Sql Scripts for knowing the transaction status

select * from v$transaction;

--All tranasactions + sid and username
select s.sid,s.username, t.start_time, t.used_ublk, t.used_urec
from v$transaction t, v$session s
where t.ses_addr=s.saddr;

--All tranasactions + sid and username + first 64 bytes of SQL
select s.sid,s.username, t.start_time, t.used_ublk, t.used_urec,sql.sql_text
from v$transaction t, v$session s, v$sql sql
where t.ses_addr=s.saddr
and s.sql_address=sql.address and s.sql_hash_value=sql.hash_value;

Yes, well, just that the 3rd select is wrong.

v$session only tracks the current and the previous executed sql statement and since 1 transaction <> 1 sql statement, the sql statement you will see, does not necessarily have anything in common with the transaction, besides of the fact, that it is executed within the same session, before the transaction initiated by this session, at some point in the past, was committed/rolled back.

A fascinating discussion is definitely worth comment. I do
believe that you need to write more on this issue, it may not
be a taboo subject but typically folks don't talk about these topics. To the next! All the best!!
