Since this email, I found some help in Zope Book, but still I have
error.
I have an "update" ZSQL method, the argument is 'id'.
If I call it from python script in this way:
------------------
for result in context.updateState(id):
------------------

I get an error.

Error Type: Bad Request
Error Value: ['id']

File
/usr/local/zope/Zope-2.3.3-linux2-x86/lib/python/Shared/DC/ZRDB/Aqueduct.py,

line 150, in _argdata
(Object: updateMLState)
Bad Request: (see above)
-----------

What is the problem.

    Thanks:
