 memberid描述了订单与会员之间的关系。

创建表sql

创建表sql

-- 会员
drop table member;
CREATE TABLE member(
       id varchar2(32) default SYS_GUID() PRIMARY KEY,
       NAME VARCHAR2(20),
       nickname VARCHAR2(20),
       phoneNum VARCHAR2(20),
       email VARCHAR2(20)
);
insert into MEMBER (id, name, nickname, phonenum, email)
values (‘E61D65F673D54F68B0861025C69773DB‘, ‘张三‘, ‘小三‘, ‘18888888888‘, ‘[email protected]‘);

创建表sql

-- 旅客
drop table traveller;
CREATE TABLE traveller(
  id varchar2(32) default SYS_GUID() PRIMARY KEY,
  NAME VARCHAR2(20),
  sex VARCHAR2(20),
  phoneNum VARCHAR2(20),
  credentialsType INT,
  credentialsNum VARCHAR2(50),
  travellerType INT
)
insert into TRAVELLER (id, name, sex, phonenum, credentialstype, credentialsnum, travellertype)
values (‘3FE27DF2A4E44A6DBC5D0FE4651D3D3E‘, ‘张龙‘, ‘男‘, ‘13333333333‘, 0, ‘123456789009876543‘, 0);
insert into TRAVELLER (id, name, sex, phonenum, credentialstype, credentialsnum, travellertype)
values (‘EE7A71FB6945483FBF91543DBE851960‘, ‘张小龙‘, ‘男‘, ‘15555555555‘, 0, ‘987654321123456789‘, 1);

旅客与订单之间是多对多关系，所以我们需要一张中间表（order_traveller）来描述。

创建表sql

-- 订单与旅客中间表
drop table order_traveller;
CREATE TABLE order_traveller(
  orderId varchar2(32),
  travellerId varchar2(32),
  PRIMARY KEY (orderId,travellerId),
  FOREIGN KEY (orderId) REFERENCES orders(id),
  FOREIGN KEY (travellerId) REFERENCES traveller(id)
)

insert into ORDER_TRAVELLER (orderid, travellerid)
values (‘0E7231DC797C486290E8713CA3C6ECCC‘, ‘3FE27DF2A4E44A6DBC5D0FE4651D3D3E‘);
insert into ORDER_TRAVELLER (orderid, travellerid)
values (‘2FF351C4AC744E2092DCF08CFD314420‘, ‘3FE27DF2A4E44A6DBC5D0FE4651D3D3E‘);
insert into ORDER_TRAVELLER (orderid, travellerid)
values (‘3081770BC3984EF092D9E99760FDABDE‘, ‘EE7A71FB6945483FBF91543DBE851960‘);
insert into ORDER_TRAVELLER (orderid, travellerid)
values (‘55F9AF582D5A4DB28FB4EC3199385762‘, ‘EE7A71FB6945483FBF91543DBE851960‘);
insert into ORDER_TRAVELLER (orderid, travellerid)
values (‘5DC6A48DD4E94592AE904930EA866AFA‘, ‘3FE27DF2A4E44A6DBC5D0FE4651D3D3E‘);

insert into ORDER_TRAVELLER (orderid, travellerid)

1.订单操作-查询所有订单流程分析

2.订单操作-查询所有订单代码实现1

在数据库中创建完所需的TABLE并且insert into 必要的数据后，我们就要写DAO层的实体类。

多与多对应关系的中间表没有实体类。

在子模块heima_ssm_domain下创建以下的3个实体类：

Orders

Member

Traveller

在子模块heima_ssm_web下创建控制类OrdersController

在子模块heima_ssm_service下创建接口和实现类 IOrdersService 和 OrdersServiceImpl

在子模块heima_ssm_dao下创建 IOrdersDao接口类供mybatis框架基于注解写sql语句

3.订单操作-查询所有订单代码实现2

DAO层的接口上在 @Select注解的下一行有必要声明查询的主键。

注解＠Results ，使用这个注解来实现属性映射对应关系。
