[Zope-dev] Using db_connections from Zope products

[Tom Brown]

Thanks fo the info!  I had seen those How-Tos... but
was really asking.. How can I use APIs directly
instead of having an External ZSQL method.  I have
created a product and would like to be able to do sql
queries in order to populate members of my class.  For
this example, I have the creation of  a selection box
as a member and the options will be generated by a
select statement.
I have gone through the product creation how to and
was able to add, etc, my object.  I can display html,
make dtml on the fly, etc.. from an object, just
wanted to do a query as well.   .. would like to be
able to do something like the Connection class without
management interface, etc, or use pieces, just not
sure how
