一.准备测试环境（创建数据库表）

1>.创建husbandsfk和wifesfk表

1 use yinzhengjie;
2 
3 create table husbandsfk(id int primary key auto_increment , hname varchar(20)) ;
4         
5 create table wifesfk(id int primary key  auto_increment , wname varchar(20) , hid int , CONSTRAINT fk_hid FOREIGN KEY (hid) references husbandsfk(id)) ;
6         
7 alter table wifesfk add constraint unq_hid unique (hid) ;
