在查询oracle中显示数据，但不包括重复数据

Question

您能帮我吗，我的查询有问题。 我有像波纹管这样的数据：

+------------+---------+-----+
|    Date    | Prod_ID | Qty |
+------------+---------+-----+
| 01/02/2018 | Pencil  |   2 |
| 01/02/2018 | pencil  |   3 |
| 01/02/2018 | pencil  |   4 |
| 01/02/2018 | book    |   5 |
| 01/02/2018 | ruller  |   1 |
+------------+---------+-----+

但我的结果是波纹管

+------------+---------+-----+
|    Date    | Prod_ID | Qty |
+------------+---------+-----+
| 01/02/2018 |       5 |  15 |
+------------+---------+-----+

我需要下面的结果

+------------+---------+-----+
|    Date    | Prod_ID | Qty |
+------------+---------+-----+
| 01/02/2018 |       3 |  15 |
+------------+---------+-----+

使用我的查询脚本

select "date",
    Prod_ID,
    Qty,
from data
group by "date",
    Prod_ID,
    Qty,
order by "date";

谢谢

您可以尝试以下操作：

select "date",
    Count(Distinct Prod_ID) as total_product_count,
    Sum(Qty) as qty
from 
    data
group by 
    "date"
order by "date";
