under-transaction ?

[CM]

Hello,

Is it possible to create a transaction in a transaction?

BEGIN T1

INSERT into t1 values(2);

BEGIN T2

INSERT into t1 values(3);

ROLLBACK T2

COMMIT T1

I will have liked that the "ROLLBACK" of the T2 transaction
does not disturb the "INSERT" made in the principal transaction.
If that exists, which are commands SQL for Oracle 9i? Thank you very much.
(And excuse me for my imperfect English)

This (oracle) is NOT sql server.

And yes - using autonomous transactions it would be possible.
And... if you want this for logging purposes, look at the monitor
sub command of the alter table SQL command.
The SQL Reference Guide can be found online at http://docs.oracle.com

And last but not least - this should have been posted in c.d.o.database.

In 1997 the attendees votes to replace this comp.database.o racle (c.d.o)
newsgroup with a set of newsgroups - c.d.o.server, c.d.o.tools,
c.d.o.marketpla ce and c.d.o.misc As a result, some ISPs do not carry
c.d.o but do carry the lower ones, and you run the risk of not getting
the visibility you want.

When we remember, we try to discourage using this one.
