Вы можете сделать это следующим образом (не слишком причудливо, но прямого пути нет).Чтобы упростить его, я просто объединил обе выходные даты
-- before Hive 1.3
select
case
when ceil(month(mydate)/ 3.0) = 1 then concat("Jan 01 ",year(mydate),"|","Mar 31 ",year(mydate))
when ceil(month(mydate)/ 3.0) = 2 then then concat("Apr 01 ",year(mydate),"|","Jun 30 ",year(mydate))
when ceil(month(mydate)/ 3.0) = 3 then then concat("Jul 01 ",year(mydate),"|","Sep 30 ",year(mydate))
when ceil(month(mydate)/ 3.0) = 4 then then concat("Oct 01 ",year(mydate),"|","Dec 31 ",year(mydate))
else
null
end,
ceil(month(mydate)) as quarter
from (
select
from_unixtime(unix_timestamp('Feb 03 2014' , 'MMM dd yyyy')) as mydate
) t;
--Hive 1.3 or higher
select
case
when quarter(mydate) = 1 then concat("Jan 01 ",year(mydate),"|","Mar 31 ",year(mydate))
when quarter(mydate) = 2 then then concat("Apr 01 ",year(mydate),"|","Jun 30 ",year(mydate))
when quarter(mydate) = 3 then then concat("Jul 01 ",year(mydate),"|","Sep 30 ",year(mydate))
when quarter(mydate) = 4 then then concat("Oct 01 ",year(mydate),"|","Dec 31 ",year(mydate))
else
null
end,
ceil(month(mydate)) as quarter
from (
select
from_unixtime(unix_timestamp('Feb 03 2014' , 'MMM dd yyyy')) as mydate
) t;
