Error while compiling a function

Question

Hi,
I wanted to write a function that would give me the database name.
+
CREATE OR REPLACE
FUNCTION getdbname
RETURN VARCHAR2
IS
X VARCHAR2(10);
BEGIN
SELECT NAME INTO X FROM V$DATABASE;
RETURN x;
END;
+
but it gave me the following error
+
5/30 PL/SQL: ORA-00942: table or view does not exist
5/5 PL/SQL: SQL Statement ignored
+
if I wrote the anonymous procedure:
+
declare
X VARCHAR2(10);
BEGIN
SELECT NAME INTO X FROM V$DATABASE;
dbms_output.put_line(x);
END;
+
this gives me the output:
where am I going wrong to write the function?
thanks,
sam

privileges acquired via ROLE do NOT apply within named PL/SQL procedures
Direct GRANT is required
GRANT SELECT ON V_$DATABASE TO SCOTT;
