[Zope] sql-statements in DTML-Methods....

Hi. This is one of the first times I'm working with Zope and databases. Until now - if I wanted to work with a databse, i always created a Z SQL method that I called from my DTML-method via <dtml-call "add_item(param1 = ..., param2 = ..., param3 = ..., ..."> (for example) or <dtml-in get_items> ... </dtml-in> (for example) In the Z SQL method 'add_item' or 'get_items', my SQL statement are defined. My question is now: Do I have to define one Z SQL Method for every SQL statement I want to perform on my database or is it possible to define SQL-statements and database requests in my DTML-method? Am I missing something? Any idea? Thanks a lot. Regards, Marc mailto:lutschi72@gmx.net
