如何获取SQL中特定分组中的每条记录（希望通过索引）？

Question

我有一个Impala查询，使用group by on many colums将数百万条记录聚合成组

select col1, col3, col5, col7, col23 col24, count(*) as count 
from my_table 
group by col1, col3, col5, col7, col23 col24

结果：

col1, col3, col5, col7, col23 col24, count
John, Michaels, USD, ABC, 123, AA, 1243560969
Ryan, Jones, USD, FCC, 101, BB, 5043855
James, Gerrity, YEN, FCC, 102, BA, 37876899

如何获取SQL中特定分组中的每条记录（希望通过索引）？

我正在寻找像

这样的东西

SELECT * 
FROM GROUP 3 IN (
  select col1, col3, col5, col7, col23 col24, count(*) as count 
  from y_table 
  group by col1, col3, col5, col7, col23 col24, count
)

你认为这是可能的吗？任何建议都非常感谢！

Answer 1

尝试：

select col1, col3, col5, col7, col23, col24,
 count(*) as cnt, some_function_to_form_groups as grp 
from my_table 
group by col1, col3, col5, col7, col23, col24 
having grp = 3

some_function_to_form_groups可以left(col1,1) {or equivalent}获得缩写等。
