Answer 1

Indeed, this seems to be the problem reported in HHH-2225 (that HHH-2536 duplicates). Unfortunately, the issue is not fixed and I'm afraid you'll have to either use HQL or submit a patch (you can start with voting on the issue but I wouldn't expect a fast resolution given that this issue is almost four years old).

Answer 2

Simply way , don't use createNativeQuery , just use createQuery .. or make a transiant with getter convat

Answer 3

We could use currentSession.createQuery() instead of currentSession.createSQLQuery(). The query will be slightly different.
