sqlite>

(4)查看表结构
sqlite> create table students(id integer,age integer);
sqlite> .schema students
CREATE TABLE students(id integer,age integer);

(5)插入列
sqlite> alter table students add cul;
sqlite> alter table students add column sex text;
sqlite> .schema students
CREATE TABLE students(id integer,age integer,cul,sex text);

sqlite> insert into students values(1,'aa',10,'m');
sqlite> insert into students values(2,'bb',11,1,'f');
sqlite> select * from students;
