SQL Script for time in time format

Hello Experts Exchange
I have a table that has two columns [Tool Code] and [Total Down Time], I want to sum the time in the [Total Down Time] field grouped by the [Tool Code].  The [Total Down Time] column is in the format of 00:00:00.

When I run the following script the [Total Down Time] comes back as a decimal number but I want it to come back as a hour:minute:second format.

Select [Tool Code], Sum(DateDiff(Minute, '0:00:00',[Total Down Time])) as [Total Down Time]
From [dbo].[Acc_Data]
Where [Bay N°] = '3'
and [Reported Date] between '09/12/2014' and '09/12/2014'
Group by [Tool Code]
Order by [Tool Code]

Open in new window


Here is want is returned;
Tool Code      Total Down Time
D250                            78
DM25                            1216
M116                            413
M133                            106
Not Set                             82

I want to see something like this;
Tool Code      Total Down Time
D250                           01:18:00

declare @TimeinSecond int=1234;
SELECT RIGHT('0' + CAST(@TimeinSecond / 3600 AS VARCHAR),2) + ':' +
RIGHT('0' + CAST((@TimeinSecond / 60) % 60 AS VARCHAR),2)  + ':' +
RIGHT('0' + CAST(@TimeinSecond % 60 AS VARCHAR),2)

>>> 00:20:34
oops, yours in in minutes :) just multiply it by 60 to find second...

or find the difference in second before using the code above... all 59 seconds can make huge difference when summed up :) so be precise, get total in sec first then convert it to hh:mm:ss

if you wish you can use 00 as last part in the code above...

Sum(DateDiff(Minute, '0:00:00',[Total Down Time])) as [Total Down Time]
>>>
Sum(DateDiff(second, '0:00:00',[Total Down Time])) as [Total Down Time]

Hello HainKurt
How do I integrate your code into my query?

>The [Total Down Time] column is in the format of 00:00:00.
Q1:  What is the data type of this column?  Date, datetime, varchar...
Q2:  Give us a sample data set to work with.

Offhand, you should be able to sum a time column using SUM(x), or even sum a date column as SUM(CAST(x as time))...
I think this solution can work for you:
Select [Tool Code], Convert(time,dateadd(minute,Sum(DateDiff(Minute, '0:00:00',[Total Down Time])),0),108) as [Total Down Time]
From [dbo].[Acc_Data]
Where [Bay N°] = '3'and [Reported Date] between '09/12/2014' and '09/12/2014'
Group by [Tool Code]

what happened to the my solutions? no comment? did not work?
the one i posted is perfectly fine:

with x as (
Select 'D250' [Tool Code], 78*60 as [Total Down Time]
union select'DM25', 1216*60 
union select 'M116', 413*60
union select 'M133', 106*60
) select [Tool Code], RIGHT('0' + CAST([Total Down Time] / 3600 AS VARCHAR),2) + ':' +
RIGHT('0' + CAST(([Total Down Time] / 60) % 60 AS VARCHAR),2)  + ':' +
RIGHT('0' + CAST([Total Down Time] % 60 AS VARCHAR),2) as [Total Down Time (sec)]
from x
Order by [Tool Code]

Tool Code	Total Down Time (sec)
D250	01:18:00
DM25	20:16:00
M116	06:53:00
M133	01:46:00

Hello Experts Exchange
After more work I have found that HainKurt solution is a better query and gives me a better amount of time calculation.


with x as (
Select [Tool Code], Sum(DateDiff(second, '0:00:00',[Total Down Time])) as [Total Down Time]
From [dbo].[Acc_Data]
Where [Bay N°] = '3'
and [Reported Date] between '09/12/2014' and '09/12/2014'
Group by [Tool Code]
) select [Tool Code], RIGHT('0' + CAST([Total Down Time] / 3600 AS VARCHAR),2) + ':' +
RIGHT('0' + CAST(([Total Down Time] / 60) % 60 AS VARCHAR),2)  + ':' +
RIGHT('0' + CAST([Total Down Time] % 60 AS VARCHAR),2) as [Total Down Time (sec)]
from x
