Result of subtracting 2 dates

Dear List,
I want to convert the resultant numeric value of the subtracting 2 date columns in a table.

Eg:
select sysdate-joindate from emp

will result in a numeric value. I want this numeric value to be displayed as a date value.

Any clues

TIA

Can you provide an example?

What is the result of April 10, 2001 - April 8, 2001 in a date format?

The result of subtracting 2 dates is the number of days.


1 select to_date('22/10/2001','dd/mm/yyyy') -
2* to_date('20/10/2001','dd/mm/yyyy') result from dual
SQL> /

RESULT
---------
2

Yor question is how can I display the number 2 as a date ?
It does not make sense , does it ?

I agree that the answer is 2.

or you really mean subtract two dates instead in number of days you want it in months and days
