I'm trying to do a bulk update query like this: update Foo | set status = 99 | where address.city = :x | This isn't working. It's throwing an SQL error: javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute update query | caused by | org.postgresql.util.PSQLException: ERROR: syntax error at or near "," (I'm only posting the two relevant lines here.) I looked at the http://www.hibernate.org/hib_docs/entitymanager/reference/en/html/batch.h... and saw: anonymous wrote : No joins (either implicit or explicit) can be specified in a bulk EJB-QL query. I assume this is the limitation I'm running into here. Should I re-write this as a native query? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4029937#...
