问题描述



然而,我不明白为什么有错误

  

每个 UNNEST 操作符合对数据进行操作。因此,您可以将数组平整为这样:

pre $ SELECT
MAX(IF(index = 1,value,NULL) )
FROM'atomic-life-148403.131256355.ga_sessions_ *',
UNNEST(hits)as hits,
UNNEST(hits.customDimensions)AS dimension1


I would like to select the custom dimension from google big.

However, I do not understand why has the error

SELECT MAX(IF(index=1, value, NULL)) FROM UNNEST(hits.customDimensions) AS dimension1

FROM 'atomic-life-148403.131256355.ga_sessions_*',  UNNEST(hits) as hits

error is :Error: Syntax error: Unexpected keyword FROM at [3:1]

解决方案

Each UNNEST operation you apply corresponds to a cross-join operation on the data. You can therefore flatten your arrays like so:

SELECT
  MAX(IF(index=1, value, NULL))
FROM 'atomic-life-148403.131256355.ga_sessions_*',
UNNEST(hits) as hits,
UNNEST(hits.customDimensions) AS dimension1
