加入数据集

加入数据集后，您可以将来自查询中其他数据集的数据包含进来。 此示例使用自定义操作系统数据集将 operatingsystemID 该值映 operatingsystem 射到。

数据集:

• your_analytics_table
• custom_operating_system_lookup

按页 SELECT 面视图数为前50个操作系统创建一个语句。

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;
