Flahback table to before an update

Question

db is 10.2.0.4
os is AIX 5L
Hi.
I have run an update on a table.
I can see the update on the v$sqlarea view.
What is the best way to flahback the table to just before this update?
I can see a first_load_time column in the v$sqlarea view.
Should I flashback to this time as timestamp?

Answer 1

Something like this ?
SCOTT@orcl> create table test(a number(2));
Table created.
SCOTT@orcl> insert into test values(5);
1 row created.
SCOTT@orcl> insert into test values(10);
1 row created.
SCOTT@orcl> insert into test values(15);
1 row created.
SCOTT@orcl> commit;
Commit complete.
SCOTT@orcl> select to_char(sysdate,'dd-mm-yy hh24:mi:ss') time from dual;
TIME
29-06-10 10:26:18
SCOTT@orcl> insert into test values(20);
1 row created.
SCOTT@orcl> insert into test values(25);
1 row created.
SCOTT@orcl> commit;
Commit complete.
SCOTT@orcl> select to_char(sysdate,'dd-mm-yy hh24:mi:ss') time from dual;
TIME
29-06-10 10:26:37
SCOTT@orcl> select * from test
  2  as of timestamp to_timestamp('29-06-10 10:26:18','dd-mm-yy hh24:mi:ss');
         A
         5
        10
        15
SCOTT@orcl> select * from test;
         A
         5
        10
        15
        20
        25
SCOTT@orcl>But, it is not necessary that it will work after 1min, 1hr or 1 day, because it depends on how much undo i am having and workload on database; but yes we can create another table; even after commit, with the above; as of timestamp clause; within a reasonable time period something like :
create newtable as select * from test
as of timestamp to_timestamp('29-06-10 10:26:18','dd-mm-yy hh24:mi:ss');
