ORDER BY with many-to-one association doesn't make an outer join with flag : nullable = true -------------------------------------------------------------------------------------------- Key: HHH-5749 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5749 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.0 Reporter: ghanassia I would like to react to the following post : https://forum.hibernate.org/viewtopic.php?f=1&t=949719&view=next Bernard Ligny is right by expected this behiavour : Extract of topic : " But this leads me to the following suggestion: I was wondering if, with the help of the not-null attribute in my <many-to-one> mapping, Hibernate could not smartly utilize such information in order to decide how to translate the implicit join: - if not-null="true" => translated into a normal join - if not-null="false" => translated into an outer join " I think than hibernate will better with this behiavour, for me this is bug to ignore the not-null information in association many-to-one to build SQL request. Of course is possible to write explictly the outer join, but is it realy the philosophy of hibernate ?
