[Zope-DB] Transaction questions

[Jose Gerardo Amaya Giron]

I want to use MS SQL Server transactions, do I need to include them in
my SQL Methods or Zope is doing this already when I call them.
I make some inserts to several tables(separate methods) and when one of
them fail it does not roll back to the initial state.
What do I need to do.

thanks in advance
