为什么我得到一个缺少逗号＆＃34;错误？

Question

我写了一段SQL代码。但是有一些＆＃34;缺少逗号＆＃34;错误。我该如何解决这个问题？

insert into mark ("value number", student_id, subject_id) values(100,1,1);
insert into mark ("value number", student_id, subject_id) values(90,2,1);


SQL ERROR: 
insert into mark (value number, student_id, subject_id) values("100",1,1)
                        *
ERROR at line 1:
