Hello experts,

I have a table with two columns, the initial date and the final date.
I know how calculate days hours and minutes between them with datediff.

But i need to calculate the total days, hours and minutes of all rows in the end.

inidate                      enddate                      result
01/01/2014 01:30      02/01/2014 03:00      1d 1h 30m
03/01/2014 01:30      05/01/2014 03:00      2d 1h 30m
            
            Total: 2d 3h 00m

Anyone know a easy way to do this?

Thx in advanced,
Miguel

E.g.

DECLARE @Sample TABLE
    (
      BeginDateTime DATETIME ,
      EndDateTime DATETIME
    );

INSERT  INTO @Sample
        ( BeginDateTime, EndDateTime )
VALUES  ( '01/01/2014 01:30', '02/01/2014 03:00' ),
        ( '03/01/2014 01:30', '05/01/2014 03:00' );

WITH    Mins
          AS ( SELECT   * ,
                        DATEDIFF(MINUTE, BeginDateTime, EndDatetime) AS Mins ,
                        SUM(DATEDIFF(MINUTE, BeginDateTime, EndDatetime)) OVER ( ORDER BY BeginDateTime ) AS SumMins
               FROM     @Sample
             )
    SELECT  * ,
            Mins / ( 24 * 60 ) AS d ,
            ( Mins % ( 24 * 60 ) ) / 60 AS h ,
            ( Mins % ( 24 * 60 ) ) % 60 AS m ,
            SumMins / ( 24 * 60 ) AS sd ,
            ( SumMins % ( 24 * 60 ) ) / 60 AS sh ,
            ( SumMins % ( 24 * 60 ) ) % 60 AS sm
    FROM    Mins;

Hi ste5an,

Thank you fo your post.
But that does what i already know, like i said in the post.. you're calculating the total days, hours and mins in each row.

What i need is to have a final sum of all rows.

DECLARE @Test TABLE
(
	inidate		DATETIME,
	enddate		DATETIME
);

INSERT INTO @Test (inidate, enddate)
VALUES ('1/1/2014 01:30', '2/1/2014 09:00'),
	('3/1/2014 01:30', '5/1/2014 03:00'),
	('2/15/2014 12:34:56', '2/28/2014 01:23:45'),
	('3/4/2014 15:45:22', '3/4/2014 16:00:25');
	
WITH cte
AS
(
	SELECT inidate, enddate,
		DATEDIFF(DAY, inidate, enddate) AS d,
		DATEDIFF(HOUR, inidate, enddate) % 24 AS h,
		DATEDIFF(MINUTE, inidate, enddate) % 60 AS m
	FROM @Test
	WHERE enddate > inidate
)
SELECT inidate, enddate, d, h, m
FROM cte
UNION ALL
SELECT NULL, NULL,
	SUM(d) + ((SUM(h) + (SUM(m) / 60)) / 24), ((SUM(h) + (SUM(m) / 60)) % 60) % 24, SUM(m) % 60
FROM cte

The math for the total is the same as for the row. Thus the running sum sample..
