I was just catching up on some reading and after seeing some newbie posts, I thought to mention this. A while ago I spent some time writing a how-to on Zope and SQL integration for newbies. I found this part of Zope (sticking zpt, script and zsql components together after understanding what each did) to be quite difficult as a newbie. http://zope.org/Members/nickbower/DataAppsHowTo Just in case it helps some people out there.

Hi,

I'm creating a form which can be used to build queries by the user. It's not a general purpose query designer, but it involves a few tables and I'll have to create several quite different queries.

I don't want to go through the trouble of manually preparing all the possible queries (ZSQL methods) in antecipation. I would like the form to call a PythonScript which will build the SQL statement and then _somehow_ run it and _somehow_ return a second web page, a ZPT page which can use the results sequence to show it to the user.

So, two questions:

- how can I execute the SQL statement to get a sequence?

- how can I send the second page built with the results from the PythonScript to the user? (I believe I can use 'options' in zpt to receive parameters from a Script, but I'm not sure this is the best option for this case).

Another possibility would be to pass the SQL statement to the second ZPT page and run it there _somehow_. Hmm, using 'options' I could pass the SQL statement and in the ZPT page I can call a python script which executes the SQL statement and returns a sequence. But how can I have a Script executing a SQL statement?

TIA, Fernando
