[Hibernate-issues] [Hibernate-JIRA] Closed: (HB-38) HQL access to collection members by [index]

[<leg...@at...>]

Message:

   The following issue has been closed.

   Resolver: Gavin King

This is now implemented, as:

select mapElement 
from Foo foo 
join foo.map mapElement 
where index(mapElement) = 'foo'

The index() function may even appear in the select clause.

Note that path expressions with [] may still not appear in the select or from clauses.

Description:
HQL access to collection members
Please extend HQL to allow access to instances 
mapped to collections, something like this: 

if names is a list: 
"select e.names[0] from e in class Element" 

if names is a map: 
"select e.names("primary") from e in class Element" 

Null should be returned if either lookup fails.
