MySQL语句语法

Question

我遇到这个 MySQL 语句的问题:

CREATE TABLE Articoli (Cod_Articolo char(10) NOT NULL,
Des_Articolo varchar(50) NOT NULL,
Cat_Articolo char(2) NOT NULL,
Ubi_Articolo char(6) NOT NULL,
PRIMARY KEY (Cod_Articolo)
FOREIGN KEY (Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB;

我收到这个错误:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that 

corresponds to your MySQL server version for the right syntax to use near 'FOREIGN KEY 

(Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTI' at line 6

我不明白为什么...

谢谢，毛罗

Answer 1

这里少了一个逗号:

PRIMARY KEY (Cod_Articolo)

试试这个:

CREATE TABLE Articoli (Cod_Articolo char(10) NOT NULL,
Des_Articolo varchar(50) NOT NULL,
Cat_Articolo char(2) NOT NULL,
Ubi_Articolo char(6) NOT NULL,
PRIMARY KEY (Cod_Articolo),
FOREIGN KEY (Cat_Articolo) REFERENCES Categorie(Cod_Categoria) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB;
