Take a look into
org.hibernate.query.sqm.mutation.internal.cte.CteStrategy which uses DML
in CTEs to implement a delete for polymorphic entities as well as for
cascades.

What do you mean with a CTE mutation strategy?

thanks for the report. As you figured, this is currently not handled.
The method was introduced for a CTE mutation strategy that I rewrote
and the method currently has no real use. I agree though that it
makes sense to make use of it for this purpose.
I don't know if it makes sense to handle this in the SqlAstTranslator
though. It's probably best to do some kind of query splitting for
this. I created https://hibernate.atlassian.net/browse/HHH-14483 for
this. Have to think about it a little though.
