Hi, if your user has enough privileges you can use:

SELECT SID
  FROM v$session
 WHERE username = user;

Note: this will return all session IDs for the current user.

Hi hayrabedian,

your solution doesn't work for me because there can be multiple sessions with the same username.

thanks though for your quick reply,

Yes, you are right. You need to use:

SELECT sid FROM V$SESSION WHERE audsid = USERENV('SESSIONID');

If user does not have the priviledge, you can grant the rights when connected as SYS user:

GRANT SELECT ON V_$SESSION TO user;

Hi,

yes the solution from Ali is the right one :)
Just one detail:

You can use just:
SELECT USERENV('SESSIONID') FROM DUAL;

And no privileges are needed.

Hi,

Ali is right again:) I don't know why the "Auditing session ID" is returned by the USERENV('SESSIONID'), but we have to live with that.

Best regards,
Eddie
