JingDas opened a new pull request, #25500:
URL: https://github.com/apache/doris/pull/25500
## Proposed changes
Support aggregate functions in select without from clause, here are some
examples as following:
`SELECT 1,
'a',
COUNT(),
SUM(1) + 1,
AVG(2) / COUNT(),
MAX(3),
MIN(4),
RANK() OVER() AS w_rank,
DENSE_RANK() OVER() AS w_dense_rank,
ROW_NUMBER() OVER() AS w_row_number,
SUM(5) OVER() AS w_sum,
AVG(6) OVER() AS w_avg,
COUNT() OVER() AS w_count,
MAX(7) OVER() AS w_max,
MIN(8) OVER() AS w_min;`
The query result is as following:
`1|
'a'|count(*)|(sum(1) + 1)|(avg(2) / cast(count(*) as
DOUBLE))|max(3)|min(4)|w_rank|w_dense_rank|w_row_number|w_sum|w_avg|w_count|w_max|w_min|
-+---+--------+------------+-----------------------------------+------+------+------+------------+------------+-----+-----+-------+-----+-----+
1|a | 1| 2| 2.0| 3|
4| 1| 1| 1| 5| 6.0| 1| 7| 8|`
<!--Describe your changes.-->
