[Zope] Using ZCatalog to catalog SQL data

Listers, I have stored my data in a MySQL table and created Z SQL Methods to access the data for viewing. I am wondering how to now use ZCatalog to create a catalog of the data in the table (and thus a search interface). I tried to catalog the Z SQL Method itself, but that appears to do only that. How do you go one more layer and actually pull the data out of the table and add it to the catalog? Thanks for any help, Chris
