Thank you very much, it worked!!
Just FYI, I tried this way, it worked on 10gR2 (Linux), but gave error on 9iR2 (HP-UX):
Oracle9i Enterprise Edition Release 184.108.40.206.0 - 64bit Production With the Partitioning, OLAP and Oracle Data Mining options JServer Release 220.127.116.11.0 - Production
(select paddr from v$session *
ERROR at line 3:
ORA-01427: single-row subquery returns more than one row
SQL> !cat getspid1.sql
select spid from v$process
(select paddr from v$session where audsid = userenv( 'sessionid' )) ;
I suspect most probably a bug which I did not patch. Just to share, don't have to reply :-).
