How can I convert decimals hours into hours and minutes in this procedure

Question

I have a stored procedure that returns 4 columns of data

• Supporthoursworked (This is returned in minutes and multiplied to by 60)
• SupportHoursCharged
• DevelopmentHoursWorked (Also returned in minutes and multiplied)
• DevelopmentHoursCharged

My problem is that it currently returns those values in decimal form, and am struggling to convert these values into standard times,

How do i go about amending this procedure into returning the times correctly?

USE [Database]
GO

Answer 1

If you want it as standard date time, u can use this expression:

dateadd(mi,SUM(SupportHoursWorked)*60,'00:00')  

If you want it "beautiful":

select CONVERT(VARCHAR(8), dateadd(mi,SUM(SupportHoursWorked)*60,'00:00'), 108) 'hh:mi:ss'

Answer 2

For Sql Server 2012 and above:

SELECT timefromparts(SUM(SupportHoursWorked), 0, 0, 0, 0)

General:

SELECT DATEADD(hh, SUM(SupportHoursWorked), CAST('00:00:00' AS TIME))

EDIT:

Replace :

Select 
  FromDate
, SUM(SupportHoursWorked)       AS SupportHoursWorked
, SUM(SupportHoursCharged)      AS SupportHoursCharged
, SUM(DevelopmentHoursWorked)   AS DevelopmentHoursWorked
, SUM(DevelopmentHoursCharged)  AS DevelopmentHoursCharged

with:

Select 
  FromDate
, DATEADD(mi, SUM(SupportHoursWorked)*60 , CAST('00:00:00' AS TIME))      AS SupportHoursWorked
, DATEADD(mi, SUM(SupportHoursCharged)*60, CAST('00:00:00' AS TIME))      AS SupportHoursCharged
, DATEADD(mi, SUM(DevelopmentHoursWorked)*60, CAST('00:00:00' AS TIME))   AS DevelopmentHoursWorked
, DATEADD(mi, SUM(DevelopmentHoursCharged)*60, CAST('00:00:00' AS TIME))  AS DevelopmentHoursCharged

Answer 3

I think there's a simple answer. Try just casting them to Time datatype. Time prints out like hh:mm:ss[.nnnnnnn]
