length of a long raw column

Hi Oracle PL/SQL experts,

how do i examine the length of a long raw column with PL/SQL and sqlplus?

Example:
create table foobar (id number, foo long raw); insert into foobar values (1, '010101');

select length(foo) from foobar

              *
ERROR at line 1:
ORA-00932: inconsistent datatypes

Can Oracle PL/SQL experts there help me?

Thanks
