BigQuery（Google Analytics（分析）数据：在同一个'hits.hitNumber'中查询两个不同的'hits.customDimensions.index'

Question

我的目标：

如果以下两个hits.customDimensions.index和关联的hits.customDimensions.value出现在相同的hits.hitNumber中，则为该会话计数1（如果仍嵌套主查询，则每行为1个会话：]

[['hits.customDimensions.index'= 43和相关的'hits.customDimensions.value'IN（'login'，'payment'，'order'，'thankyou'）] AND ['hits.customDimensions.index'= 10，且具有关联的'hits.customDimensions.value'='checkout'[在相同hits.hitNumber]

我的问题：

我不知道如何在不具有不同WITH表的子查询中的同一hits.hitNumber中查询两个不同的hits.customDimensions.value。如果可以的话，我敢肯定，查询将非常容易且简短。由于我不知道如何在子查询中查询此用例，因此我使用了总计为5个WITH表的解决方法。 我希望能有一种查询此用例的简单方法

说明解决方法查询：

表1：查询除“问题度量”外的所有内容>

表2-3：每个表查询一个具有匹配的hits.customDimensions.value的hits.customDimensions.index，并为其过滤正确的值，sessionId和hitNumber

table4：根据日期，sessionID和hitNumber将表2与表3左连接。基本上，如果hitNumber与来自table2和table3的sessionId组合，我算1

表5：将表1与表4左连接以合并数据

有点像盗梦空间，但也许有助于记住unnest()的输入是一个数组，而输出是表行...
