Joins are currently not supported for mutation queries in Hibernate 6. I also tested your example with Hibernate 5.6 since you reported it was working but it did not work for me. One way to work around this would be using a subquery, something like: update PrivateSubData psd set psd.dataName = '...' where psd. data.id in ( select data.id from PrivateData data where data.person.id = ?1) ( https://hibernate.atlassian.net/browse/HHH-16615#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16615#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
