[Zope] Passing Namespace Arguments to ZSQL Methods

[Casey Duncan]

The other day I learned a useful trick with ZSQL
methods that I thought I would share.

Normally ZSQL methods look only in the REQUEST object
for their arguments. I have had an occasion though
where it would be useful to pass arguments directly
from the namespace just like other methods, without
having to write nonsense like
sqlMethod(arg1=arg1,arg2=arg2,...).

I found that if you pass the ZSQL method the
underscore variable (_) as an argument, it will pull
its arguments from the namespace and not just REQUEST.
example:

<dtml-call expr="sqlMethod(_)">

I hope others of you out there find this trick
beneficial as well.
