T-SQL: calculate age then add character to result

Question

Been stuck on this one for a while now. Let\'s say I have a Client table like the one here:

Name   BirthDayNum   BirthMonthNum   BirthYearNum
--         


        

Answer 1

If you are on 2008 or lesser and can't use datefromparts...

declare @table table ([Name] varchar(4), BirthDayNum int, BirthMonthNum int, BirthYearNum int)
insert into @table
values
('John',23,12,1965),
('Jane',4,9,1975),
('Day',30,3,1990)

;with cte as(
    select
        [Name],
        cast(BirthYearNum as varchar(4)) + '/' + cast(BirthMonthNum as varchar(2)) + '/' + cast(BirthDayNum as varchar(2)) as DOB
    from 
        @table)

select 
     [Name]
     ,DOB
     ,datediff(year,DOB,GETDATE()) as Years
     ,datediff(month,DOB,GETDATE()) %12 as Months
     ,rtrim(cast(datediff(year,DOB,GETDATE()) as char(2))) + 'y ' + rtrim(cast(datediff(month,DOB,GETDATE()) %12 as char(2))) + 'm' as  Age 
from cte
