Clob help

Question

I am trying to obtain the clob from a table. The examples I am seeing just are not making it clear.
create table myclob (key number,c clob);if I want to obtain a clob from that table what do I need to do.
Seems like this should work
declare
cursor cur is select c from myclob where key = 1;
v_c clob;
begin
open cur;
fetch cur into v_c;
close cur;
end;
/the error which is returned is:
ORA-00932: inconsistent datatypes: expected NUMBER got LONG
seems like it should work but is not .. what do I need to do?
Thanks
Ox
