Answer 1

您可以使用 BigQuery 中的 GENERATE_DATE_ARRAY 函数来实现您想要的。更具体地说：

WITH customers AS (
SELECT 123456 as customer_id,
DATE("2022-01-01") as start_date,
DATE("2022-01-03") as last_active
)

SELECT customer_id, start_date, last_active, active_ 
FROM customers, UNNEST(GENERATE_DATE_ARRAY(start_date, last_active, INTERVAL 1 DAY)) as active_
