基于范围 window 框架只能有 1 个排序键

Question

我试过运行下一个查询

select sum(balance) over (partition by client order by card desc, date_tr desc)
from table_1

在结果中我有下一条错误消息：

FAILED: SemanticException Range based Window Frame can have only 1 Sort key

我真的不能在 order by 句子中使用 2 个排序键吗？或者有什么方法可以使用 2 个排序键？

Answer 1

您的代码应该可以工作。 language manual 有一个非常相似的例子。

也就是说，显式 window 子句可能会绕过错误：

select sum(balance) over (partition by client
                          order by card desc, date_tr desc
                          rows between unbounded preceding and current row
                         )
from table_1

Answer 2

请查看此答案以了解 GROUP 和 PARTITION BY 之间的区别，它应该可以工作，但它取决于您到底想要什么：Difference GROUP BY and PARTITION BY
