尝试解决 Coursera 问题，但不断出现语法错误

Question

我尝试在 Bigquery 中完成此查询，但仍然出现语法错误。我究竟做错了什么？？？我查看了其他解决方案，但找不到为什么我无法运行查询。

WITH longest_used_bike AS 
(
    SELECT 
        bikeid,
        SUM(duration_minutes) AS trip_duration
    FROM
        bigquery-public-data.austin_bikeshare.bikeshare_trips
    GROUP BY
        bikeid
    ORDER BY
        trip_duration DESC
    LIMIT 1 
)

Answer 1

也许第二次选择会消耗你的 cte 并在外面限制 1 :

 WITH longest_used_bike AS
    (
      SELECT 
        bike_id,
        SUM(duration_minutes) AS trip_duration
      FROM 
        `bigquery-public-data.austin_bikeshare.bikeshare_trips` 
      GROUP BY
        bike_id
    )
    SELECT *
    FROM longest_used_bike
    ORDER BY trip_duration DESC
    LIMIT 1;
