converting minutes to hour:minutes:second in sql

Question

I have a table transaction like this:

transactID    Paydate                   DelDate                     vtid
24            2013-05-08 16:53:03         


        

Answer 1

If you want to convert minutes or seconds to hh:mm:ss format then you could use these functions (DATEADD,CONVERT with style 114 and LEFT):

DECLARE @PayDate     DATETIME,
        @DelDate     DATETIME,
        @DiffSeconds INT,
        @DiffMinutes INT;

SELECT  @PayDate='2013-05-08T16:53:03.000',
        @DelDate='2013-05-08T17:00:28.000',
        @DiffSeconds=DATEDIFF(SECOND,@PayDate,@DelDate),
        @DiffMinutes=DATEDIFF(MINUTE,@PayDate,@DelDate);


SELECT  @DiffSeconds AS Diff_Seconds,
        LEFT(CONVERT(VARCHAR(50),DATEADD(SECOND,@DiffSeconds,0),114),8) AS Diff_From_Seconds,
        @DiffMinutes AS Diff_Minutes,
        LEFT(CONVERT(VARCHAR(50),DATEADD(MINUTE,@DiffMinutes,0),114),8) AS Diff_From_Minutes;

Results:

Diff_Seconds Diff_From_Seconds Diff_Minutes Diff_From_Minutes
------------ ----------------- ------------ -----------------
445          00:07:25          7            00:07:00

Answer 2

marc_s is right with his comment. What you need is a function like in this answer.

You would then call it like this:

SELECT 
     udfTimeSpanFromSeconds(SUM(DATEDIFF(SECOND, t.Paydate, t.DelDate))) AS 'HH:MM:SS'
FROM 
     Transaction_tbl t 
WHERE 
     t.transactID in (24, 25) 
group by 
     vtid
