我填的两种答案都不合适
1，select c_name, c_stu from class where c_stu>50 or c_stu<20
2，select c_name, c_stu from class where c_stu between 50 and 20

fif的视频 吧?卡皮球和卖烧烤主持的?
select c_name, c_stu from class where c_stu not(between 20 and 50)
，select c_name, c_stu from class where c_stu not( between 50 and 20)
select c_name, c_stu from class where c_stu between 20 and 50 试试反过来。你所写的查询语句都是正确的；可能是你填写时符号没用好。
select * from class where c_stu>50 or c_stu<20 group by c_name,c_stu;
