[hibernate-issues] [Hibernate-JIRA] Commented: (EJB-403) QueryTest - Native Query for Update using alias causes failure

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/EJB-403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32053#action_32053 ] 

Emmanuel Bernard commented on EJB-403:
--------------------------------------

The patch is not solving the root problem.
identification variables in update statements are legal as per the JPA spec. 
The proper fix is to generate a SQL that "removes" the identification variable for PostgreSQL (probably triggered by a Dialect flag).
Let's open a Hibernate Core JIRA for it and see what Steve has to say.

In the mean time, let's treat that as a limitation of PostgreSQL and a known failing test.

> Even though it says in documentation that it supports table aliases in "update" clauses[1], the below test fails when using it. Removing the table alias is enough to make it successful.
