我想根据时间段对标志进行求和。 我试图以两种不同方式在此期间使用sum函数：
id period avg_amt flag
111 1 123.5 1
211 1 143.1 1
311 2 122.1 1
411 3 214.5 1
511 3 124.6 0
611 3 153.2 1
和
select
id, period, avg_amt, flag, sum(flag) over (partition by id order by period)
from dataset
输出未返回我期望的值，即对于期间1 sum = 3，期间2和1，期间3和2。
您能告诉我什么地方出问题了吗？谢谢
答案 0 :(得分：0)
获得简单的总和：
select period, sum(flag) total_flag
from dataset
group by period
在SQL Server中，要重新添加其余信息，可以使用子查询并将其重新加入：
select id, dataset.period, avg_amt, flag, total_flag
from dataset
inner join (
select period, sum(flag) total_flag
from dataset
group by period
) TF on TF.period=dataset.period
我希望使用teradata-sql-assistant仍然可以。
