Question

我刚开始使用Firebase-analytics来使用BigQuery，并尝试使用自定义参数从创建的事件中获取数据。

在第13行出现错误 UNNEST（user_dim.user_properties）user_properties 错误：无法识别的名称：user_dim；您是说user_id吗？

我尝试使用提到的代码。

SELECT
  user_properties.value.value.string_value AS total_price,
  AVG((
    SELECT
      SUM(value.string_value)
    FROM
      UNNEST(event_dim),
      UNNEST(params)
    WHERE
      key = "quantity")) AS quantity
FROM
  `uniorder-prod.analytics_200255431.events_*` t,
  UNNEST(user_dim.user_properties) user_properties
WHERE
  event_name = "total_consumption_res"
  AND user_properties.key = "total_price"

我希望有2列，一列为total_price，另一列为数量，这将包含所有数量数据。

关于如何解决此问题的任何想法？

Answer 1

您的查询似乎是针对旧数据库架构创建的，此后它已经被扁平化，因此您不再需要取消嵌套user_dim（或event_dim）来访问user_properties。

我做错了，所以如果您想得到结果，可以参考此答案。

//Query to run on BigQuery Console, you can change event param as per your 
//need

SELECT
  param2.value.string_value AS item_name,
  SUM(param3.value.double_value) AS quantity,
  SUM(param4.value.double_value) AS total_price
FROM
  `uniorder-prod.analytics_200255431.events_*`,
  UNNEST(event_params) AS param1,
  UNNEST(event_params) AS param2,
  UNNEST(event_params) AS param3,
  UNNEST(event_params) AS param4
WHERE
  event_name = "total_consumption_res"
  AND param1.key = "user_id"
  AND param1.value.int_value = 118
  AND param2.key = "item_name"
  AND param3.key = "quantity"
  AND param4.key = "total_price"
GROUP BY
  item_name
ORDER BY
  total_price DESC
