Question

我想添加两个时间戳，例如＆＃39; 03：59：39＆＃39; 03：43：04＆＃39;在SQL Server中我需要两个时间戳之和的结果是7小时42分43秒。

没有任何演员......任何人都可以建议吗？

Answer 1

TRY this

    DECLARE @TIME1 TIME(0)
        ,@TIME2 TIME(0);

    SELECT @TIME1 = CONVERT(TIME(0), '2013-07-20 03:59:39')
        ,@TIME2 = CONVERT(TIME(0), '2013-07-25 03:43:04');

    SELECT @TIME1 AS [@REQUESTEDTIME]
        ,@TIME2 AS [@TIMEINTERVEL];

    SELECT DATEADD(SECOND, DATEDIFF(SECOND, '00:00:00', @TIME1), @TIME2) AS FINALRESULT;

Try this one also

DECLARE @TimeVal TIME
    ,@TotalTime TIME;

SET @TimeVal = '03:59:39';
SET @TotalTime = '03:43:04'

SELECT @TimeVal
    ,@TotalTime
    ,dateadd(hour, DATEPART(HOUR, @TotalTime), dateadd(minute, DATEPART(MINUTE, @TotalTime), dateadd(ss, DATEPART(SECOND, @TotalTime), @TimeVal)))
