Quote:

A constraint violation will
force an automatic rollback of the entire
statement that hit the problem, not just
the single action within the statement,
and not the entire transaction.

i don't quite get it. The part on 'and not the entire transaction'.

The first part have already mention it will rollback the ENTIRE statement.

I recognize this as a quote from my book. I asked before, do you have a proper copy of it, or only a copy of it on CD?

Transaction != statement.

Maybe you should firstly get familiar with basic database terms. They are also described in Concepts book, available with other Oracle documentation e.g. online on http://tahiti.oracle.com/

For 11gR2, transactions are described here: http://download.oracle.com/docs/cd/E11882_01/server.112/e25789/transact.htm#i6564
