[Hibernate-JIRA] Created: (HHH-2614) Blob Length Set to 255 By Default With Derby DB

by Sean Sylvis (JIRA)

Blob Length Set to 255 By Default With Derby DB ----------------------------------------------- Key: HHH-2614 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2614 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3 Environment: Apache Derby 10.2.2, Java 1.6.0 Reporter: Sean Sylvis When the (Hibernate) type "blob" is used in an object mapping file and a length is not specified, Hibernate converts this type as "blob (255)" to the Apache Derby database table definition. (This seems to be the same as the conversion behavior of a Java String to "varchar (255).") The same behavior results when using a CustomType that returns a Java SQL Types.BLOB. This is not the behavior I expected. Hibernate converts the same type as simply "blob" (which has a maximum length of 65535 bytes when no length is specified) when using MySQL version 5.0 (http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html). Furthermore, the Derby specification (http://db.apache.org/derby/docs/10.2/ref/rrefblob.html) states that a blob type without a length value will default to a length of 2M-1 bytes. I could not find a length specification for the Java SQL Blob type (http://java.sun.com/javase/6/docs/api/), but the current default length does seem to conform to other Hibernate type standards. That is, if a length is not specified, the length defaults to the maximum length defined for that type by the database. -- 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-3240) In Derby field type 'text' is converted to CLOB(255)

by Aleksander Rozman (JIRA)

In Derby field type 'text' is converted to CLOB(255) ---------------------------------------------------- Key: HHH-3240 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3240 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.1 Environment: Hibernate 3.1, Derby 10.3.2.1 Reporter: Aleksander Rozman Priority: Blocker When using type 'text' this is incorectly converted to CLOB(255). Derby has several long var char types which could be used instead, but instead it's defaulted to clob(255). I have taken a look at source from 3.1 and 3.2.6 (latest) and this code is still the same... I think that just little fix in DerbyDialect would be enough... I would try this myself but I am currently lacking time and resources. I hope this will be taken care of as soon as it gets... -- 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-5160) Error on binding values prepared statment in many-to-any relation

by wof (JIRA)

Error on binding values prepared statment in many-to-any relation ----------------------------------------------------------------- Key: HHH-5160 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5160 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1, 3.3.2 Environment: Tested on Version 3.3.2 and 3.5.1 on Oracle, PostgreSQL and MySQL Reporter: wof A Collection of Entities is defined as a ManyToAny relation, e.g. @ManyToAny(metaColumn=@Column(name="C_OBJECT_TYPE")) @AnyMetaDef(idType="string", metaType="string", metaValues={ @MetaValue(targetEntity=Entity1.class, value="Entity1"), @MetaValue(targetEntity=Entity2.class, value="Entity2") }) @JoinTable(name="T_OBJECTS", joinColumns=@JoinColumn(name="C_OWNER_ID"), inverseJoinColumns=@JoinColumn(name="C_OBJECT_ID") ) private Set<EntityBase> objects = new HashSet<EntityBase>(); Adding to this set works without problems. Removing all elements from the set (i.e. setting the set to null or zero-sized), too. However, when one or more elements are removed from the set with at least one element remaining, an exception is thrown: org.hibernate.exception.GenericJDBCException: could not delete collection rows with the cause being java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2). I have narrowed this problem to this: The mapping table consists of 3 columns, C_OWNER_ID, C_OBJECT_TYPE and C_OBJECT_ID. The generated SQL-statement to delete the rows is as folling: DELETE FROM t_objects WHERE c_owner_id=? AND c_object_id=? However, Hibernate (in org.hibernate.typ.AnyType) tries to bind the actual value for c_object_id with index 3 which causes the exception. I guess Hibernate expects c_object_type to be present in the statement. As workaround we changed nullSafeSet in AnyType to: public void nullSafeSet(PreparedStatement st, Object value, int index, boolean[] settable, SessionImplementor session) throws HibernateException, SQLException { Serializable id; String entityName; if (value==null) { id=null; entityName=null; } else { entityName = session.bestGuessEntityName(value); id = ForeignKeys.getEntityIdentifierIfNotUnsaved(entityName, value, session); } // metaType is assumed to be single-column type // <ORIGINAL CODE> /* if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); } if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } */ // </ORIGINAL CODE> // <PATCHED CODE> if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } else if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index, idsettable, session); } // </PATCHED CODE> } best regards wof -- 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-5043) Incorrect handling of hibernate.default_schema in SchemaUpdate

by Vladimir Klyushnikov (JIRA)

Incorrect handling of hibernate.default_schema in SchemaUpdate -------------------------------------------------------------- Key: HHH-5043 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5043 Project: Hibernate Core Issue Type: Patch Components: core Affects Versions: 3.5.0-CR-2 Environment: Hibernate Core 3.5.0-CR-2, Oracle 10.2 Reporter: Vladimir Klyushnikov Attachments: cfg.patch While HHH-735 fixes default_schema handling in general, it still has a bug.

[Hibernate-JIRA] Created: (HHH-2085) org.hibernate.event.def.DefaultLoadEventListener logs exception at info level

by Don Smith (JIRA)

org.hibernate.event.def.DefaultLoadEventListener logs exception at info level ----------------------------------------------------------------------------- Key: HHH-2085 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2085 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Environment: Hibernate 3.2.0.cr2, MySQL 4.0.18 Reporter: Don Smith Priority: Minor Prior to schema generation, accessing a persistent object throws an exception, as expected. The org.hibernate.event.def.DefaultLoadEventListener logs the exception at the info level, which just adds noise to the application console, and prevents application exception handling (in my case it's valid if the table doesn't exist, so I just want to catch the exception and continue). This log statement should be removed, or moved to a debug or trace level, so it won't show up in normal execution.

[Hibernate-JIRA] Created: (HHH-5858) Cannot load entities with Clob or Lob properties into stateless sessions

by James Roper (JIRA)

Cannot load entities with Clob or Lob properties into stateless sessions ------------------------------------------------------------------------ Key: HHH-5858 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5858 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1 Reporter: James Roper I have a an entity with a Clob property: {code:java} @Lob private Clob clobProperty; {code} When I try and load it in a stateless session, I get: {noformat} Exception in thread "main" java.lang.ClassCastException: org.hibernate.impl.StatelessSessionImpl cannot be cast to org.hibernate.engine.jdbc.LobCreationContext at org.hibernate.Hibernate.getLobCreator(Hibernate.java:420) at org.hibernate.type.ClobType.nullSafeGet(ClobType.java:114) at org.hibernate.type.AbstractType.hydrate(AbstractType.java:105) at org.hibernate.persister.entity.AbstractEntityPersister.hydrate(AbstractEntityPersister.java:2267) at org.hibernate.loader.Loader.loadFromResultSet(Loader.java:1423) at org.hibernate.loader.Loader.instanceNotYetLoaded(Loader.java:1351) at org.hibernate.loader.Loader.getRow(Loader.java:1251) at org.hibernate.loader.Loader.getRowFromResultSet(Loader.java:619) at org.hibernate.loader.Loader.loadSingleRow(Loader.java:307) at org.hibernate.impl.ScrollableResultsImpl.prepareCurrentRow(ScrollableResultsImpl.java:254) at org.hibernate.impl.ScrollableResultsImpl.next(ScrollableResultsImpl.java:123) {noformat} If Lobs in stateless sessions isn't supported, then at very least an error message to that effect should be thrown and the docs should be updated to reflect this, but I don't see why that should be the case, especially considering that both Lobs and stateless session both serve very similar purposes, they are for use when dealing with large datasets that may not fit in memory, and so could well be used together. -- 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-4808) SessionImpl.initializeCollection() does not release JDBC connection (if outside of a transaction)

by Martin Renner (JIRA)

SessionImpl.initializeCollection() does not release JDBC connection (if outside of a transaction) ------------------------------------------------------------------------------------------------- Key: HHH-4808 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4808 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.2, 3.2.7 Reporter: Martin Renner Priority: Critical With {{ConnectionReleaseMode.AFTER_TRANSACTION}} (the default), Hibernate does not release the JDBC connection when resolving a lazily loaded collection, if this happens *outside* of an active transaction. First, I will describe, what happens if Hibernate executes a query outside of a transaction. Then I will describe how lazy collection loading behaves differently. When the method {{list}} of a query ({{QueryImpl.java}}) is getting called, Hibernate delegates to {{SessionImpl.list()}}. After having loaded the list, {{SessionImpl.list()}} calls {{SessionImpl.afterOperation()}}, which calls {{jdbcContext.afterNontransactionalQuery()}} (as there is no active transaction). This leads to {{ConnectionManager.afterTransaction()}} which releases the JDBC connection. This is exactly what I expect to happen. Now to the lazily loaded collection: {{Hibernate.initialize(collection)}} and {{person.getPets().size()}} both end up in {{SessionImpl.initializeCollection()}}. This call gets dispatched down to {{Loader.doQueryAndInitializeNonLazyCollections()}} and {{Loader.doQuery()}}. The important fact is, that {{ConnectionManager.afterTransaction()}} never gets called (like in the query-example above). The result is, that the JDBC connection is not released. IMHO resolving of a lazily loaded collection should behave like executing a query. {{SessionImpl.initializeCollection()}} should call {{SessionImpl.afterOperation()}} in the same way as {{SessionImpl.list()}} is doing this. I will attach a small demo application which shows the difference (concerning {{ConnectionManager}}) between queries and collections. -- 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-3307) HQL query translation in real SQL ignores the dialect class

by Thomas Schilf (JIRA)

HQL query translation in real SQL ignores the dialect class ----------------------------------------------------------- Key: HHH-3307 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3307 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.6 Environment: dialect file with special JoinFragment and a "transformSelectString" step Reporter: Thomas Schilf We're using a special dialect class for a database. In the dialect is defined a own JoinFragment and a "transformSelectString" step. All workes fine by loading objects over a Criteria class. The generated SQL string is wrong by using named queries (HQL). The SQL string is in normal ANSI-SQL. The SqlGenerator and QueryTranslatorImpl classes from hibernate don't use the dialect class. -- 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
