Hi, In my domain model one of the classes has a surrogate key and a unique key constraint. On attempting a saveOrUpdate for an instance of this object I get a unique key constraint violation error. This is because an insert was issued instead of an update. How can i handle the case when the new instance that needs to be ...

93. unique constraint error with increment generator, 2 db's    forum.hibernate.org

I'm updating two different instances of Oracle while running under Tomcat. The increment generator is using the highest value from the first instance when it generates a new key for the same table in the second instance. This results in a unique key constraint violation. Running a simplified test program in batch works, and Hibernate debug shows 2 calls that fetch ...

95. Changes to be made if I remove the foreign key constraints    forum.hibernate.org

Hi We use hibernate2, java, spring, tomcat and oracle10g. I want to remove the foreign key constraints on one table so that the table no more has many-to-one relation with its parent table. When I do this, I update the hibernate mappings accordingly by removing the one-to-many / many-to-one mappings between the two tables. Will this be sufficient or should I ...

96. Delayed constraint checking?    forum.hibernate.org

Hello, I need to have delayed constraint checks done, i.e. all constraints should be checked at commit time; this allows for temporarily inconsistent states while a transaction is in progress. I encountered two problems there so far: 1) Setting the constraints at the DB level. I tried to subclass Dialect (Oracle9Dialect) to add the known "deferrable initially deferred" clause at "not-null" ...

97. Constraint violation of some statements, update though    forum.hibernate.org

Hi folks, I want to execute several update queries within one transaction. Some of the queries might break a constraint of the table, for example trying to insert an unique value in the table, that already exists. The problem is, if one of the queries failes, the whole transaction failes (atomicity). Is there a way to let the failing queries fail ...

98. version+integrity constraint violation    forum.hibernate.org

Hi, I am trying to add versioning to my classes, in order to support optimistic locking. I have encountered the following problem: what I'm doing is this: 1. clean DB 2. insert entity with id=123 3. other stuff. 4. delete the entity with id 123 (this is through hibernate! session sould be aware of the deletion!) 5. try to insert an ...
