If I understood you're telling me that begin and commit statements are "redundant".

Yes, exactly: they are issued by Zope at the boundaries of a transaction.

Sometimes conflicts are not correctly managed by ZTM (no rollbacks in db)

sql server with ZODBC

Sorry, I don't have direct experience with it. However, IIRC, ZODBC is quite old and could have some problems. I would suggest you to invest a few Euros in mxODBC: I've never tried it but Egenix has a good record of producing good products. Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/
