RE: object tree query

[Edwin van der Elst]

Hi,   We did this type of queries for a menu definition (with sub-sub-sub-menu;s etc.).   Datamodel: menu with a relation to itself for the 'parent' relation.   2 Queries: 1 for all menu's, 1 for all the relations of our type (a subclass of Posrel). The creation of the tree was done in memory (it resulted in a javax.swing.Treemodel like structure).   All our code worked on the cloud interface.   Regards,   Edwin van der Elst Finalist IT Group   -----Oorspronkelijk bericht----- Van: Paul van Beukering [mailto:[EMAIL PROTECTED] Verzonden: woensdag 30 juni 2004 14:50 Aan: [EMAIL PROTECTED] Onderwerp: object tree query Imagine, I  have defined an objecttypes products and categories. Products are grouped in categories, these categories can have subcategories...etc, recursive. Is there a way to query an objecttree like this in a single call, or do I have to query for subcategories for every category I find?   Thanks in advance, Paul
