错误代码:1062.重复输入'PRIMARY'

Question

所以,我的教授给了我表格将其插入数据库但是当我执行他的代码时,MySQL不断给出错误代码:1062.这是冲突表和插入:

TABLES

CREATE TABLE FABRICANTES(
COD_FABRICANTE integer NOT NULL,
NOMBRE         VARCHAR(15), 
PAIS           VARCHAR(15),
primary key (cod_fabricante)
);

CREATE TABLE ARTICULOS(
ARTICULO       VARCHAR(20)NOT NULL,
COD_FABRICANTE integer NOT NULL,
PESO           integer NOT NULL ,
CATEGORIA      VARCHAR(10) NOT NULL,
PRECIO_VENTA   integer,
PRECIO_COSTO   integer,
EXISTENCIAS    integer,
primary key (articulo,cod_fabricante),
foreign key (cod_fabricante) references Fabricantes(cod_fabricante)
);

插入:

INSERT INTO FABRICANTES VALUES(10,'CALVO', 'ESPAÑA');
INSERT INTO FABRICANTES VALUES(15,'LU', 'BELGICA');
INSERT INTO FABRICANTES VALUES(20,'BARILLA', 'ITALIA');
INSERT INTO FABRICANTES VALUES(25,'GALLO', 'ESPAÑA');

INSERT INTO ARTICULOS VALUES ('Mantequilla',30, 1, 'Segunda',450,340,200);

错误:

Error Code: 1062. Duplicate entry 'Macarrones-20' for key 'PRIMARY'

如果我删除该行给出了同样的错误,但使用'Tallarines-20'

对不起,如果有任何拼写错误.谢谢!

Answer 1

您正尝试使用相同的主键插入两行.

INSERT INTO ARTICULOS VALUES ('Tallarines',20, 2, 'Primera',120,100,100);
INSERT INTO ARTICULOS VALUES ('Tallarines',20, 1, 'Segunda',99,50,100);

您可能需要添加CATEGORIA到表的主键,ARTICULOS因为您尝试多次插入具有相同主键的多个行.

primary key (articulo,cod_fabricante, categoria)

Answer 2

第 7 行和第 8INSERT行相等。您不能输入具有相同主键的多行。请注意，您的主键是 set: (articulate, cod_fabricante)，因此任何具有相同articulate和 的行cod_fabricante都会生成错误 1062。

INSERT INTO ARTICULOS VALUES ('Tallarines',20, 2, 'Primera',120,100,100);
INSERT INTO ARTICULOS VALUES ('Tallarines',20, 1, 'Segunda',99,50,100);

删除其中一行或更改其中一行的主键。
