如何在MYSQL查询中的where条件中使用循环？

Question

select * from student where roll-no in (30 to 50)

student是表名，roll_no, first_name, last_name, add是列

如何打印30到50之间的学生资料？

Answer 1

您需要使用where子句，其范围如下：

 select * from student where [roll-no] >= 30 and [roll-no] <= 50;

Answer 2

 select * from student 
 where roll-no between 30 and 50
