Yes, convert all columns to varchar2 or raw then you can insert what you want.

If the requirement st... sil... inappropriate it may be more useful and efficient to report the fact instead of trying to fit it.

Actually, there's a relatively simple way to insert a DATE into a NUMBER column - a Julian date!
SQL> create table test (date_n number);

Table created.

SQL> insert into test (date_n)
  2    select to_number(to_char(sysdate, 'J'))
  3    from dual;

1 row created.

SQL> select date_n,
  2         to_char(to_date(date_n, 'J'), 'dd.mm.yyyy') date_d
  3  from test;

    DATE_N DATE_D
---------- ----------
   2454679 31.07.2008

SQL>

The only reason you would want to store a zero in a date field is to flag it for special processing. You can do this two ways. Store a special date into the column

my_date := to_date('01/01/0001','mm/dd/yyyy')

which would be findable via an index or use a null, which would not be findable via an index.


my_date := null;


a number is impossible and makes no sense.

...or use a third and superior way: use a flag column to flag special occurrences and use the date column for what it is meant to store.
Using 'special' values will lead to trouble, sooner or later.
