I finded bug in Hibernate 3.1.3 version, that was not in 3.1.2.

Try HQL DML like this:



delete from IdfKlient vstp where exists(from Dotaz as dotaz where dotaz.davka=:davka and vstp.dotaz=dotaz)

Hibernate 3.1.2 transaltes as:

Hibernate: delete from idfklient where exists (select dotaz1_.id from dotaz dotaz1_ where iddavky=? and dotaz_id=id)


But in Hibernate 3.1.3:

Hibernate: delete from idfklient where exists (select dotaz1_.id from dotaz dotaz1_ where dotaz1_.iddavky=? and idfklient0_.dotaz_id=id)

And fails!

Do you have same problems? If so I will report in JIRA.
