MySQL语句语法

Question

我遇到了这个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;

我收到此错误：

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，Mauro

Answer 1

您在这里缺少逗号：

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;
