BigQuery中的动态TABLE_DATE_RANGE

Question

Is there a way of using a date variable as an argument of TABLE_DATE_RANGE() ?

I mean, my goal is to analyze the behavior of users in the next week after they've purchased.

What I try to get is something like that:

TABLE_DATE_RANGE([mydata.], 
                TIMESTAMP(purchaseDate), 
                TIMESTAMP(DATE_ADD(purchaseDate,7,'DAY')))  

where I've previously calculated ' purchaseDate ', querying a fixed period of time. This will make dynamic the queried time range for each user. I'm not sure if this approach is against the BQ structure logic.

Answer 1

TABLE_DATE_RANGE将不接受任何字段名称，至少是因为在评估时没有可用的字段名称
