Hi John Dunn,
My answer is never commit, Oracle will rollback.
Are you consider auto commit an implicitly commitment?

Under what circumstances is a COMMIT done implicitly?
If I call
if I recall correctly, implicit commits are done
a) on a clean exit from sqlplus
b) on a clean exit from a stored program
c) if you do a DDL statement after the DML statement
but this is from memory and without checking manuals.

John,
there is no such thing as an implicit commit within Oracle.
the only implicit commit that I know of is during a sqlplus session when you
exit the program. even this is settable by a sqlplus option.
distributed transactions that are controlled by a transaction coordinator

Tom,
Oracle issues an implicit commit any time DDL is performed or when a
quit/exit is issued (Complete Ref p285) or after a set number of commands by
using a set autocommit # (Complete Ref 283). With the latter is arguably
not truly an implicit commit, as you do set it, DDL most certainly is.
Tom,
I must respectfully disagree. Explicit = a COMMIT or ROLLBACK is
explicitly issued by the user/program. Implicit = a COMMIT or ROLLBACK is
performed as the result of an action and not issued by the user/program.
The SQL*Plus options AUTOCOMMIT and COPYCOMMIT do not control

Dan,
I agree with you and I think I said the same thing - though not as lengthy!
:)
As you said, the Sql*Plus AutoCommit option controls issuing a commit upon
exiting the program.
As I said in a prior mail, I did not mention DDL forcing an implicit commit
as the question pertained to INSERT
AUTOCOMMIT controls COMMITs after execution of individual DML statements,
not upon EXITing SQL*Plus.
The point I want to make is that IMPLICIT COMMITs ROLLBACKs do occur. I
have encountered the following scenario more than once...
'Oracle is not saving changes' is the complaint from the users.
