It is "funny behaviour", because I expect those operations of the transaction, which executed successfully, to be performed in an atomic way. It is obvious that I cannot expect an operation which reported an error to have any effect. "Atomic" means that all operations (whether successful or not) will be carried out all together or none of them - but only the successful ones will have had an effect. Again: Why not make a difference between "commit" and "rollback" in a transaction in this case? Why not let the user decide which parts should be commited? The practical reason is that programming would become a lot more convenient. (if there is a practical reason it does not necessarily need a technical reason, I believe.)
