Efficient way to convert second to minute and seconds in sql server 2005

Question

Suppose I have 90 seconds. If I want to display the result in terms of minutes and second, I do it by using

select Time= \'0\' + CAST( 90/60 as varchar(2)) +         


        

Answer 1

With hours:

SELECT CONVERT(CHAR(8),DATEADD(second,90,0),108)
00:01:30

Ignoring hours:

SELECT RIGHT(CONVERT(CHAR(8),DATEADD(second,90,0),108),5)
01:30
