Thank you very much, it worked!!
Just FYI, I tried this way, it worked on 10gR2 (Linux), but gave error
on 9iR2 (HP-UX):
Connected to:
Oracle9i Enterprise Edition Release 9.2.0.1.0 - 64bit Production
With the Partitioning, OLAP and Oracle Data Mining options
JServer Release 9.2.0.1.0 - Production
SQL> @getspid1
(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
where addr=
(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 :-).
