[JIRA] (HHH-15529) Cannot override non-identifier propety from @MappedSuperclass and make it identifier in subclass

JohannesMartin ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNDQ2YjJlYjg3... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15529?atlOrigin=eyJpIjoiNDQ2Yj... ) HHH-15529 ( https://hibernate.atlassian.net/browse/HHH-15529?atlOrigin=eyJpIjoiNDQ2Yj... ) Cannot override non-identifier propety from @MappedSuperclass and make it identifier in subclass ( https://hibernate.atlassian.net/browse/HHH-15529?atlOrigin=eyJpIjoiNDQ2Yj... ) Issue Type: Bug Affects Versions: 5.0.9, 5.6.11, 5.3.28 Assignee: Unassigned Attachments: HHH-xxxxx-MappedSuperclassAndId.zip Components: metamodel Created: 19/Sep/2022 08:59 AM Environment: hibernate-entitymanager (versions see about) OpenJDK 8 Ubuntu 20.04 MySQL Priority: Major Reporter: JohannesMartin ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) I’ve got a @MappedSuperClass A defining field testA as non-identifier. Class B extends Class A, defining additional field testB. Class B annotates both field testA and field testB with @Id. At runtime, hibernate 5.6.11 complains: org.hibernate.MappingException: You cannot override the [testA] non-identifier property from the [sample.entities.A] base class or @MappedSuperclass and make it an identifier in the [sample.entities.B] subclass! Earlier versions just silently ignore the @Id annotation on testA. If I annotate testA as @Id in the MappedSuperclass, the code runs fine, but this violates JPA spec (JPA 2.1 http://download.oracle.com/otndocs/jcp/persistence-2_1-fr-eval-spec ( http://download.oracle.com/otndocs/jcp/persistence-2_1-fr-eval-spec ) - Chapter 2.4): > > > > The primary key must be defined on the entity class that is the root of > the entity hierarchy or on a mapped superclass that is a (direct or > indirect) superclass of all entity classes in the entity hierarchy. The > primary key must be defined exactly once in an entity hierarchy. > > Why does hibernate handle things like this? Is there a way around it.

[JIRA] (HHH-15525) Allow Global- and PersistentTemporaryTableStrategy to participate in hbm2ddl

by Christian Beikov (JIRA)

Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZGJlZWEyMjcy... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-15525?atlOrigin=eyJpIjoiZGJlZW... ) HHH-15525 ( https://hibernate.atlassian.net/browse/HHH-15525?atlOrigin=eyJpIjoiZGJlZW... ) Allow Global- and PersistentTemporaryTableStrategy to participate in hbm2ddl ( https://hibernate.atlassian.net/browse/HHH-15525?atlOrigin=eyJpIjoiZGJlZW... ) Change By: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) [https://hibernate.atlassian.net/browse/HHH-15517|https://hibernate.atlass...] has shown again that the creation of temporary tables might not always be possible with the database user which is used for normal operations. For global and persistent temporary tables, we could emit the DDL in hbm2ddl instead and skip creating/dropping tables during runtime. I suggest we introduce a configuration option for controlling this. We might need new {{Dialect}} methods though which will have to return us something similar to {{SqmMultiTableInsertStrategy}} and {{SqmMultiTableMutationStrategy}}, because the regular methods {{getFallbackSqmInsertStrategy}} and {{getFallbackSqmMutationStrategy}} require the mapping model to be available, which we don’t have in the {{SchemaManagementToolCoordinator}}.

The improvement is to use the SimpleInsertQueryPlan to avoid creating a temporary table.
