[Zope] dtml-in sql => dtml-in anything?

[Joh Johannsen]

Is it possible to replace an existing ZSQL method with an identical
Python External Method that behaves exactly the same way?

So if I have a ZSQL method "GetThingFromDB"

<dtml-in GetStuffFromDB>
 got a <dtml-var thing>
</dtml-in>

Can I replace "GetThingFromDB" with a Python External Method?

I've discovered that if I return a list, then that list gets returned
one item at a time.  But what value does each item have?

I'd like to just have the external method return exactly the same thing
as the ZSQL, but I'm having some problem finding what format (if any)
that is.

Is this sort of thing even possible?

Thanks,

JJ
