### Apache Cloudberry version
2.0.0-incubating-rc2
### What happened
table structure:
create table reference_info
(
uid text,
country text,
ref_uid text,
ref_country text,
ref_year varchar(32)
)
There are 20 million data entries in the database table.
I run sql:
select t.country, t.ref_year, ref_quantity, ref_frequency
from (select country, ref_year, count(*) as ref_frequency from
reference_info group by country, ref_year) t
join
(select country, ref_year, count(*) as ref_quantity
from (select country, ref_year, ref_uid from reference_info group by
country, ref_year, ref_uid) t
group by country, ref_year) u
on t.country = u.country and t.ref_year = u.ref_year;
or
select ref_country, ref_year, count(distinct ref_uid) as cited_quantity,
count(*) as cited_frequency
from reference_info
where country = 'USA'
group by ref_country, ref_year;
is all worked.But
select country, ref_year, count(*) as ref_frequency, count(distinct ref_uid)
as ref_quantity
from reference_info
group by country, ref_year;
is failed ,log is:
