[Zope] howto sql-query directly from my products methods?

well, i could instantiate a bunch of zsql methods, each with its own query and then call them from my products methods. but how could i obviate the need to have these zsql methods and query directly? Or is it just not worth it? thx hans -- -------------------------------------------------------------- hans augustin (software developer) hans@beehive.de beehive elektronische medien GmbH http://www.beehive.de phone: +49 30 847-82 0 fax: +49 30 847-82 299
