Sql server 2012 如何在SQL Server中的Pivot中将秒转换为小时分钟

我在SQLServer2012中编写了一个pivot查询。它工作正常，在行下显示用户名的结果，在列下显示以秒为单位的生产小时数总和。但是我需要把秒分成小时：分钟的格式。请帮我查询一下

declare @empid nvarchar(20), @fromdate date, @todate date, @cols nvarchar(max), @query  AS VARCHAR(MAX), @dt varchar(20), @dt1 varchar(20) 

set @empid = 'EC0100'
set @fromdate = '10/01/13'
set @todate = '10/31/13'
set @dt='Exceptions'
set @dt1='Tech Issues'

select @cols = STUFF((SELECT distinct ',' + QUOTENAME(convert(nvarchar(20),c._Date, 101))
         FROM MIS_BM_Calendar c
         where c._Date between @fromdate and @todate and _Day not in
('Sunday')
         FOR XML PATH(''), TYPE
         ).value('.', 'NVARCHAR(MAX)')
     ,1,1,'')

set @query= 'select UserName, '+@cols+' from 
(select  e.UserName, c._Date , (SUM(DATEDIFF(SS,0,c.TimeTaken))) As TimeTaken
 from MIS_BM_Users e 
 inner join MIS_Opus c 
 on e.EmpId=c.EmpId 
 where (e.AccountManagerID='''+@empid+''') and c.Category not in ('''+@dt+''','''+@dt1+''')
 group by c._Date, e.UserName
) As SourceTable
Pivot
(
SUM(TimeTaken) for _Date in ('+@cols+')
) As Pvt'

execute(@query)

一分钟和一小时内的秒数是恒定的。一分钟60秒，一小时3600秒。透视查询对此没有影响

因此，你的问题变成了如何将秒转换成小时、分钟和秒。因为你在2012年，你有一个方便的dandy TimeFromParts功能，所以你可以看到你需要在几小时、几分钟和几秒钟内为它提供信息

WITH SRC (TimeTaken) AS
(
    SELECT ROW_NUMBER() OVER (ORDER BY (SELECT NULL))
    FROM sys.all_columns AS AC
)
, Proof AS
(
    -- this logic is valid as long as TimeTaken is less than 24 hours
    -- or 86400 (24 * 60 * 60) seconds
    SELECT 
        SRC.TimeTaken
        -- integer division drops remainder
    ,   SRC.TimeTaken / 3600 AS Hours
        -- integer division and modulo operator to keep legit values
    ,   (SRC.TimeTaken / 60) % 60  AS Minutes
        -- modulo to have values 0 - 59
    ,   SRC.TimeTaken % 60 AS Seconds
    FROM
        SRC
)
SELECT
    P.TimeTaken
,   P.Hours
,   P.Minutes
,   P.Seconds
,   TIMEFROMPARTS(P.Hours, P.Minutes, P.Seconds, 0, 0) AS TimeTakenTimeType
FROM
    Proof AS P;

我创建了一个标量函数，并将秒数转换为hhmms。然后在主查询中包含该函数

ALTER function [dbo].[ConvertSecondsToHHMMSS]
(
@TotalSeconds int
)
Returns nvarchar(20)
As
Begin
declare @hours int, @minutes int, @seconds int, @result nvarchar(20)

set @hours = @TotalSeconds / 3600
set @minutes = (@TotalSeconds % 3600) / 60
set @seconds = @TotalSeconds % 60

set @result =  CONVERT(nvarchar(20),@hours) + ':' + CONVERT(nvarchar(20),@minutes) + ':' +CONVERT(nvarchar(20),@seconds)

return @result
end

主要查询：

set @query= 'select UserName, '+@cols+' from
(
select  e.UserName, c._Date, dbo.ConvertSecondsToHHMMSS(SUM(DATEDIFF(SS,0,c.TimeTaken))) As TimeTaken from MIS_BM_Users e 
inner join MIS_Opus c on e.EmpId=c.EmpId 
where (e.AccountManagerID='''+@AccountManagerId+''')
and c.Category not in ('''+@Condition1+''', '''+@condition2+''')
group by c._Date, e.UserName
) As SourceTable
Pivot
(
MIN(TimeTaken) for _Date in ('+@cols+')
) As Pvt'

execute(@query)

谢谢你的建议，但是我无法在pivot中实现这一点。所以我创建了一个标量函数并得到了结果。请看下面我的答案。
