As javascript is executed on the client, not on the server, where the
sql is, you will need some way for Javascript to talk to Zope without
refreshing the browser window.
I have used the vcXMLRPC library ( http://www.vcdn.org/Public/XMLRPC/
) with great success for this kind of thing. - It should work almost out of
the box as Zope has great support for XMLRPC.

Good luck
