Hi,

I've been dabbling with the nested model set and have managed to get the basics going.

I was using this article: http://www.developer.com/db/article.php/10920_3517366_1

With the database:


CREATE TABLE BreadCrumbLinks(
SiteAreaName  CHAR(32) NOT NULL PRIMARY KEY,
SiteAreaUrl   CHAR(32) NOT NULL,
Lft  INTEGER NOT NULL,
Rgt  INTEGER NOT NULL);

Within this article it explains how to display hte heirachi of any node:


SELECT C.*
FROM    BreadCrumbLinks AS B, BreadCrumbLinks AS C
WHERE   (B.Lft BETWEEN C.Lft AND C.Rgt)
AND     (B.SiteAreaName = 'Ping)
ORDER BY C.Lft

this is all working fine. But the I can't figure out the SQL to display a full tree of all nodes and paths as one statement.

Does anyone know how to achieve this?
Thanks,

Richard
