加入資料集

加入資料集可讓您將其他資料集的資料納入查詢中。 此範例使用自訂作業系統資料集將 operatingsystemID 值對應 operatingsystem 至。

資料集:

• your_analytics_table
• custom_operating_system_lookup

依頁面 SELECT 檢視次數建立前50個作業系統的陳述式。

SELECT 
  b.operatingsystem AS OperatingSystem,
  SUM(a.web.webPageDetails.pageviews.value) AS PageViews
FROM your_analytics_table a 
     JOIN custom_operating_system_lookup b 
      ON a._experience.analytics.environment.operatingsystemID = b.operatingsystemid 
WHERE TIMESTAMP >= ('2018-01-01') AND TIMESTAMP <= ('2018-12-31')
GROUP BY OperatingSystem 
ORDER BY PageViews DESC
LIMIT 50;
