I tend to avoid deprecated functions/methods - I would need another method sooner or later anyway.

That works, thank you. I will use the cursor.description attribute immediately after executing a query, so it will contain the correct field descriptions whenever I need them. The rest of my program uses the type attribute to decide which fields are present and which are not.

All this is part of a port from Perl to Python - I will publish a log of everything I encountered in a couple of weeks.
