插入 Bigquery 中的嵌套记录

Question

我正在使用 Bigquery 将嵌套记录插入 table，但最终陷入错误场景。

架构：

 FieldName                  Type          Mode
 User                       STRING       NULLABLE
 Address                    RECORD       REPEATED
 Address.Name               STRING       NULLABLE
 Address.Age                STRING       NULLABLE
 Address.Details            RECORD       NULLABLE
 Address.Details.line1      STRING       NULLABLE
 Address.Details.line2      STRING       NULLABLE

代码：

INSERT  INTO `<dataset.tablename>`(User, Address)
values('newuser',
   [STRUCT('err' as Name,'24' as Age),
   STRUCT('newerr' as Name,'25' as Age)],
   STRUCT('streetname' as line1),
   STRUCT('houseno.' as line2)
  );

使用上面的代码，我无法将值加载到 table。请帮助我了解我们如何将值传递到嵌套记录中。

Answer 1

试试下面的方法

INSERT  INTO `<dataset.tablename>`(User, Address) values(  
  'newuser', [
  STRUCT('err' as Name,'24' as Age, STRUCT('streetname' as line1, 'houseno.' as line2) as Details),
  STRUCT('newerr' as Name,'25' as Age, STRUCT('streetname' as line3, 'houseno.' as line4))
]
  );
