Re: Average of Duration coming in hhh:mi:ss format

You could do it the long way, multiplying hours by 3600, etc., or simply cast these durations as intervals.  For example, you can do this in BTEQ or Studio:

create table times (id int, hms interval hour(3) to second) unique primary index(id);

insert into times values(1, '20:32:37');
insert into times values(2, '67:55:50');
insert into times values(3, '58:36:35');
insert into times values(4, '106:32:11');
insert into times values(5, '91:30:39');

select avg(hms) from times   produces:  69:01:34.400000
