我的英语说得不太好。抱歉
我想检索该时期的特定数据并汇总这些数据
示例数据集;
CREATE TABLE stackoverflow (
DT date,
Part_number varchAr(10),
sales_volume int
)
insert into stackoverflow values('2018-03-01','HDD','10000');
insert into stackoverflow values('2018-03-01','SDD','50000');
insert into stackoverflow values('2018-03-03','HDD','40000');
insert into stackoverflow values('2018-03-03','SDD','50000');
insert into stackoverflow values('2018-03-05','SDD','90000');
insert into stackoverflow values('2018-03-07','HDD','50000');
insert into stackoverflow values('2018-03-07','HDD','40000');
insert into stackoverflow values('2018-03-08','SDD','20000');
insert into stackoverflow values('2018-03-08','HDD','30000');
insert into stackoverflow values('2018-03-09','SDD','10000');
insert into stackoverflow values('2018-03-11','HDD','20000');
select * from stackoverflow;
这是我尝试过的查询。
select DT,Part_number,sales_volume,SUM(sales_volume) as sum_sv
from stackoverflow
where dt between '2018-03-01' and '2018-03-07'
GROUP BY DT,Part_number,sales_volume
having Part_number='SDD'
order by Part_number;
查询结果
2018-03-01 SDD 50000 50000
2018-03-03 SDD 50000 50000
2018-03-05 SDD 90000 90000
所需的输出
DT Part_number sum_s/v
2018-03-05 SDD 190000
答案 0 :(得分:2)
尝试以下查询:
select max(DT) as DT, Part_number, sum(sales_volume) as sum_sv
from stackoverflow
where dt between '2018-03-01' and '2018-03-07'
and Part_number = 'SDD'
group by Part_number
order by Part_number
