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”。

These summaries, enabled by default in UI-created analysis queries, combine filtered rows using sums and constants. Automatic mode configures summaries dynamically, while manual mode allows custom setup via sums and constant labels. For multiple tables, `merge_type` sums values and `merge_constant` sets a value in the summary. If the resulting summary fails privacy checks, it's also filtered, but with a warning. Using noise instead of difference checks can make filtered row summary unnecessary.\n"]]
