Create type with refering the data type

Question

Is it possible to refer the column datatype of a type to a table.column datatype?
create or replace type OT_SAMPLE1
as object
( codeid       table.codeid%type
, sdate         table.sdate%type
, edate        table.edate%type
/or is there a workaround? any ideas?

Answer 1

Object types live in the same "world" as tablesNot in all respects though: Length of 32767 "should" only work in plsql:
SQL> create or replace type ot_sample1 as object
   (codeid varchar2 (32676),
   codeid2 raw(32767));
Type created.
SQL> declare
   o   ot_sample1 := ot_sample1 (lpad ('x', 32676, 'x'), lpad ('0', 32676, '0'));
begin
   dbms_output.put_line ('Length: ' || length (o.codeid));
end;
Length: 32676
PL/SQL procedure successfully completed.but of course:
SQL> select length (t.o.codeid), length (t.o.codeid2)
  from (select ot_sample1 (lpad ('x', 32676, 'x'), lpad ('0', 32676, '0')) o from dual) t
LENGTH(T.O.CODEID) LENGTH(T.O.CODEID2)
              4000                4000
