recursion

Hi guys,

I have a tree structure where each Node has a parent and a Set<Node> children. Each Node has a String title, and I want to make a query where I select Set<String> titles, being the title of this node and of all parent nodes. How do I write this query?

The query for a single title is this, but like I said, I'd like it expanded for the entire branch of parents.

SELECT node.title FROM Node node WHERE node.id = :id

Cheers

Nik
