如何在BigQuery中检查列表中是否有多个值

Question

有没有办法让这个子句更紧凑？

SELECT campaign
,event_list
FROM `adobe_analytics.raw_data_20200*`
WHERE campaign IS NOT NULL  -- What does it mean when a campaign is null in Adobe_analytics
AND
(
"1" IN UNNEST(split(event_list,","))
OR "2" IN UNNEST(split(event_list,","))
OR "3" IN UNNEST(split(event_list,","))
)

类似于：

SELECT campaign
,event_list
FROM `adobe_analytics.raw_data_20200*`
WHERE campaign IS NOT NULL
AND ("1" OR "2" OR "3") IN UNNEST(split(event_list,","))

Answer 1

我会使用exists:

SELECT campaign, event_list
FROM `adobe_analytics.raw_data_20200*` rd
WHERE campaign IS NOT NULL AND
EXISTS (SELECT 1
FROM UNNEST(SPLIT(rd.event_list)) el
WHERE el IN ('1', '2', '3')
);

Answer 2

下面是BigQuery标准SQL

SELECT campaign ,event_list
FROM `adobe_analytics.raw_data_20200*`
WHERE campaign IS NOT NULL
AND (
SELECT COUNT(1) FROM UNNEST(SPLIT(event_list,",")) e
JOIN UNNEST(SPLIT("1,2,3",",")) e USING(e)
) > 0
