Jose,

Sounds like you walked into a real beauty.

 But your statement:  "by this I mean there is no error message, yet I 
know the application doesnt work right, since no data were inserted into 
the database" sounds more like a programming error and its unclear how 
"logging" will solve it (although anything is a start).

Could you give us a code fragments of the relevant parts?

a) the code fragment that calls zsql (assuming thats what is being called)
b) a print out of the "request" (just before the zsql is called unless 
you pass zsql params directly)
c) your zsql that is not adding records

You might as well also add your OS version and type, Zope version and 
which data adapter you are using. 

ps:  if any of your methods are *external* then changes will not show up 
in some cases (debugging on/off?) unless you update its external python 
"link" as well.
