就一个查询而言,如果其结果中的某些行未充分汇总(汇总是为了保护最终用户的隐私),或者未通过广告数据中心的其他隐私权检查,系统将舍弃这些行。您可以在分析查询中配置被滤除的行摘要,这样就会返回一个包含常量和被舍弃行总和的行。这有助于防止数据合计值(例如总展示次数或总点击次数)出现不一致。对于使用界面创建的新分析查询,系统会默认启用“被滤除的行摘要”。“被滤除的行摘要”不适用于受众群体查询。默认情况下,使用 API 创建的查询不会启用“被滤除的行摘要”。

They include sums from filtered rows and constants for identification. Automatic mode configures these summaries by default in the UI, adjusting as the query changes. Manual mode allows custom configuration of columns to aggregate and constants to label the summary. When using multiple tables in a query, filtered row summaries can be defined directly within the table creation. Using noise injection is recommended instead of difference checks.\n"]]
