Question

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

Answer 1

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)

BEGIN

return rtrim(isnull(cast(nullif((@minutes / 60)
                                , 0
                               ) as varchar
                        ) + 'h '
                    ,''
                   )
            + isnull(CAST(nullif((@minutes % 60)
                                 ,0
                                ) AS VARCHAR(2)
                         ) + 'm'
                     ,''
                    )
            )

end
