[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

[Hibernate-JIRA] Commented: (HHH-1100) Invalidate cache on StaleObjectStateException

by j nadler (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1100?page=c... ] j nadler commented on HHH-1100: ------------------------------- We're going to patch our Hibernate Core in a way similar to what Nico has done. The alternatives are too intrusive in our application code. Of course this will make it harder for us to upgrade Hibernate in the future. It's disturbing that this issue has sat out there for 5 years. From a naive point of view (not all that familiar with Hibernate internals) it seems low risk to do what Nico has done and evict from L2 in this case. > Invalidate cache on StaleObjectStateException > ---------------------------------------------- > > Key: HHH-1100 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1100 > Project: Hibernate Core > Issue Type: Improvement > Components: core > Reporter: Gavin King > Assignee: Gavin King > Priority: Critical > > We should probably invalidate the second-level cache when a StaleObjectStateException occurs.
