    Hello,

    I am having issues with calculating sum of time which is time format.

    The regular sum does not seem to work.

    Any help is appreciated.

    Thanks

    I could get to sum time with the following expression

    =TimeSpan.FromTicks(Sum(Fields!TotalTime.Value))

    CREATE FUNCTION fnReturnTotalHoursFromTime(

    @p varchar(14)

    )

    RETURNS decimal(20,6)

    AS

    BEGIN

    DECLARE @hoursColon tinyint, @hours decimal(12,6), @minsColon tinyint, @mins decimal(6,4), @seconds decimal (8,6)

    SELECT @hoursColon = CHARINDEX(':',@p) --Find 1st colon

    SELECT @hours = SUBSTRING(@p,1, @hoursColon -1) --Take all data before the first colon

    SELECT @minsColon = CHARINDEX(':', @p, @hoursColon +1 ) --Find position of second colon

    SELECT @mins = SUBSTRING(@p, @hoursColon +1, @minsColon - @hoursColon -1 ) --Take everything between first and second colon

    SELECT @seconds = SUBSTRING(@p, @minsColon + 1, len(@p) - @minsColon) --Find seconds

    RETURN (@hours) + (@mins / 60) + (@seconds / 3600)

    END

    Then slot that into your select query / stored procedure: SELECT dbo.fnReturnTotalHoursFromTime('4445:44:55') => 4445.748611

    Whole hours? Decimal hours? Hours rounded to the nearest minute, second or ???

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
