我试图延长Dane的答案，但结果有点问题。

DECLARE @dateFrom DATETIME
DECLARE @dateTo DATETIME
DECLARE @tmpdate DATETIME 
DECLARE @years INT
DECLARE @months INT
DECLARE @days INT
DECLARE @hours INT
DECLARE @minutes INT
DECLARE @seconds INT
DECLARE @milliseconds INT

SELECT @dateFrom = '2011-01-01 11:24:38:100'
SELECT @dateTo = '2012-01-01 11:24:38:110'

SELECT @tmpdate = @dateFrom

SELECT @years = DATEDIFF(yy, @tmpdate, @dateTo) 
        - CASE WHEN (MONTH(@dateFrom) > MONTH(@dateTo)) OR (MONTH(@dateFrom) =  MONTH(@dateTo) AND DAY(@dateFrom) > DAY(@dateTo))
            THEN 1
            ELSE 0
        END
SELECT @tmpdate         = DATEADD(yy, @years, @tmpdate)
SELECT @months          = DATEDIFF(mm, @tmpdate, @dateTo) - CASE WHEN   DAY(@dateFrom) > DAY(@dateTo) THEN 1 ELSE 0 END
SELECT @tmpdate         = DATEADD(mm, @months, @tmpdate)
SELECT @days            = DATEDIFF(dd, @tmpdate, @dateTo)
SELECT @tmpdate         = DATEADD(dd, @days, @tmpdate)
SELECT @hours           = DATEDIFF(hh, @tmpdate, @dateTo)
SELECT @tmpdate         = DATEADD(hh, @hours, @tmpdate)
SELECT @minutes         = DATEDIFF(mi, @tmpdate, @dateTo)
SELECT @tmpdate         = DATEADD(mi, @minutes, @tmpdate)
SELECT @seconds         = DATEDIFF(ss, @tmpdate, @dateTo)
SELECT @tmpdate         = DATEADD(ss, @seconds, @tmpdate)
SELECT @milliseconds    = DATEDIFF(ms, @tmpdate, @dateTo)

SELECT
    @years AS [years]
    , @months AS [months]
    , @days AS [days]
    , @hours AS [hours]
    , @minutes AS [minutes]
    , @seconds AS [seconds]
    , @milliseconds AS [milliseconds]

结果是：

years   months  days    hours   minutes seconds milliseconds
1       0       0       0       0       0       10

但是当我跑步时：

SELECT @dateFrom = '2011-01-02 11:24:38:110'
SELECT @dateTo = '2012-01-01 10:23:37:100'

结果是：

years   months  days    hours   minutes seconds milliseconds
0       11      30      -1      -1      -1      -10

帮助将不胜感激！

Answer 1

答案是正确的，但它显示为负值。您需要使用abs来返回正值

 SELECT
 @years AS [years]
, abs(@months) AS [months]
, abs(@days) AS [days]
, abs(@hours) AS [hours]
, abs(@minutes) AS [minutes]
, abs(@seconds) AS [seconds]
, abs(@milliseconds) AS [milliseconds]

Answer 2

你得到这些负值，因为@dateFrom中的日期晚于@dateTo中的日期，我认为你可以做的最好的事情是在流程开始之前交换这些值，这样你就不需要重新格式化了过程后的变量：

DECLARE @auxDate DATETIME

IF (@dateFrom>@dateTo) 
BEGIN
     SET @auxDate = @dateFrom
     SET @dateFrom = @dateTo
     SET @dateTo = @auxDate
END

     -- Your code..

Answer 4

请查看我已回答Here的问题它处理的案例如下：

@dateFrom ='2014-04-24 13:59:00'
@dateTo ='2014-04-24 14:01:00'

您的代码会为这些值返回错误的日期。
