[Zope] view rendered zsql query without execution?

[Elena Schulz]

Hi,

as the rendered zsql query source is the key for the cached results, it
should be possible to view the source even if the query is failing due to
db-problems.

Has anybody done the trick yet or can give a hint how to do it?

-- Thanks, Elena

PS.: I know the one with <dtml-var "myZsqlMethod(REQUEST, src__=1)"> but
this requires an errorfree execution of the method.
