Hello,
I'm converting from MySQL to PostgreSQL (actually flipping/flopping back) and have a question:
MySQL has a cool function sec_to_time() which converts your number of seconds to hh:mm:ss
I've read thru the mailing lists and am basically trying to implement the following:
MySQL:
select sec_to_time(sum(unix_timestamp(enddate) - unix_timestamp(startdate))) from foo;
PostgreSQL:
select XXX(sum(date_part('epoch',enddate) - date_part('epoch',startdate))) from foo;
I just need to know what XXX is/can be. I've tried a lot of combinations of the documented functions and come up with useless conversions.
Thanks,
George Johnson
PS: i can't find documentation on how to load the functions in contrib. I can compile and
install them O.K., but not sure how to make them load.
