SQL Convert total talktime (s) to MM:SS

Question

For my call center I need to calculate average talk time and display them in MM:SS. I have the user involvement time in sec, and the total calls handled:

SELECT sum(usersinvolvedtime)/(sum(numansweredprim)+sum(numansweredover))AS 'Avg Handle time(s)'
FROM calltypefifteenmin
WHERE calltypekey IN (229,230,231,232,233,234,888,889,890,891)
and YEAR (recordtimestamp) = '2014'
AND Month (recordtimestamp) = '7'

As a result I get 238. How to convert that into mm:ss ??

Many thanks in advance..!

Answer 1

Should be something along the following lines:

DECLARE @secs INT = 238;

SELECT 
    CONVERT(VARCHAR(8),  @secs / 60)
    + ':'
    + RIGHT('0' + CONVERT(VARCHAR(2),  @secs % 60), 2);

Answer 2

Try this:

SELECT CAST(238/60 AS VARCHAR) + ':' + CAST(238%60 AS VARCHAR) // 3:58

If you want exactly in MM:SS format

SELECT RIGHT('0' + CAST(238 / 60 AS VARCHAR),2) + ':' + 
       RIGHT('0' + CAST(238 % 60 AS VARCHAR),2)                // 03:58
