我正在尝试执行此代码，但它说我在 row_number() 表达式中缺少一些内容，我根本无法弄清楚。
with summary as
(select s.city, length(s.city) as C_length,
row_number() over (partition by length(s.city), order by s.city)
as r1 from station s
where
length(s.city) = (SELECT min(LENGTH(s1.CITY)) FROM STATION s1)
or length(s.city) = (SELECT max(LENGTH(s2.CITY)) FROM STATION s2))
select su.city, su.C_length
from summary su;
最佳答案
partition by 子句和 order by 子句之间不应有逗号。只需删除它就可以了:
row_number() over (partition by length(s.city) order by s.city)
