[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2045) in () result in "unexpected end of subtree"

[Josh Moore (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2045?page=comments#action_24272 ] 

Josh Moore commented on HHH-2045:
---------------------------------

At least for Postgresql, Max, it's not valid :

   omero3=# select * from project where id in ();
   ERROR:  syntax error at or near ")" at character 36
   LINE 1: select * from project where id in ();

whereas:

   omero3=# select * from project where id in (null);
   id | owner_id | group_id | creation_id | update_id | permissions | version | name | description
  ----+----------+----------+-------------+-----------+-------------+---------+------+-------------
   (0 rows)

And, using Postgres, I've not been able to use the "in ()" construct, though I can't remember the first version where I discovered that (could check subversion if anyone's interested.) Never tried to do "in (null)", but a q.setParameterList( "list", null ) certaily failed.

> "in ()" is a valid sql construct and works with previous versions of Hibernate. The new parser throws an "unexpected end of subtree".
> example:
> from Animal an where an.id in ()
> or
> from Animal an where an.id in (:list)
> and input list is an empty list.
> Is this the behavior we want from now on or ?
