> When using Joined Subclass strategy, an entityManager.merge(detatchedSubclassInstance) on a subclass instance result in a query like this:
> insert into HT_TB_AMBIENTECONFIGURADO select ambienteco0_.ID as ID from TB_AMBIENTECONFIGURADO ambienteco0_ inner join TB_AMBIENTE ambienteco0_1_ on ambienteco0_.ID=ambienteco0_1_.ID where ID=33367
> The "WHERE" condition is not using the table alias. The join is made on the same column, so it shouldn't matter from which table it would be get. Even then, Oracle complains with "ORA-00918: column ambiguously defined" as in the stacktrace included at the end of this description.
> The fix is presented by someone with the same problem on a MS SQL Server 2005 database here: http://forums.hibernate.org/viewtopic.php?t=969471
> I have applied his fix and tested. It works correctly, generating a query with the table alias. The fixed class is attached with commentaries marking what has been changed (lines 374 to 383).
