Google bigquery BigQuery:无法创建视图。想不到的请再试一次

我正在尝试在BigQuery中保存视图，并不断收到相同的错误：

Failed to create view. Unexpected. Please try again.

查询如下：

SELECT
interaction.id AS Interaction.ID,
interaction.author.name AS Interaction.Author.Name,
interaction.author.username AS Interaction.Author.Username,
interaction.content AS Interaction.Content,
interaction.created_at_timestamp AS Interaction.Created_At_Timestamp,
klout.score AS Klout.Score,
twitter.geo.latitude AS Twitter.Geo.Latitude,
twitter.geo.longitude AS Twitter.Geo.Longitude,
twitter.media.expanded_url AS Twitter.Media.ExpandedUrl,
twitter.media.type AS Twitter.Media.Type,
twitter.place.country AS Twitter.Place.Country,
twitter.user.followers_count AS Twitter.User.Followers,
twitter.user.friends_count AS Twitter.User.Friends,
twitter.user.listed_count AS Twitter.User.Listed,
twitter.retweet.count AS Twitter.Retweet.Count
FROM
[**DATASET_NAME_OMITTED**.main_table]
WHERE
(interaction.id IS NOT NULL)
AND (interaction.created_at_timestamp IS NOT NULL)
AND (interaction.created_at_timestamp >= DATE_ADD(USEC_TO_TIMESTAMP(UTC_USEC_TO_HOUR(NOW())), -1, "DAY"))
AND (interaction.created_at_timestamp < USEC_TO_TIMESTAMP(UTC_USEC_TO_HOUR(NOW())))

我确实注意到twitter.media是重复记录类型。尽管如此，删除twitter.media.*字段并不能解决这个问题

我已经能够成功地保存具有相同时间戳限制和命名约定的其他视图。试图保存此文件始终失败

对于上下文：此表由DataSift通过其BigQuery连接器填充（默认为catch all模式）。

这真的很奇怪。 我做了一个实验，取出了每个alias操作，结果都成功了。 然后，我慢慢地将其中的一些添加回，然后再次添加；它继续工作。然而，似乎某些别名不想工作（我不知道为什么）。 我最终得出以下结论，其中包含了您的大部分别名，并且似乎按照预期工作：

SELECT
interaction.id AS Interaction.ID,
interaction.author.name AS Interaction.Author.Name,
interaction.author.username AS Interaction.Author.Username,
interaction.content AS Interaction.Content,
interaction.created_at_timestamp AS Interaction.Created_At_Timestamp,
klout.score AS Klout.Score,
twitter.geo.latitude AS Twitter.Geo.Latitude,
twitter.geo.longitude AS Twitter.Geo.Longitude,
twitter.media.expanded_url,
twitter.media.type AS Twitter.Media.Type,
twitter.place.country AS Twitter.Place.Country,
twitter.user.followers_count,
twitter.user.friends_count,
twitter.user.listed_count,
twitter.retweet.count AS Twitter.Retweet.Count
FROM [**DATASET_NAME_OMITTED**.main_table] 
WHERE
(interaction.id IS NOT NULL)
AND (interaction.created_at_timestamp IS NOT NULL)
AND (interaction.created_at_timestamp >= DATE_ADD(USEC_TO_TIMESTAMP(UTC_USEC_TO_HOUR(NOW())), -1, "DAY"))
AND (interaction.created_at_timestamp < USEC_TO_TIMESTAMP(UTC_USEC_TO_HOUR(NOW())))

选择
interaction.id作为interaction.id，
interaction.author.name作为interaction.author.name，
interaction.author.username作为interaction.author.username，
interaction.content作为interaction.content，
interaction.created_at_时间戳作为interaction.created_at_时间戳，
klout.得分为klout.得分，
twitter.geo.latitude作为twitter.geo.latitude，
twitter.geo.longitude作为twitter.geo.longitude，
twitter.media.expanded_url，
twitter.media.type作为twitter.media.type，
twitter.place.country作为twitter.place.country，
twitter.user.followers\u计数，
twitter.user.friends\u计数，
twitter.user.listed_count，
twitter.retweet.count计算为twitter.retweet.count
从[**数据集\u名称\u省略**.main\u表]
哪里
（interaction.id不为空）
和（interaction.created_at_timestamp不为空）
和（interaction.created_at_timestamp>=DATE_ADD（USEC_TO_timestamp（UTC_USEC_TO_HOUR（NOW（）），-1，“DAY”））
和（interaction.created_at_timestamp

---

看起来真正奇怪的是，什么会起作用，什么不会起作用之间没有模式。

twitter.user.*

字段是整数，但不接受别名，但是整数字段

klout.score

字段确实接受整数。

感谢您对此进行研究并缩小问题范围。我的别名不是一成不变的，因此这对我来说不是一个完全停止的问题。不过，最好让谷歌的人来看看，让我们知道潜在的问题是什么。
