我可以创建一个这样的SQL表吗？

Question

Create Table Movie (
    ID int not null IDENTITY(1,1) Primary Key,
    Title varchar(50),
    ReleaseDate date not null,
    Genre varchar(50),
    Price decimal(18,2),
    Rating varchar(50),
    Autors_ID int FOREIGN KEY REFERENCES Movie_Autors(Autors_ID)
)

Create Table Autors (
    ID int not null IDENTITY(1,1) Primary Key,
    Name varchar(50),
    Born date not null,
    About text,
    Movie_ID int FOREIGN KEY REFERENCES Movie_Autors(Movie_ID)
)

Create Table Movie_Autors (
    ID int not null IDENTITY(1,1) Primary Key,
    Movie_ID int FOREIGN KEY REFERENCES Movie(ID),
    Autors_ID int FOREIGN KEY REFERENCES Autors(ID),
)

Answer 1

Presumably, this is what you want:

Create Table Movie (
    ID int not null IDENTITY(1,1) Primary Key,
    Title varchar(50),
    ReleaseDate date not null,
    Genre varchar(50),
    Price decimal(18,2),
    Rating varchar(50)
);

Create Table Autors (
    ID int not null IDENTITY(1,1) Primary Key,
    Name varchar(50),
    Born date not null,
    About varchar(max)
);

Create Table Movie_Autors (
    ID int not null IDENTITY(1,1) Primary Key,
    Movie_ID int FOREIGN KEY REFERENCES Movie(ID),
    Autors_ID int FOREIGN KEY REFERENCES Autors(ID),
);

That is, you have no foreign key references in Movies or Autors , so you should not declare any.

As a note NOT NULL and PRIMARY KEY are redundant. PRIMARY KEY is sufficient.

I also changed text to varchar(max) . The text datatype has been deprecated.
