When I write out a DDL - no PK:FK constraints

Question

Hi;
When I use Application to write out a .sql file for a schema, it does not write out the PK:FK constraints. Any idea how to get this?
thanks - dave

select
p.constraint_name "Primary or Unique Key", p.owner "PKEY_OWNER", p.table_name "PKEY_TABLENAME"
,f.constraint_name "FKEY_NAME", f.owner "FKEY_OWNER", f.table_name "FKEY_TABLENAME"
from user_constraints p, user_constraints f
where p.constraint_type in ('U','P')
and f.constraint_type(+) = 'R'
and f.r_owner(+) = p.owner
and f.r_constraint_name(+) = p.constraint_name
Or
select
p.constraint_name "Primary or Unique Key", p.owner "PKEY_OWNER", p.table_name "PKEY_TABLENAME"
,f.constraint_name "FKEY_NAME", f.owner "FKEY_OWNER", f.table_name "FKEY_TABLENAME"
from user_constraints p left outer join user_constraints f
on f.r_owner = p.owner
and f.r_constraint_name = p.constraint_name
where p.constraint_type in ('U','P')
and (f.constraint_type = 'R' or f.constraint_name is null)
;
