[hibernate-issues] [JIRA] (HHH-16985) Unique keys on unique columns ignore ImplicitNamingStrategy

Georg Echterling ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNmMyMDgzZDk4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16985?atlOrigin=eyJpIjoiNmMyMD... ) HHH-16985 ( https://hibernate.atlassian.net/browse/HHH-16985?atlOrigin=eyJpIjoiNmMyMD... ) Unique keys on unique columns ignore ImplicitNamingStrategy ( https://hibernate.atlassian.net/browse/HHH-16985?atlOrigin=eyJpIjoiNmMyMD... ) Issue Type: Bug Affects Versions: 6.3.0.CR1 Assignee: Unassigned Created: 24/Jul/2023 05:30 AM Priority: Major Reporter: Georg Echterling ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) When using a custom ImplicitNamingStrategy#determineUniqueKeyName , the following mapping only partially applies the intended naming scheme: @Entity @Table( uniqueConstraints = { @UniqueConstraint(columnNames = { "ukColumn1" , "ukColumn2" }) } ) class Parent { @Id Long id; String ukColumn1; String ukColumn2; @Column(unique = true ) String ukAnnotatedColumn; @OneToOne Child child; } The unique key applied via @UniqueConstraint correctly uses ImplicitNamingStrategy#determineUniqueKeyName. The two unique columns ukAnnotatedColumn (via @Column(unique = true) ) and child (via @OneToOne ) still use a hashed key name and ignore the ImplicitNamingStrategy. All unique key names should be consistently generated via ImplicitNamingStrategy#determineUniqueKeyName. Afaict, the unique keys for single unique columns get generated in a different phase from the @UniqueConstraints. When I tried to create a test case for this bug, only the @UniqueConstraint was available via org.hibernate.mapping.Table.getUniqueKeys(). So I don’t know how to create a test case for this issue.
