v$session in procedure

Does anyone tell me How to cursor with v$session in a procedure?

I try

CURSOR CR_SESSION IS
select sid, serial# from sys.v$session where type='USER';

or
CURSOR CR_SESSION IS
select sid, serial# from sys.v_$session where type='USER';

or
CURSOR CR_SESSION IS
select sid, serial# from v$session where type='USER';

all get error:
PLS-00201: identifier 'SYS.V$SESSION' must be declared

thanks

Have you granted permission explictly to your user?

Code:

---

SQL> declare
  2    cnt number;
  3  begin
  4  select count(*) into cnt from v$session;
  5  end;
  6  /
select count(*) into cnt from v$session;
                              *
ERROR at line 4:
ORA-06550: line 4, column 31:
PLS-00201: identifier 'SYS.V_$SESSION' must be declared
ORA-06550: line 4, column 1:
PL/SQL: SQL Statement ignored


SQL> connect sys
Enter password: **********
Connected.
SQL> grant select on v_$session to jeffh;

Grant succeeded.

SQL> connect jeffh/jeffh
Connected.
SQL> declare
  2    cnt number;
  3  begin
  4  select count(*) into cnt from v$session;
  5  end;
  6  /

you have to grant select privs on v$session directly to user

connect as sys

grant select on v_$session to user

surely any user with resource role should be able to see v$session?

Permissions from roles can not be seen in a pl/sql procedure.

thanks, after grant select it works
