如何在 BigQuery 中选择多个自定义 Firebase 事件参数? [英] How to select multiple custom Firebase event parameters in BigQuery?

问题描述

我将 Firebase 事件导出到 BigQuery，现在我尝试从某个事件中选择两个参数.这是选择一个参数的查询:

I exported Firebase events to BigQuery and now I'm trying to select two parameters from a certain event. Here is the query for selecting one parameter:

select event_dim.params.value.int_value as level_id
from [com_company_appname_ANDROID.app_events_20161210]
where event_dim.name = "level_replays_until_first_victory" and  event_dim.params.key = "level_id"

两个参数都是int值，第一个参数的名字是level_id，第二个参数是count.我想显示的是第一列中的 level_id 和第二列中的 count.

Both parameters are int values, name of the first parameter is level_id, and the second parameter is count. What I would like is to show is level_id in first column and count in second column.

推荐答案

下面将使用 BigQuery 标准 SQL

SELECT 
  (SELECT params.value.int_value FROM x.params 
                                 WHERE params.key = 'level_id') AS level_id,
  (SELECT params.value.int_value FROM x.params 
                                 WHERE params.key = 'count') AS count
FROM `com_company_appname_ANDROID.app_events_20161210`, UNNEST(event_dim) AS x
WHERE x.name  = 'level_replays_until_first_victory'
