pl/sql code hanging

Hi,

Not sure if I wrote something wrong in this code - this is hanging

  1  declare

  2      id1 t4.id%TYPE;

  3      name1 t4.name%TYPE;

  4  c1 sys_refcursor;

  5  begin

  6     open  c1 for select t4.id,name from t4,t where t4.id=t.id;

  7      loop

  8      fetch c1 into id1,name1;

  9  dbms_output.put_line(name1||'and'||id1);

10      end loop;

11*   end;

SQL> /

SQL> select count(*) from t4,t where t4.id=t.id;

  COUNT(*)

----------

       260

Best regards,
