无法使用ARRAY类型访问Big Query中的字段 <STRUCT<hitNumber INT64, time INT64, hour INT64, …> &gt;

Question

I'm trying to run a query using Standard SQL Dialect (ie not Legacy SQL) on BigQuery. My query is:

SELECT
date, hits.referer
FROM `refresh.ga_sessions_xxxxxx*`
LIMIT 1000

But keep getting the error

Error: Cannot access field referer on a value with type 
ARRAY<STRUCT<hitNumber INT64, time INT64, hour INT64, ...>> at [2:12]

Anyone know the proper syntax?

Answer 1

if you are looking for all referers - try

SELECT date, h.referer
FROM `refresh.ga_sessions_xxxxxx*`, UNNEST(hits) as h
