I'm a beginner with Zope&DTML, and currently I'm trying to make a kind of dynamic interactive DB,using Zope. However I faced some basic problems right at the beginning. Maybe somebody could help me..?

Sure!

Do you know, maybe why this type of quiry, when being tested, always gives me a message that "Python performed an illigal operation and will be shut down" ?? [snip SQL query]

Hm, Python shutting down because of illegal operations hasn't ever happened to me. Weird. Perhaps the DigiCool gurus know more.. I think you imply later in your post that you're using Access.. I've used Access with Z ODBC database adapter, and it works fine for me. Any error messages I got were self induced. :)

Can it be that I define arguments in the ZSQL method-form in a wrong way?? I separated them with a space like this "Arguments: age place".

That is the right way. I use types for the arguments; I'm not sure how that influences things. Like this: arg1:string arg2:int arg3:required

Is it possible somehow to ADD or MODIFY data in a DB (which is kept in Access) through a Zope web-page. And if yes - what could be an implementation template?

Yes, that's possible, I'm doing this all the time. Just use a SQL INSERT or UPDATE statement instead of SELECT in your SQL method and it should work. The basic strategy I use for insertion is this: A web page with a form where I enter the data for the fields of a new record. A Z SQL method with an insert statement. A 'report page' which: * Is called by the form on the entry page (i.e. <form action="report_page">) * calls the Z SQL method, passing on the inputted data in REQUEST, like this: <!--#call "some_sql_method(REQUEST)"--> * After that, reports that the operation was successful: <p>Yeah, you did it!</p> And some button to go back to wherever you came from or have to go (in my case the main list of all records in a database table -- displayed in a HTML table). I hope this helps. If you want more details feel free to ask. :) Regards and good luck, Martijn
