Steve Ebersole commented on HHH-2408:
-------------------------------------

I love how people come here all irate about something they cant even research...

Section 4.10
{quote}
Bulk update and delete operations apply to entities of a single entity class (together with its subclasses,
if any). Only one entity abstract schema type may be specified in the FROM or UPDATE clause.
{quote}

Pretty plain English.  Perhaps y'all are confused with the term "abstract schema type" that the specification uses throughout.  But I assure you this is not supported (not even in JPQL!)

> When generating SQL for statements like this: UPDATE Issue i SET i.dueDate = i.dueDate + 10 WHERE i.visit.branch.id = :branchId, an extra comma is generated at the end of table list: update Issue,  set DUE_DATE=DUE_DATE+10 where BRANCH_ID=?
