If you're dealing with a database that can handle tree structures natively, maybe. But, I read the articles on doing tree structures as sets and I was ... underwhelmed. If all you need is the next page and there is only ever one next page, then deal with it that way. If you need a true parent-child structure and a way of asking for all parents without wanting to explicitly code it into your SQL and have it handled correctly by the optimizer ... good luck without Oracle or PostgreSQL.

Now, you could build the queries using some module (???), but the queries are very very very slow and very very very difficult to get right. Again, good luck. I wouldn't want to try ...
