Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMjQxZTRjYWJm... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15627?atlOrigin=eyJpIjoiMjQxZT... ) HHH-15627 ( https://hibernate.atlassian.net/browse/HHH-15627?atlOrigin=eyJpIjoiMjQxZT... ) useless error message of multi-@JoinColumn mapping does not specify referencedColumnName ( https://hibernate.atlassian.net/browse/HHH-15627?atlOrigin=eyJpIjoiMjQxZT... ) Issue Type: Bug Affects Versions: 6.1.4 Assignee: Unassigned Components: hibernate-core Created: 25/Oct/2022 06:48 AM Priority: Major Reporter: Gavin King ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Consider: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "ID" , referencedColumnName = "TID" , insertable = false , updatable = false ) @JoinColumn(name = "TOC_ID" , referencedColumnName = "SECTION_ID" , insertable = false , updatable = false ) @JoinColumn(name = "SECTION_NUMBER_NB" , insertable = false , updatable = false ) ReportSection sourceTocSlide; The third resulting @JoinColumn is missing a referencedColumnName (easy to miss). The error is: org.hibernate.MappingException: Logical column name cannot be null That’s … pretty bad.
