获取总自定义维度

Question

我正在尝试获取会话中使用的服装总尺寸，但出现以下错误。我该如何解决这个问题

select count(hits.product.customDimensions.value)
FROM `bigquery-public-data.google_analytics_sample.ga_sessions_xxxx`,
UNNEST(hits) AS hits,
UNNEST(hits.product) AS prod,
UNNEST(hits.product.customDimensions) AS cust

我收到以下错误

Cannot access field customDimensions on a value with type ARRAY<STRUCT<productSKU STRING, v2ProductName STRING, v2ProductCategory STRING, ...>> at [5:21]

Answer 1

试试下面

select count(cust.value)
FROM `bigquery-public-data.google_analytics_sample.ga_sessions_20170801`,
UNNEST(hits) AS hits,
UNNEST(hits.product) AS prod,
UNNEST(prod.customDimensions) AS cust
