Google bigquery 大查询视图已经开始打破过去的工作模式，重复字段不再工作

我有很多观点，都是在这种基本结构下形成的

{ 
    "bar": "barvalue",
    "foo":[
        { "nested": "value" },
        { "nested":"value2"}
}

因此，我有如下的工作观点

select
  bar as bar,
  foo.nested as nested
flatten([table name],foo)

但在更复杂的视图中，这周已停止工作。由于旧错误，无法保存视图。无法为字段成员创建有效的输出架构。将nested重命名为foo.nested，我使用flatte解析它。还有人看到这个吗？有什么解决办法吗？我已经加载了与失败的语法完全相同的视图，因此非常确定这是一个新的功能错误

所以我认为一个特定的值现在失败了，它是这样的

                    +- scanner: record
                    |  |- scanversion: float

然后，像这样的视图由于错误而失败

SELECT
  "groups/"+email AS name,
  g.members.email AS member,
  g.members.role AS role,
  REGEXP_EXTRACT(g.members.email,r'.*@(.*)') AS domain
FROM
  FLATTEN([<projectid>:<dataset>.group],members) g
JOIN
 [<projectid>:<dataset>.organization] o
ON
  o.scanner.scanversion = g.scanner.scanversion

好的，在进一步的跟踪和错误之后，我找到了一个解决方法，可以将视图更改为这个工作

SELECT
  violation,
  name,
  parent,
  members.role as role,
  members.member as member
FROM (
  SELECT
    "Invalid group member not in %orgdescription% domains" AS violation,
    name,
    parent,
    role AS members.role,
    member AS members.member
  FROM (
    SELECT
      "groups/"+g.email AS name,
      o.name AS parent,
      g.members.role AS role,
      g.members.email AS member,
      REGEXP_EXTRACT(g.members.email,r'.*@(.*)') AS domain
    FROM
      FLATTEN([<projectid>:<dataset>.group],members) g
    JOIN
      [<projectid>:<dataset>.organizationhd] o
    ON
      o.scanner.scanversion = g.scanner.scanversion
    WHERE
      g.members.email IS NOT NULL)
  WHERE
    domain NOT IN('foo.com'))

为我工作！成功地将视图保存为“选择栏为栏”，foo.nested为“从展平[table_name]嵌套”，foo将细化示例，因为在44个视图中，只有1个视图失败，我这样做的原因比我想象的更微妙。但是，对于我已经工作了几个月的视图来说，这种情况刚刚开始发生。在您问题的底部，该视图的错误消息到底是怎么说的？作为一项建议，我建议您开始使用bigquery而不是legacy。这是一些旧代码，无法重构，这是突然出现的。这些观点已经奏效好几个月了。
