I got help from one of our DBA's today here is what I was missing. This
in not
in Bruce's Book.
INSERT INTO address (per_id,street_num,city,state,zip)
SELECT per_id,'$3','$4','$5','$6' FROM from person
WHERE last = '$1'
AND first = '$2';
$1-6 will be supplied by user input from Zope, I just wanted to isolate
the
per_id from person during and Insert so that end users would not need to
know
it was there. I know I might have a problem with getting more then one
return for
just first and last, I might add more WHERE statements in there. I am
just happy to get moving on with my little project.
Thanks for the help
Richad
