马克-to-win：

(一对多：one-to-many)

1) teacher and student.

(teacher表:两列id（主键）,name。
pupil表: 三列：id（主键）,name,tid(外键))

举例： Teacher "qixy" has two students: liyaohua,fuwenlong. Teacher "huanglaosh" has two students: mashuai,jiaxiaohu.

create table pupil(id int not null,name char(10),tid int);

create table teacher(id int not null,name char(10));

INSERT INTO pupil (id,name,tid) VALUES(1,‘liyaohua‘,1);
INSERT INTO pupil (id,name,tid) VALUES(2,‘fuwenlong‘,1);
INSERT INTO pupil (id,name,tid) VALUES(3,‘mashuai‘,2);
INSERT INTO pupil (id,name,tid) VALUES(4,‘jiaxiaohu‘,2);
