I have a query such that the query’s result is:

SELECT CONVERT(VARCHAR(8),(MAX(END_TIME)-MIN(START_TIME)),108) as DURATION WHERE ... GROUP BY TITLE

For each title, DURATION is different. The query returns:

    Convert minutes into seconds

    SUM() the seconds

    Convert back to minutes

    The following will give you the SUM of seconds:

    SET @Seconds = SELECT SUM(DATEDIFF(SECOND, [START_TIME], [END_TIME]))

    The following then turns that into a datetime object:

    select convert(varchar(8), dateadd(second, @Seconds, 0),  108)

    Or as 1 query:

    SELECT convert(varchar(8), dateadd(second, SUM(DATEDIFF(SECOND, [START_TIME], [END_TIME])), 0),  108)
