received_Date datetime, 
) 

insert into Test_table values 
('2016-11-02 00:00:00','2017-7-15 00:00:00'), 
('2015-7-17 00:00:00','2017-7-13 00:00:00'),

GO 

;with cte_years as 
(
select case when 
DATEADD(year,DATEDIFF(Year,Date_Of_Birth,received_Date),Date_Of_Birth)> 
received_Date then DATEDIFF(Year,Date_Of_Birth,received_Date)-1 
    else DATEDIFF(Year,Date_Of_Birth,received_Date) end as Years, 
Date_Of_Birth, 
received_Date 
from Test_Table 
), 
cte_months as 
(
select 
Years, 
case when 
    DATEADD(month,DATEDIFF(month,Date_Of_Birth,received_Date),Date_Of_Birth)> 
    received_Date 
    then DATEDIFF(month,Date_Of_Birth,received_Date)-1-Years*12 
    else DATEDIFF(month,Date_Of_Birth,received_Date)-Years*12 end as 
Months,Date_Of_Birth,received_Date 
from cte_years
