Description

create table sales (s_qty bigint, s_item_sk bigint) partitioned by(s_region string, s_date date);

insert into sales partition(s_region='USA', s_date='2018-01-01') values (1,1), (2,2);
insert into sales partition(s_region='EU', s_date='2018-02-01') values (1,1), (2,2);

select count(*) from sales s, agg_sales a where concat(a.s_region, '^', a.s_date) = concat(s.s_region, '^', s.s_date) and s.sold_qty > a.median_s_qty and a.s_item_sk = s.s_item_sk;

select count(*) from sales s, agg_sales a where (a.s_region, a.s_date) = (s.s_region, s.s_date) and s.sold_qty > a.median_s_qty and a.s_item_sk = s.s_item_sk; 

select count(*) from sales s, agg_sales a where a.s_region = s.s_region and  a.s_date = s.s_date and s.sold_qty > a.median_s_qty and a.s_item_sk = s.s_item_sk;
