How to calculate age in Year,Month and Days from date of birth in MySql.

i used an existing query to get the result,like

SQL

select TIMESTAMPDIFF( YEAR, dojDate,now()) as years
    , TIMESTAMPDIFF( MONTH, dojDate,now()) % 12 as months
    , FLOOR( TIMESTAMPDIFF( DAY, dojDate,now()) % 30.4375 ) as days

but the issue is that,
Suppose

DOJ : '2010-01-01'
NOW : '2011-01-02'
O/P : 1 Year ,0 Month, 0 Days
Correct. 

DOJ : '2010-01-01'
NOW : '2011-01-01'
O/P : 1 Year ,0 Month, 30 Days
Actually this should return 0 Year, 11 Month, 30 Days

How to get this??

Solution 2

use this query :

SQL

select extract(year from from_days(days)) - 1600 as years
     , extract(month from from_days(days)) - 1 as months
     , extract(day from from_days(days)) - 1 as days
  from ( select to_days(now()) - to_days(a.dojDate) +
                to_days(str_to_date('1600-01-01', '%Y-%m-%d')) as days
           from sampletable a ) as b
