Well, this depends (in theory at least :) on the database adaptor. It could just fetch the results up to 20 but usually it will just fetch all and cut the batch out of it. This isnt so bad as it seems because you can have the ZSQL Method cache the result so the database isnt asked any time. You dont need DTML for batching. There is a batch module you can use in python scripts as well (and with ZPT) HTH Tino _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
