Question

我这里有这个代码：

create database shop11
use shop11

create table mathang
(
       MatHangID  INT primary key not null,
       TenMatHang varchar(50),
       SoLuong    int not null,
       Price      int not null,
)

create table nhacungcap
(
       MatHangID  INT foreign key references mathang,
       TenNhaCungCap varchar(50) ,
       DiaChi        varchar(100),
       SoDienThoai   int ,
       CONSTRAINT pk_M_CC primary key (MatHangID)
)

create table khachhang
(
       KhachHangID   int not null primary key,
       TenKhachHang  varchar(50)  not null,
       [DiaChi]      varchar(100) not null,
       [SoDienThoai] varchar(50)  not null,
)

create table donhang
(
       DonHangID int references khachhang(KhachHangID),
       TenDonHang    varchar(50),
       SoLuong       int,
       CONSTRAINT pk_DHID primary key (DonHangID)
)

INSERT INTO khachhang 
VALUES ('1','TOMMY','VIETNAM','123456789'),('2','TONY','VIETNAM','987654321'),
       ('3','TOMY','VIETNAM','1234567891'),('4','JOHNNY','VIETNAM','356112789'),
       ('6','KENNY','VIETNAM','1223236789')

INSERT INTO donhang 
VALUES ('1','LAPTOP ACER',100), ('2','LAPTOP ASUS',10),
       ('3','LAPTOP MSI',5), ('4','ZENPHONE ASUS',10),
       ('5','NOTEBOOK HP',10), ('6','IPHONE',10),
       ('7','MACBOOK PRO',10)

这是我得到的错误。我怎么能修复它，以及外键的这个错误怎么样:(请帮助，谢谢

Answer 1

您正在khachhang.KhachHangID上引用khachhang.KhachHangID

值（＆＃39; 5＆＃39;，＆＃39; NOTEBOOK HP＆＃39;，10）（＆＃39; 7＆＃39;，＆＃39; MACBOOK PRO＆＃39;，10）

在khachhang牌桌上不匹配。

SQL Server错误与外键冲突
