-----------------------------------------
Summary: New JPQL keywords no longer usable as aliases
Key: OPENJPA-2948
URL: https://issues.apache.org/jira/browse/OPENJPA-2948
Project: OpenJPA
Issue Type: Sub-task
Components: jpa
Affects Versions: 4.2.0
Reporter: Maxim Solodovnik
Assignee: Romain Manni-Bucau
Fix For: 4.2.0
Discussion link:
https://github.com/apache/openjpa/pull/144#discussion_r3682999074
(medium) identification_variable() only accepts <IDENTIFIER>, so every newly
introduced token (ID, VERSION, RIGHT, ON, NULLS, FIRST, LAST, CAST, STRING,
UNION, INTERSECT, EXCEPT, TREAT, ...) can no longer be used as an
identification variable or result alias. Existing queries like SELECT e.id AS
id ... ORDER BY id or aliases named first/on now fail to parse - a
backward-compat regression worth documenting or mitigating with soft keywords.
