As described in https://hibernate.atlassian.net/browse/HHH-15517 ( https://hibernate.atlassian.net/browse/HHH-15517 ) , Hibernate 5 performed our insert into ... select without resorting to temporary tables… Are you looking into restoring the previous behavior as well, or should I open a separate issue for that?
