预期为“)”但在 [5:45] 得到关键字 AS

Expected ")" but got keyword AS at [5:45]

select 
usertype,
concat(start_station_name,"to", end_station_name) AS route,
COUNT(*) as num_trips,
round(avg(cast(tripduration as int64)/60,2) AS duration
from 'bigquery-public-data.new_york.citibike_trips'
group by 
start_station_name, end_station_name, usertype
order by
num_trips DESC
limit 10

忘记关闭 AVG 函数的括号:

round(avg(cast(tripduration as int64)/60),2) AS duration f

/60)

末尾的括号
