Thanks for the response, Dieter. For consistency within Zope, an integer result could still be repackaged as a sequence result. For now I can do what I wanted to by: select count(food) from penguins where food='Henri Bergson' (thus getting the number of records about to be affected by a delete as a sequence result) before running: delete from penguins where food='Henri Bergson' Cheers, Chris On Tue, 28 Nov 2000, Dieter Maurer wrote:

In psql a delete command returns a count of the number of rows deleted. Is this returned result available to a ZSQL method using PoPy or PyGreSQL? I think, Zope should pass integer results from SQL commands. But I fear, it does not.

When I looked at the code (quite some time ago), I had the impression, that Zope does only pass sequence results. Integer results are translated into 'None'.
