BigQuery當前活動查詢只返回一個app_id

我正在使用以下查詢來查詢我的項目上的多個表和數據集。前兩個union all工作正常，並會返回我想要的，我遇到的問題是，添加更多時不會添加任何其他內容到輸出。我認爲這是來自我的GROUP BY，但我不確定。任何幫助都會很棒。BigQuery當前活動查詢只返回一個app_id

預期結果應該是多個目標，而不只是一個。

WITH allTables AS (
SELECT 
    CONCAT(user_dim.app_info.app_id, ':', user_dim.app_info.app_platform) as app, 
    user_dim.app_info.app_instance_id AS users 
FROM `d1.app_events_intraday_*`, UNNEST(event_dim) AS event 
WHERE _TABLE_SUFFIX 
    BETWEEN '20170406' AND '20170406' 

UNION ALL 
SELECT 
    CONCAT(user_dim.app_info.app_id, ':', user_dim.app_info.app_platform) as app, 
    user_dim.app_info.app_instance_id AS users 
FROM `d1.app_events_*`, UNNEST(event_dim) AS event 
WHERE _TABLE_SUFFIX 
    BETWEEN '20170406' AND '20170406'

單獨運行的最後一塊查詢：

SELECT 
    CONCAT(user_dim.app_info.app_id, ':', user_dim.app_info.app_platform) as 
    app, 
      user_dim.app_info.app_instance_id AS users 
      FROM `d2.app_events_*`, UNNEST(event_dim) AS event 
      WHERE _TABLE_SUFFIX 
      BETWEEN '20170406' AND '20170406'
