SQL Method sqlSelectChildren: ---

There seems to be no answer to this question available yet (??), although I'd like to find a solution (the above "solution" does not work..)

Actually, no, it does work. I'm using it (well, a variation of it) quite happily every day.

Maybe someone can give us a simpler example for building a tree with a database method (hope this is not a FAQ)? I remember having seen something here a long time ago, but finding the right keywords for a search in a Zope mail folder with over 9000 mails is not that easy ;-)

For Oracle users, also look at the 'connect by prior' arguments to the select statement. Anthony -- Anthony Baxter <anthony@interlink.com.au> It's never too late to have a happy childhood.
