Group by in SQL returning error: Selected non-aggregate values must be part of the associated group

Question

我有一个 table 看起来像这样：

       date      store   flag
1    5/4/2018      a       1
2    5/4/2018      a       1
3    5/3/2018      b       1
4    5/3/2018      b       0
5    5/2/2018      a       1
6    5/2/2018      b       0

我想按日期分组并存储和总结标志的数量

即table_a 下面：

       date      store   total_flag
1    5/4/2018      a       2
3    5/3/2018      b       1
4    5/2/2018      a       1
5    5/2/2018      b       0

这就是我正在尝试的：

create multiset volatile table flag_summary as (
 sel table_a.*, SUM(table_a.flag) as total_flag
 group by date, store
)
with data primary index (date, store) on commit preserve rows;

上面给出了一个错误，“创建 TABLE 失败。[3504] 选定的非聚合值必须是关联组的一部分。

Answer 1

您选择了所有 tableA（包括旗帜）。你应该只提取日期和商店，因为你想要标志的总和。

SELECT date, store, SUM(flag)
FROM tableA
GROUP BY date, store
