Answer 1

感謝大家的response.I找到了答案，雖然。

create table Test_table 
(
Date_Of_Birth datetime, 
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'), 
('2015-3-26 00:00:00','2017-7-3 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 
) 
select Date_Of_Birth,received_Date,cast(Years as varchar)+' Years 
'+cast(Months as varchar)+' Months 
'+cast(datediff(day,dateadd(month,12*Years+Months,Date_Of_Birth), 
received_Date) as varchar)+' Days ' as Age from cte_months

更新版本：

DECLARE @today DATETIME; 
SET @today = GETDATE(); 
DECLARE @dates TABLE (DOB DATETIME); 
INSERT INTO @dates 
VALUES ('2016-11-02'), 
     ('2015-03-26'), 
     ('2010-11-20'), 
     ('2017-06-17'); 
SELECT DOB , 
     DATEDIFF(YEAR, DOB, @today) AS [Age] , 
     DATEDIFF(YEAR, DOB, @today) 
     - CASE WHEN MONTH(DOB) > MONTH(@today) 
        OR MONTH(DOB) = MONTH(@today) 
        AND DAY(DOB) > DAY(@today) THEN 1 
       ELSE 0 
      END AS Years , 
     DATEDIFF(MONTH, 
       DATEADD(YEAR, 
         DATEDIFF(YEAR, DOB, @today) 
         - CASE WHEN MONTH(DOB) > MONTH(@today) 
            OR MONTH(DOB) = MONTH(@today) 
            AND DAY(DOB) > DAY(@today) THEN 1 
           ELSE 0 
          END, DOB), @today) 
     - CASE WHEN DAY(DOB) > DAY(@today) THEN 1 
       ELSE 0 
      END AS Months , 
     DATEDIFF(DAY, 
       DATEADD(MONTH,

FROM @dates;
