牛客网sql27题不知道哪里错了

Question

select
device_id,
gender,
case
when age<20 then '20岁以下'
when age>=20 and age=<24 then '20-24岁'
when age>=25 then '25岁及以上'
else '其他'
end as age_cut
from
user_profil

有人帮我看下，我对比了讨论感觉没错，但就是报错

Answer 1

age=<24 至少要改成 age<=24吧

select
device_id,
gender,
case
when age<20 then '20岁以下'
when age>=20 and age<=24 then '20-24岁'
when age>=25 then '25岁及以上'
else '其他'
end as age_cut
