SQL syntax Problem

Question

let's say i want to get exactly the total service for an employee (how many years, how many months & how many days):
the Appointment date is : 11/17/1992
the Termination date is : 03/06/2001
by using months_between it will be like this:
select month_between(to_date('03/06/2001','MM/DD/YYYY'),to_date('11/17/1992','MM/DD/YYYY')) from dual;
it will give exactly : 99.6451613 ,then
we will divide it by 12 to get the years ,then we can truncate it to get the hole figure of the years, it will give exactly 8 years , my problem starts from here : how to get the months and the days?!!!!

Answer 1

Try this:
select trunc(m/12) "Years", trunc(m-trunc(m/12)*12) "Months", (m-trunc(m))*31 "Days" from (select months_between(to_date('03/06/2001','MM/DD/YYYY'),to_date('11/17/1992','MM/DD/YYYY')) as m from dual where rownum=1)
I did not check it (too many days to count :), but the results are reasonable.
