[Zope] Z SQL Method multiple column update

[Donald Braman]

I'm setting up a data entry/data update form for legal cases. Each case has
a few documents associated with it. The person entering data enters the
number of documents, a script creates necessary records, then presents them
with a screen that should look a bit like this, with every datum being
updateable:

 doc |title           |source      | pages   | ...
+----+----------------+------------+---------+
| 01 |title of doc 1  |doc1 source | # of pgs| ...
+----+----------------+------------+---------+
| 02 |title of doc 2  |doc2 source | # of pgs| ...
+----+----------------+------------+---------+
| 03 |title of doc 3  |doc3 source | # of pgs| ...
+----+----------------+------------+---------+
...etc.

This is so they can enter data about many documents on a single screen. I'm
not sure how to bind multiple rows/records to a single Z SQL Method. Any
suggestions?
