In my small application i use only one connection (per client). I manage 
the customer orders of a food stand. The orders have header and lines. 
In that case i do a commit only after insert/update of the 2 table's 
records so i can not use an autocommit connection.

But what i wrote before and your suggestion are just fine for my needs, 
thanks
