MySQL错误1241：操作数应包含1列

我试图将table1中的数据插入table2

insert into table2(Name,Subject,student_id,result)
select (Name,Subject,student_id,result)
from table1;

table2的关键是student_id.

假设没有任何重复.

我收到错误：MySQL错误1241：操作数应包含1列

table2中只有四列.

解决方法:

语法错误,从select中删除().

insert into table2 (name, subject, student_id, result)
select name, subject, student_id, result
from table1;
