The original plan was to simplify the DB-API by reducing the number of possible paramstyles, but you're probably right: it's better to just require support for a few and leave other paramstyles as option to the module authors, if they choose to support more than just the two basic ones. That way people writing new code can focus on just those two styles, while existing applications can continue to work with the optional ones. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, May 17 2013) >>> Python Projects, Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope/Plone.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ 2013-05-07: Released mxODBC Zope DA 2.1.2 ... http://egenix.com/go46 2013-05-06: Released mxODBC 3.2.3 ... http://egenix.com/go45 ::::: Try our mxODBC.Connect Python Database Interface for free ! :::::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
