[Hibernate-JIRA] Created: (HHH-4042) StatelessSession does not flush when using jdbc batch_size > 1

by Gael Beaudoin (JIRA)

StatelessSession does not flush when using jdbc batch_size > 1 -------------------------------------------------------------- Key: HHH-4042 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4042 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.3.1 Environment: JBoss 4.2.3, Linux, java 1.6, hibernate 3.3.1, entityManager 3.4.0, jboss seam 2.1.2, postgresql 8.3 Reporter: Gael Beaudoin I'm using a StetelessSession to insert millions of rows : it works great and without using much memory. But I've just seen that with a jdbc batch size of 50 for example (<property name="hibernate.jdbc.batch_size" value="0"/> in my persistence.xml) the last round of inserts aren't flushed to the database. For example, with 70 insert, only the first 50 are sent to the database. I've searched a lot about this issues and on this thread (https://forum.hibernate.org/viewtopic.php?f=1&t=987882&start=0), the only solution found is to set the batch_size to 1, which is really a shame. I've tried to flush the session, close the jdbc connection, etc etc ... no luck. I'd be fine with a way to set the batch_size to 1 only for this method, pro grammatically, but I've not found any way to do that. If you don't pay attention, it's a easy way to lose data. -- 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-2319) StatelessInterceptor

by Max Rydahl Andersen (JIRA)

StatelessInterceptor -------------------- Key: HHH-2319 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2319 Project: Hibernate3 Type: New Feature Components: core Versions: 3.2.1 Reporter: Max Rydahl Andersen It would make sense to have an Interceptor for StatelessSession to solve the following usecases: Log/adjust SQL: onPrepareStatement Proper entityname handling: instantiate/getEntity Maybe also tx interaction: afterTransationBegin/beforeTransactionCompletion/afterTransactionCompletion Technically it could be solved by just allowing to pass in a normal interceptor to a StatelessSession and just document that the state oriented callbacks will not be called. Alternatively we can create a StatelessInterceptor that only implement the releavant methods and wrap that instance into an internal Interceptor. -- 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-2007) Hibernate doesn't support optional one-to-one associations

by Andrei Iltchenko (JIRA)

Hibernate doesn't support optional one-to-one associations ---------------------------------------------------------- Key: HHH-2007 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2007 Project: Hibernate3 Type: Bug Components: core Versions: 3.2.0.cr2 Reporter: Andrei Iltchenko Hibernate doesn't properly support optional one-to-one associations, e.g. Person (0..1) -- (0..1) Passport. The Hibernate books and reference all talk of two ways of mapping one-to-one associations: 1. using a many-to-one fk association with a unique constraint on the fk; 2. using a pk association. the trouble with both of them is that they enforce the mandatory property of an association end, which sometimes is not desirable. The first way enforces the mandatory property with the uniqueness constraint on the fk, the other by using the fact that one table's pk is its fk. I tried to see if I could adapt the 1st way of representing one-to-ones to support optional association ends. What I did was simply remove the unique and not null constrains from DDL generated (without removing it it would be impossible to have a Person record that doesn't reference a Passport record): from CREATE TABLE Person ( PassUniqueId VARCHAR (32) NOT NULL, version INTEGER NOT NULL, uniqueId VARCHAR (32) NOT NULL, name VARCHAR (40) NULL, PRIMARY KEY (uniqueId), UNIQUE(PassUniqueId), FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId) ); to CREATE TABLE Person ( PassUniqueId VARCHAR (32) NULL, version INTEGER NOT NULL, uniqueId VARCHAR (32) NOT NULL, name VARCHAR (40) NULL, PRIMARY KEY (uniqueId), FOREIGN KEY (PassUniqueId) REFERENCES Passport (uniqueId) ); but leave the uniqueness attribute in the mapping file: <many-to-one name="pass" class="application.business.logic.Passport" cascade="save-update,merge" unique="true" > <column name="PassUniqueId"/> </many-to-one> The resulting solution worked fine and I was able to create instances of Person not linked to a Passport. However Hibernate didn't succed in keeping the association from degrading into a many-to-one. It enabled me to create two Persons linked with the same Passport: PASSUNIQUEID | VIRSION | UNIQUEID | Name ================================================ 0d8b3919fffff | 1 | 0d5fb1dcfff | John 0d8b3919fffff | 0 | 10fd07bdfff | Sam A subsequent attempt at retrieving such Persons with Hibernate failed: org.hibernate.HibernateException: More than one row with the given identifier was found: 0d8b3919ffffffd60151e135b6da0164, for class: application.business.logic.Passport. Hibernate should be able to impose the single end property of such associations without relying on the underlying RDBMS engine and never allow them to degrade to many-to-ones. -- 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: (HV-24) Improve the default message of InvalidStateException

by Mike Quilleash (JIRA)

Improve the default message of InvalidStateException ---------------------------------------------------- Key: HV-24 URL: http://opensource.atlassian.com/projects/hibernate/browse/HV-24 Project: Hibernate Validator Issue Type: Improvement Components: engine Affects Versions: 3.0.0.ga Environment: Any Reporter: Mike Quilleash Doing a printStackTrace on InvalidStateException does not give the actual invalid values anywhere. Would greatly improving debugging speed if this was included by default as often this indicates a programming error. Currently I have to run the code again and debug the right place to find out what the InvalidValues are. -- 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-4618) Support pagination: total rows ignore limit

by Dave (JIRA)

Support pagination: total rows ignore limit ------------------------------------------- Key: HHH-4618 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4618 Project: Hibernate Core Issue Type: New Feature Components: core Environment: JBoss 5.1.0GA Reporter: Dave Limit is used for pagination, but total number of rows must be known to calculate page count. Currently we have to use two queries: 1. select * from Student where age<30 limit 20; 2. select count(*) from Student where age<30; For complex query with joins/huge tables, it can be a performance issue. For Criteria API query with group by, there is no way to get row count, for example criteria.setProjection(Projection.projectionList().add(Projections.groupProperty("name")).add(Projections.sum(score))); Currently there is no way to get row count of this query using Criteria API. For MYSQL, SQL_CALC_FOUND_ROWS and FOUND_ROWS() are used to get row count ignoring limit. Pagination is used for all web application. Hibernate should support it in HQL and Criteria API. -- 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
