【问题描述】：
我有这个查询可以帮助我在字符串中找到单独的关键词（对 utm_campaign 和 utm_content 非常有用）：
SELECT
utm_campaign,
splits[SAFE_OFFSET(0)] AS country,
splits[SAFE_OFFSET(1)] AS product,
splits[SAFE_OFFSET(2)] AS budget,
splits[SAFE_OFFSET(3)] AS source,
splits[SAFE_OFFSET(4)] AS campaign,
splits[SAFE_OFFSET(5)] AS audience
FROM (
SELECT
utm_campaign,
SPLIT(REGEXP_REPLACE(
utm_campaign,
r'([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)_([^_]+)_(.+)',
r'\1|\2|\3|\4|\5|\6|\7'),
'|') AS splits
FROM funnel_campaign)
例如：如果我有这样的 umt_campaign：
us_latam_mkt_google_black-friday_audiencie-custom_NNN-NNN_nnn_trafic_responsiv
上面的查询将帮助我用 _ 分隔每个单词。所以我会得到这样的结果：
| utm_campaign | country | product | budget | source | campaign | audience |
|---|---|---|---|---|---|---|
| us_latam_mkt_google_black-friday_audiencie-custom_NNN-NNN_nnn_trafic_responsiv | us | latam | mkt | black-friday | audience-custom |
- 从上面的查询中我想要的是在这种情况下给我
audience列。我尝试将上面的查询添加为 REVENUE 中此查询的子查询，因为在此表中我没有audience列，但我有utm_campaign列。在 utm_campaign 字符串中，第六个片段是观众（对于这个查询，我有错误“标量子查询产生了多个元素”）：

search_flight_pv,

FROM COST_REVENUE
WHERE

AND DATE >= '2019-01-01'
我在这里做错了什么？
我也希望看到 COST 的格式维度与 REVENUE 的格式维度之间的匹配（它不存在，但它在广告系列列中）。
