ORA-00911 in Dynamic SQL

I am trying to create a stored procedure with dynamic sql referencing the V$SESSION table (view). I need to use this dynamically, because the procedure will not compile if the user does not have access to this table. The $ is what's causing the trouble:

declare v_sql varchar2(4000);
begin
v_sql := 'select * from v$session;';
execute immediate (v_sql);
end;
/

I've tried \ and double quotes, but they don't work. Any clues?

THANK YOU!!!! trace Received on Thu Apr 08 2004 - 22:35:36 CEST
