我试图查询和总结的数据是持卡人的日常交易数据。我试图先每天汇总,然后再累积。我可以按天成功汇总,但是当我添加以下行时:
sum(custs_spent_at_least_once) over (order by day rows unbounded preceding) as cum_total
我收到错误“关系卡不存在”
我有一个不同的查询,它使用相同的代码行执行类似的操作。
这是我的代码,可以按天累计汇总。

select
[first_trans_date:aggregation] as period,
count(member_uuid) as custs_spent_at_least_once
