У меня есть записи, сгруппированные по ID1 и ID2, такие как:
ID1 ID2 date_time

Я пытаюсь извлечь записи, которые имеют максимальную запись за определенный промежуток времени, например, если я хочу извлечь записи с максимальным временем не больше полудня 9 марта, вышеупомянутые записи будут установлены на:
ID1 ID2 date_time

Я использовал cast(regexp_replace('2020-03-09T16:05:06:827Z','(.*?)T(.*?):([^:]*?)Z$','$1 $2\\.$3') as timestamp) для преобразования date_time в отметку времени благодаря @ leftjoin.
Благодарим за любую помощь.
Добавлена проблема с вершинами после поднабора времени:
Примечание: мне разрешено создавать только временные таблицы.
Первое: я дедуплирую необработанный набор данных по ID1 и ID2
create temporary table data1 as
select id1, id2, name, value,
cast(regexp_replace(oldtime,'(.*?)T(.*?):([^:]*?)Z$','$1 $2\\.$3') as timestamp) as date_time
from (
select ID1, ID2,
ROW_NUMBER() OVER (PARTITION BY id1, id2,name, value ORDER BY value) as rn,
case when name like '%_TIME' then value end as date_time
from df.data1
)undup
where undup.rn = 1 AND
value <> '' and value is not null
order by ID1, ID2, date_time ASC
, затем я подмножество времени:
create temporary table data2 as
select *
from(
select *,
max(date_time) over (partition by id1,id2) as max_date
from data1
) s
where max_date <= '2020-03-12 12:00:00'
После этого я получаю ошибку вершины ..
