How to convert number of minutes to hh:mm format in TSQL?

I have a select query that has DURATION column to calculate number of Minutes . I want to convert those minutes to hh:mm format.

Duration has values like 60, 120,150

For example:

60 becomes 01:00 hours

120 becomes 02:00 hours

150 becomes 02:30 hours

Also, this is how I retrieve DURATION (Minutes)

DATEDIFF(minute, FirstDate,LastDate) as 'Duration (Minutes)'

You can convert the duration to a date and then format it:

DECLARE @FirstDate datetime, @LastDate datetime SELECT @FirstDate = '2000-01-01 09:00:00', @LastDate = '2000-01-01 11:30:00' SELECT CONVERT(varchar(12), DATEADD(minute, DATEDIFF(minute, @FirstDate, @LastDate), 0), 114) /* Results: 02:30:00:000 */ 

For less precision, modify the size of the varchar:

SELECT CONVERT(varchar(5), DATEADD(minute, DATEDIFF(minute, @FirstDate, @LastDate), 0), 114) /* Results: 02:30 */ 

This function is to convert duration in minutes to readable hours and minutes format. i.e 2h30m. It eliminates the hours if the duration is less than one hour, and shows only the hours if the duration in hours with no extra minutes.

CREATE FUNCTION [dbo].[MinutesToDuration] ( @minutes int ) RETURNS nvarchar(30) AS BEGIN declare @hours nvarchar(20) SET @hours = CASE WHEN @minutes >= 60 THEN (SELECT CAST((@minutes / 60) AS VARCHAR(2)) + 'h' + CASE WHEN (@minutes % 60) > 0 THEN CAST((@minutes % 60) AS VARCHAR(2)) + 'm' ELSE '' END) ELSE CAST((@minutes % 60) AS VARCHAR(2)) + 'm' END return @hours END 

To use this function :

SELECT dbo.MinutesToDuration(23) 

Results: 23m

SELECT dbo.MinutesToDuration(120) 

Results: 2h

SELECT dbo.MinutesToDuration(147) 

Results: 2h27m

Hope this helps!

I'm not sure these are the best options but they'll definitely get the job done:

declare @durations table ( Duration int ) Insert into @durations(Duration) values(60),(80),(90),(150),(180),(1000) --Option 1 - Manually concatenate the values together select right('0' + convert(varchar,Duration / 60),2) + ':' + right('0' + convert(varchar,Duration % 60),2) from @Durations --Option 2 - Make use of the time variable available since SQL Server 2008 select left(convert(time,DATEADD(minute,Duration,0)),5) from @durations GO 

DECLARE @Duration int SET @Duration= 12540 /* for example big hour amount in minutes -> 209h */ SELECT CAST( CAST((@Duration) AS int) / 60 AS varchar) + ':' + right('0' + CAST(CAST((@Duration) AS int) % 60 AS varchar(2)),2) /* you will get hours and minutes divided by : */ 

For those who need convert minutes to time with more than 24h format:

DECLARE @minutes int = 7830 SELECT CAST(@minutes / 60 AS VARCHAR(8)) + ':' + FORMAT(@minutes % 60, 'D2') AS [Time] 

Result:

130:30 

Thanks to A Ghazal, just what I needed. Here's a slightly cleaned up version of his(her) answer:

create FUNCTION [dbo].[fnMinutesToDuration] ( @minutes int ) RETURNS nvarchar(30) -- Based on AS BEGIN return rtrim(isnull(cast(nullif((@minutes / 60) , 0 ) as varchar ) + 'h ' ,'' ) + isnull(CAST(nullif((@minutes % 60) ,0 ) AS VARCHAR(2) ) + 'm' ,'' ) ) end 

This seems to work for me:

SELECT FORMAT(@mins / 60 * 100 + @mins % 60, '#:0#')

select convert(varchar(5),dateadd(mi,DATEDIFF(minute, FirstDate,LastDate),'00:00'),114) 

In case someone is interested in getting results as 60 becomes 01:00 hours, 120 becomes 02:00 hours, 150 becomes 02:30 hours, this function might help:

 create FUNCTION [dbo].[MinutesToHHMM] ( @minutes int ) RETURNS varchar(30) AS BEGIN declare @h int set @h= @minutes / 60 declare @mins varchar(2) set @mins= iif(@minutes%60<10,concat('0',cast((@minutes % 60) as varchar(2))),cast((@minutes % 60) as varchar(2))) return iif(@h <10, concat('0', cast(@h as varchar(5)),':',@mins) ,concat(cast(@h as varchar(5)),':',@mins)) end 

I would do the following (copy-paste the whole stuff below into immediate window / query window and execute)

DECLARE @foo int DECLARE @unclefoo smalldatetime SET @foo = DATEDIFF(minute, CAST('2013.01.01 00:00:00' AS datetime),CAST('2013.01.01 00:03:59' AS datetime)) -- AS 'Duration (Minutes)' SET @unclefoo = DATEADD(minute, @foo, '2000.01.01') SELECT CAST(@unclefoo AS time) 

@foo stores the value you generate in your question. The "trick" comes by then:
we create a smalldatetime variable (in my case it's yyyy.mm.dd format) and increment it with your int value, then display (or store if you want) the time part only.

declare function dbo.minutes2hours ( @minutes int ) RETURNS varchar(10) as begin return format(dateadd(minute,@minutes,'00:00:00'), N'HH\:mm','FR-fr') end
