[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2460) Multiple object creates on HQL select causes "unexpected token: , "
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2460?page=c...
]
Jesse Sweetland commented on HHH-2460:
--------------------------------------
EJB3 Persistence spec states in section 4.14 (EJB-QL BNF definition) that a select_clause
is one or more select_expressions separated by commas, and a select_expression can be a
constructor_expression. This seems to indicate that this syntax is valid (per spec) and
that this is a legitimate issue.
Multiple object creates on HQL select causes "unexpected token:
,"
------------------------------------------------------------------
Key: HHH-2460
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2460
Project: Hibernate Core
Issue Type: Bug
Components: query-hql
Affects Versions: 3.1.2
Environment: MySQL
Reporter: Steve Mayhew
When executing this query:
select new java.lang.String('test1'), new java.lang.String('test2')
from SomeMappedClass
You get a syntax error. It does not matter what is in the from clause, result is always
the same.
