arrayMax
is regular function, while maxArray
is an aggregate function. Aggregate functions can't be nested in a single SELECT
query.
the behavior of maxArray is supposed to be same with arrayMax.
Yes, but they are meant to be used in different ways. In this case, it should be written as:
SELECT maxArray(numberArr) AS maxNumber2
FROM
(
SELECT groupArray(number) AS numberArr
FROM
(
SELECT *
FROM numbers(5)
)
)
