Firebase自动收集的用户属性性别数据-如何提取性别数据

Question

如何从Big Query查询Firebase自动用户属性性别。我在下面的查询中使用查询，查询是正确的，但是执行查询后，我得到结果“查询未返回任何结果”

select app_info.id,app_info.version,
event_date,event_name, 
  param1.value.string_value as category,
  param2.value.string_value as action,
  param3.value.string_value as label,
  param4.value.string_value as Gender,
  count(1) as totalevent,count( distinct user_pseudo_id ) as uniqueusers
From `Tablet_*`,
UNNEST(event_params) as param1,
UNNEST(event_params) as param2,
UNNEST(event_params) as param3,
UNNEST(user_properties) as param4
WHERE _TABLE_SUFFIX BETWEEN '20200203'  AND '20200203' 
and param2.key='action' 
and param3.key='label' 
and param4.key='Gender'
group by 1, 2, 3, 4, 5,6,7,8
order by totalevent desc   

Answer 1

1表后缀值以确认可用的日期范围：

  SELECT DISTINCT(_TABLE_SUFFIX) AS RANGE_DATES
  FROM `firebase-public-project.analytics_153293282.events_*`

2如果前一个包含日期为'20200203'的数据，请检查您的过滤器：

param2.key ='action'

param3.key ='标签'
• param4.key ='性别'

例如，我试图通过'action'进行过滤：

  SELECT event_date, param1.key
  FROM `firebase-public-project.analytics_153293282.events_*`,
  UNNEST(event_params) as param1
  where param1.key ='action' 

查询未返回结果
