Question

让我们假设嵌套的重复字段是Experience.Company，Experience.Months。现在，如果体验记录包含，那么＆＃34; GE＆＃34;在Experience.Company中，我想跳过整个记录。

我试过的查询是这样的：

select name, location from table_name where Experience.Company != "GE".

这显然不起作用，因为我得到了其他值的记录。

我尝试了OMIT IF，结果相同。

我还能尝试其他什么？

Answer 1

以下是BigQuery Standard SQL

#standardSQL
WITH `table_name` AS (
  SELECT 1 AS id, 'John' AS Name, 'LA' AS Location, [STRUCT<Company STRING, Months INT64>('Google', 24), ('Apple', 36)] AS Experience UNION ALL
  SELECT 2, 'Nick', 'SF', [STRUCT<Company STRING, Months INT64>('GE', 12), ('Microsoft', 48)] AS Experience UNION ALL
  SELECT 3, 'Mike', 'LV', [STRUCT<Company STRING, Months INT64>('Facebook', 24), ('Cloudera', 36)] AS Experience 
)
SELECT name, location FROM `table_name`
WHERE NOT EXISTS (SELECT 1 FROM UNNEST(Experience) WHERE Company = 'GE')

Answer 2

我指的是

BigQuery REPEATED field contains

所以查询如下：

Select column1, column2, 
sum(experience.company contains "GE") within record as matches 
from [mytable] 
having matches = 0

如何在bigquery中过滤行，其中嵌套的重复字段包含特定值？
