Question

在查询Bigquery表时是否可以获取GA分析数据的所有数据。到目前为止，我能够在某些专栏文章中做到这一点，但是当我继续前进时。我得到空结果。

Answer 1

我以一种更简单的方式重写了失败的查询，其中应包括您要输出的每一列。

但是没有必要，您仍然可以列出所有列（如果出于某种原因要这样做），只需避免UNNESTing hp.customDimensions和hp.customMetrics等几列（以及可能从查询中删除的其他列））。

您将从下面的查询中看到，这些列中没有数据，并且尝试对它们进行UNNEST是您看到空结果集的原因。

FROM `bigquery-public-data.google_analytics_sample.ga_sessions_20170801`,

解决失败查询的另一种方法是更改最后一部分，如下所示。当UNNESTed列为空时，LEFT JOIN会防止结果集为空。

FROM `bigquery-public-data.google_analytics_sample.ga_sessions_20170801` 
LEFT JOIN UNNEST(customDimensions) as cd
LEFT JOIN UNNEST(hits) as h
LEFT JOIN UNNEST(h.product) as hp
LEFT JOIN UNNEST(hp.customDimensions) as hpc
LEFT JOIN UNNEST(hp.customMetrics) as hpCustomMetrics
LEFT JOIN UNNEST(h.promotion) as hpromotion
LEFT JOIN UNNEST(h.experiment) as hExperiment
LEFT JOIN UNNEST(h.customVariables) as hcustomVariables
LEFT JOIN UNNEST(h.customDimensions) as hcustomDimensions
LEFT JOIN UNNEST(h.customMetrics) as hcustomMetrics
LEFT JOIN UNNEST(h.publisher_infos) as hpublisher

BigQuery Google Analytics（分析）的所有列数据
