Oracle: How to find out if there is a transaction pending?

Question

I\'m looking for a way to find out if there are uncommited INSERT, UPDATE or DELETE statements in the current session. One way would be to check v$lock with the current sid,

Answer 1

you can check if your session has a row in V$TRANSACTION (obviously that requires read privilege on this view):

SQL> SELECT COUNT(*)
       FROM v$transaction t, v$session s, v$mystat m
      WHERE t.ses_addr = s.saddr
        AND s.sid = m.sid
        AND ROWNUM = 1;

  COUNT(*)
----------
         0

SQL> insert into a values (1);

1 row inserted

SQL> SELECT COUNT(*)
       FROM v$transaction t, v$session s, v$mystat m
      WHERE t.ses_addr = s.saddr
        AND s.sid = m.sid
        AND ROWNUM = 1;

  COUNT(*)
----------
         1

SQL> commit;

Commit complete

SQL> SELECT COUNT(*)
       FROM v$transaction t, v$session s, v$mystat m
      WHERE t.ses_addr = s.saddr
        AND s.sid = m.sid
        AND ROWNUM = 1;

  COUNT(*)
----------
         0
