RE: [Zope] Newbie questions: Calling PageTemplates from Python, a nd getting meta-info on ZSQL method results
Hi, This page contains some very useful info. I have a question now about the contents of the data_dictionary in the resultset: Is there any indication whether a field is regarded a primary key by the database? Is there a non-database-specific way to find this out? I would find it quite useful to know this info. With regards, --Tim
