RE: [PHP] Tough Select List with multiple arrays

Probably completely off topic but as far as tough select statements go heres a beauty our oracle dba came up with the other day SELECT /*+ORDERED*/ a.id, a.name, a.parent_type_ref, a.h_level, f.children, COUNT(b.media_title_ref) no_titles FROM (SELECT c.id, c.name, NVL(c.parent_type_ref, 0) parent_type_ref, LEVEL h_level, c.client_ref FROM dt_types c WHERE c.type_type = dp_constants.ccategory START WITH c.parent_type_ref IS NULL CONNECT BY PRIOR c.id = c.parent_type_ref GROUP BY c.id, c.name, parent_type_ref, LEVEL, c.client_ref) a, dt_client_media_categories b, (SELECT d.id, COUNT(e.parent_type_ref) children FROM dt_types d, dt_types e WHERE e.parent_type_ref(+) = d.id AND d.type_type(+) = dp_constants.ccategory AND e.type_type(+) = dp_constants.ccategory GROUP BY d.id) f WHERE a.id = b.category_ref(+) AND a.client_ref = b.client_ref(+) AND a.client_ref = pclient_id AND a.id = f.id GROUP BY a.id, a.name, a.parent_type_ref, a.h_level, f.children ORDER BY a.h_level; this gets a nice hierarchy of categories, how many items in each categories category levels etc.. all done in one query that takes 3msec on a sparc ultra 5 ..
