Donnchadh O Donnabhain commented on HHH-3352:
---------------------------------------------

similarly for joined tables (e.g. <join table="my_table"><property ... />...</join> that aren't part of the inheritance hierarchy) where the fields in the joined aren't being updated.

> Updating of entities in an inheritance hierarchy with the JOINED strategy.
> Trying to update all entities of this hierarchy using a hql statement that affects attributes/columns
> of the base entity only doesn't need the insert into TEMP / Update BASE_TABLE / delete TEMP logic
> Update BASE_TABLE is sufficient and more efficient.
