希望有人可以帮助我。我有一个错误 “ SQL71501 :: ::外键:[dbo]。[FK_AddressBook_Country]对列[dbo]。[AddressBook]。[CountryID]有未解决的引用。 红线标记为[[CountryID)]。我找不到它的错。实际上,我关注了该站点http://demo.dotnetawesome.com/mvc/mycontactbook/part2,只是更改了表格。希望有人可以帮助我。非常感谢!
CREATE TABLE [dbo].[AddressBook] (
[Id] INT NOT NULL,
[Name] VARCHAR (50) NOT NULL,
[Surname] VARCHAR (50) NOT NULL,
[Address1] VARCHAR (200) NOT NULL,
[Address2] VARCHAR (100) NULL,
[Postcode] VARCHAR (6) NOT NULL,
[Town] VARCHAR (20) NOT NULL,
[Country] VARCHAR (50) NOT NULL,
[Email] VARCHAR (50) NOT NULL,
[MobileNumber] VARCHAR (20) NOT NULL,
[PictureUser] VARCHAR (200) NULL,
PRIMARY KEY CLUSTERED ([Id] ASC),
CONSTRAINT [FK_AddressBook_Country] FOREIGN KEY ([CountryID]) REFERENCES [Country]([CountryID])
);
CREATE TABLE [dbo].[Country] (
[CountryID] INT IDENTITY (1, 1) NOT NULL,
[CountryName] VARCHAR (100) NOT NULL,
PRIMARY KEY CLUSTERED ([CountryID] ASC)
);

这应该很好用,但是无论如何首先在“ FOREIGN KEY([CountryID])”中出现两个错误,您在AdresseBook中都没有名为“ CountryId”的字段,我认为您希望将“ Country”字段作为外键adressBook中的“国家/地区”字段必须与表“国家/地区”的CountryID具有相同的类型
