有没有办法根据今天的日期和他们的生日来计算某人的年龄,然后以下列方式显示:
If a user is less than (<) 1 year old THEN show their age in MM & days.
Example: 10 months & 2 days old
If a user is more than 1 year old AND less than 6 years old THEN show their age in YY & MM & days.
Example: 5 years & 3 months & 10 days old
If a user is more than 6 years old THEN display their age in YY.
Example: 12 years

这基本上就是你要找的东西:
DECLARE @date1 DATETIME
, @date2 DATETIME;
SELECT @date1 = '1/1/2008'
, @date2 = GETDATE();
SELECT CASE
WHEN DATEDIFF(YEAR, @date1, @date2) < 1 THEN CAST(DATEDIFF(mm, @date1, @date2) AS VARCHAR)+' Months & '+CAST(DATEDIFF(dd, DATEADD(mm, DATEDIFF(mm, @date1, @date2), @date1), @date2) AS VARCHAR)+' Days'
WHEN DATEDIFF(YEAR, @date1, @date2) BETWEEN 1 AND 5 THEN CAST(DATEDIFF(mm, @date1, @date2) / 12 AS VARCHAR)+' Years & '+CAST(DATEDIFF(mm, @date1, @date2) % 12 AS VARCHAR)+' Months'
WHEN DATEDIFF(YEAR, @date1, @date2) >= 6 THEN CAST(DATEDIFF(YEAR, @date1, @date2) AS VARCHAR)+' Years'
END;
当用户小于(&lt;)1岁时的结果然后显示他们的年龄在MM&amp;天:
当用户超过1岁且小于6岁时的结果然后显示他们的年龄在YY&amp; MM&amp;天:
当用户超过6岁时的结果然后在YY中显示他们的年龄:

来自上一个问题 How to calculate age in T-SQL with years, months, and days
你可以做这样的程序
CREATE procedure [dbo].[proc_datediff]
(
@date datetime
)
as
begin
DECLARE @diff varchar(70)
DECLARE @tmpdate datetime, @years int, @months int, @days int
SELECT @tmpdate = @date
SELECT @years = DATEDIFF(yy, @tmpdate, GETDATE()) - CASE WHEN
(MONTH(@date) > MONTH(GETDATE())) OR (MONTH(@date) =
MONTH(GETDATE()) AND DAY(@date) > DAY(GETDATE())) THEN 1 ELSE 0 END
SELECT @tmpdate = DATEADD(yy, @years, @tmpdate)
SELECT @months = DATEDIFF(m, @tmpdate, GETDATE()) - CASE WHEN
DAY(@date) > DAY(GETDATE()) THEN 1 ELSE 0 END
SELECT @tmpdate = DATEADD(m, @months, @tmpdate)
SELECT @days = DATEDIFF(d, @tmpdate, GETDATE())
select @diff=
case
when @years < 1 then
concat( @months,' Months ',@days,' days ' )
when @years >=1 and @years < 6
then
concat(@years,' year ', @months,' Months ',@days,' days ' )
when @years >= 6 then
concat( @years,' years ' )
end;
select @diff
end
execute proc_datediff '1/1/2016'
go

可能不是最有效的解决方法,但这是我如何做到的:
我必须首先获得今天的日期和人的出生日期之间的日期差异。通过将它与ABS()和剩余(%)函数相结合,我用它来获得年,月,日等。
declare @year int = 365
declare @month int = 30
declare @sixYears int = 2190
select
--CAST(DATEDIFF(mm, a.BirthDateTime, getdate()) AS VARCHAR) as GetMonth,
--CAST(DATEDIFF(dd, DATEADD(mm, DATEDIFF(mm, a.BirthDateTime, getdate()), a.BirthDateTime), getdate()) AS VARCHAR) as GetDays,
CASE
WHEN
DATEDIFF(dd,a.BirthDateTime,getdate()) < @year
THEN
cast((DATEDIFF(dd,a.BirthDateTime,getdate()) / (@month)) as varchar) +' Months & ' +
CAST(ABS(DATEDIFF(dd, DATEADD(mm, DATEDIFF(mm, a.BirthDateTime, getdate()), a.BirthDateTime), getdate())) AS VARCHAR)
+ ' Days'
WHEN
DATEDIFF(dd,a.BirthDateTime,getdate()) between @year and @sixYears
THEN
cast((DATEDIFF(dd,a.BirthDateTime,getdate()) / (@year)) as varchar) +' Years & ' +
CAST((DATEDIFF(mm, a.BirthDateTime, getdate()) % (12)) AS VARCHAR) + ' Months'
WHEN DATEDIFF(dd,a.BirthDateTime,getdate()) > @sixYears
THEN cast(a.Age as varchar) + ' Years'
end as FinalAGE,
