb 1.8 Reporter: Mattias Jiderhamn Attachments: SubCriteriaTestCase.zip When using the Criteria API with LEFT OUTER JOIN to add criterias to the children, i.e. criteria.createCriteria("children", JoinFragment.LEFT_OUTER_JOIN) the child collections will only contain those children matching the criteria. (Even when *not* using any Filters).

[Hibernate-JIRA] Created: (HHH-3795) Unexpected behaviour of saveOrUpdate() for associations with delete-orphan

by Fabian Dankof (JIRA)

Unexpected behaviour of saveOrUpdate() for associations with delete-orphan -------------------------------------------------------------------------- Key: HHH-3795 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3795 Project: Hibernate Core Issue Type: Improvement Environment: Hibernate 3.2.6.GA, PostgreSQL 8.3 Reporter: Fabian Dankof Hello there, I think saveOrUpdate() behaves somewhat unexpected for associations with delete-orphan cascading style: Prerequisite: Association is set to cascade="all,delete-orphan" and nullable=true 1) Within a single session (i.e. a transient object): * Load parent * Delete child * saveOrUpdate() Result: Child is deleted from DB, a DELETE statement was issued 2) Across multiple session (i.e. a detached object): * Have parent with valid ID, but empty list/set of children * saveOrUpdate() Result: Child is not deleted from DB, an UPDATE statement is issued which sets FK of child to 'null' 3) like 2) but nullable is FALSE Result: Nothing happens. With merge() everything works as expected for detached and transient instances. I would either expect saveOrUpdate() to completely disregard DELETE statements OR behave similar to merge(). At least the different results of case 1) and 2) are pretty confusing.
