一、Modeling a Many-to-Many Relationship with No Payload

1. 创建数据库表

CREATE TABLE [Album]
(
[AlbumId] [int] NOT NULL IDENTITY(1, 1),
[AlbumName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [Album] ADD CONSTRAINT [PK_Album] PRIMARY KEY CLUSTERED  ([AlbumId]) ON [PRIMARY]
GO

CREATE TABLE [Artist]
(
[ArtistId] [int] NOT NULL IDENTITY(1, 1),
[FirstName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL,
[MiddleName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL,
[LastName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [Artist] ADD CONSTRAINT [PK_Artist] PRIMARY KEY CLUSTERED  ([ArtistId]) ON [PRIMARY]
GO

CREATE TABLE [LinkTable]
(
[ArtistId] [int] NOT NULL,
[AlbumId] [int] NOT NULL
) ON [PRIMARY]
GO
ALTER TABLE [LinkTable] ADD CONSTRAINT [PK_LinkTable] PRIMARY KEY CLUSTERED  ([ArtistId], [AlbumId]) ON [PRIMARY]
GO
ALTER TABLE [LinkTable] ADD CONSTRAINT [FK_LinkTable_Album] FOREIGN KEY ([AlbumId]) REFERENCES [Album] ([AlbumId])
GO
ALTER TABLE [LinkTable] ADD CONSTRAINT [FK_LinkTable_Artist] FOREIGN KEY ([ArtistId]) REFERENCES [Artist] ([ArtistId])
GO
