Google cloud platform 参数类型数组中的运算符没有匹配的签名<；字符串>；

我想使用“WHERE xxx IN（'aaa'，'bbb'）执行以下标准SQL

但出现了错误。 是否可以在标准SQL中使用“IN”

标准SQL

SELECT commit, author.name, committer.name, committer.time_sec,
committer.tz_offset, committer.date.seconds , subject, message,
repo_name
FROM `bigquery-public-data.github_repos.commits`
WHERE repo_name IN 
('tensorflow/tensorflow', 'facebook/react')

错误

在标准SQL中，您不可能真正做到这一点。但在这篇文章中，他们解释得很好

这就是你如何得到你想要的结果，我认为：

SELECT commit, author.name as author_name, committer.name as committer_name, committer.time_sec,
committer.tz_offset, committer.date.seconds , subject, message,
repo_name
FROM `bigquery-public-data.github_repos.commits`
CROSS JOIN UNNEST(repo_name) as repo_names_unnested
WHERE repo_names_unnested IN ('tensorflow/tensorflow', 'facebook/react')

请注意，您不能同时拥有

author.name

和

committer.name

，因为两者都将显示为

name

。因此，我将它们改为

作者名

和

提交人名

我还认为您实际上正在寻找的是用

repo\u names\u unnested

替换

repo\u name

的结果，所以请尝试在SELECT子句中也替换它。

字段“repo\u name”重复（遗留SQL）或数组（标准SQL），这在运算符中不支持标准SQL。要将一个数组转换成一组行，您可以使用我的方法。

下面是BigQuery标准SQL

如果您需要保留原始记录，只需在repo_名称中输出带有“tensorflow/tensorflow”、“facebook/react”的记录：

#standardSQL
SELECT commit, author.name AS author_name, committer.name AS committer_name, committer.time_sec,
committer.tz_offset, committer.date.seconds , subject, message,
repo_name
FROM `bigquery-public-data.github_repos.commits`
WHERE EXISTS (
  SELECT 1 FROM UNNEST(repo_name) name WHERE name IN ('tensorflow/tensorflow', 'facebook/react') 
)

非常感谢你。我已经按照您的建议，将select子句中未列出的回购名称替换为回购名称。太棒了@yukiotakai！如果它有效，请将我的答案标记为正确答案：）谢谢您的日常支持。每次，我都有很多东西要向你学习。此外，我还感谢stack over flow和GCP支持团队！
