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

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

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 : */
