Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZmY4Y2IxMDU1... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16584?atlOrigin=eyJpIjoiZmY4Y2... ) HHH-16584 ( https://hibernate.atlassian.net/browse/HHH-16584?atlOrigin=eyJpIjoiZmY4Y2... ) @JoinTable @ManyToOne should have a unique constraint on association tab;e ( https://hibernate.atlassian.net/browse/HHH-16584?atlOrigin=eyJpIjoiZmY4Y2... ) Issue Type: Bug Assignee: Unassigned Components: hibernate-core Created: 11/May/2023 01:32 AM Priority: Major Reporter: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) A mapping like this: static class Book { @Id @GeneratedValue long id; @ManyToOne @JoinTable(name= "BOOKPUBLISHER" ) Publisher publisher; } Results in this DDL: create table BOOKPUBLISHER ( publisher_id bigint , id bigint not null , primary key (id) ) But the id column should have a unique constraint. The same issue occurs for @OneToOne , where both columns should have unique constraints, but only one unique constraint is added.
