That was a mistake. It should have gone to the mailing list...

In principle, all Zope related messages should go to a mailing
list and not to me privately...

"REQUEST" does *not* know about DTML variables.

I am not familiar with "dictionaries" (it is in fact less
efficient than the use of the result directly).

But, I expect that "dictionaries" is not a method of
the "Z SQLMethod" itself but instead of its result.

If I am right, then you must use "MyZSQLMethod().dictionaries()".

I used the "fields" from your example.

Whatever it is, you can pass it to an "External Method" (or
other function like object). You may need to call it explicitly
to get the same effect as you would get when you used it as
a DTML variable, as I explained above.
