[Zope-DB] ZSQL Question - Insert multiple rows in one statement?

[Sascha Gottfried]

Hi Mark,

it is best to do the looping in python. consider the python script as 
the proper place to process the form values taken from the request 
variable. No problem to invoke multiple zsql method calls from within 
this script. I even remember that all invoked zsql methods in one 
requests belong to a transaction. If one fails, a rollback is done. Your 
ZSQL connection has to be configured properly to use transactions and 
your server has to support them as well.

Just in case you do not already found this - latest zope book and the 
chapter about SQL connectivity
