Google bigquery BigQuery，如果基于条件存在重复项，如何返回一个值

我有这张桌子

REGIONID字符串
结算日期时间戳
干预字符串
RRP数字

大多数情况下，干预是0，但在相同的情况下，它有两个记录（0,1），那么RRP必须基于值1，在SQL中如何做到这一点？

以下可用于实现所需结果：

SELECT *, EXCEPT(RN) FROM ( 
  SELECT RRP, ROW_NUMBER() OVER(partition BY REGIONID, SETTLEMENTDATE ORDER BY INTERVENTION DESC) AS RN
)
WHERE RN=1

以下可用于实现预期结果：

SELECT *, EXCEPT(RN) FROM ( 
  SELECT RRP, ROW_NUMBER() OVER(partition BY REGIONID, SETTLEMENTDATE ORDER BY INTERVENTION DESC) AS RN
)
WHERE RN=1

下面是BigQuery标准SQL

#standardSQL
SELECT REGIONID, SETTLEMENTDATE, 
  ARRAY_AGG(STRUCT(INTERVENTION, RRP) ORDER BY INTERVENTION DESC LIMIT 1)[OFFSET(0)].* 
FROM `project.dataset.table` t
GROUP BY REGIONID, SETTLEMENTDATE
