Get the difference between two dates both In Months and days in sql

Question

I need to get the difference between two dates say if the difference is 84 days, I should probably have output as 2 months and 14 days, the code I have just gives the totals

Answer 1

The solution I post will consider a month with 30 days

  select CONCAT (CONCAT (num_months,' MONTHS '), CONCAT ((days-(num_months)*30),' DAYS '))
  from ( 
  SELECT floor(Months_between(To_date('20120325', 'YYYYMMDD'),
   To_date('20120101', 'YYYYMMDD')))
   num_months,
   ( To_date('20120325', 'YYYYMMDD') - To_date('20120101', 'YYYYMMDD') )
   days
  FROM   dual);
