PRIMARY KEY ( `int_supr_id` ) , CONSTRAINT `fk_parent_id` FOREIGN KEY ( `int_supr_id` ) In the above statement, you can't redefine the index type

Duplicate entry 'PRIMARY' up vote 1 down vote favorite So, my professor gave me tables to insert it in a database but when I execute his code, MySQL is constantly giving the Error Code: 1062. Here is the conflict tables and the inserts: TABLES CREATE TABLE FABRICANTES( http://stackoverflow.com/questions/28702069/error-code-1062-duplicate-entry-primary 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) ); INSERT INTO: 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 FABRICANTES VALUES(30,'PRESIDENT', 'FRANCIA'); INSERT INTO ARTICULOS VALUES ('Macarrones',20, 1, 'Primera',100,98,120); INSERT INTO ARTICULOS VALUES ('Tallarines',20, 2, 'Primera',120,100,100); INSERT INTO ARTICULOS VALUES ('Tallarines',20, 1, 'Segunda',99,50,100); INSERT INTO ARTICULOS VALUES ('Macarrones',20, 1, 'Tercera',80,50,100); INSERT INTO ARTICULOS VALUES ('Atún',10, 3, 'Primera',200,150,220); INSERT INTO ARTICULOS VALUES ('Atún',10, 3, 'Segunda',150,100,220); INSERT INTO ARTICULOS VALUES ('Atún',10, 3, 'Tercera',100,50,220); INSERT INTO ARTICULOS VALUES ('Sardinillas',10, 1,'Primera',250,200,200); INSERT INTO ARTICULOS VALUES ('Sardinillas',10, 1,'Segunda',200,160,200); INSERT INTO ARTICULOS VALUES ('Sardinillas',10, 1,'Tercera',100,150,220); INSERT INTO ARTICULOS VALUES ('Mejillones',10, 1, 'Tercera',90,50,200); INSERT INTO ARTICULOS VALUES ('Mejillones',10, 1, 'Primera',200,150,300); INSERT INTO ARTICULOS VALUES ('Macarrones',25, 1, 'Primera',90,68,150); INSERT INTO ARTICULOS VALUES ('Tallarines',25, 1, 'Primera',100,90,100); INSERT INTO ARTICULOS VALUES ('Fideos',25, 1, 'Segunda',75,50,1
This happens in order for us to be able to identify the problem and fix it, and keep the data consistent http://www.ducea.com/2008/02/13/mysql-skip-duplicate-replication-errors/ with the mater that has sent the query. You can skip https://www.tutorialspoint.com/mysql/mysql-handling-duplicates.htm such errors, even if this is not recommended, as long as you know really well what are those queries and why they are failing, etc. For example you can skip just one query that is hanging the slave using: 1 mysql>SET GLOBAL SQL_SLAVE_SKIP_COUNTER=1; START SLAVE; There duplicate entry might be cases where you will want to skip more queries. For example you might want to skip all duplicate errors you might be getting (output from show slave status;): 1 "1062 | Error 'Duplicate entry 'xyz' for key 1' on query. Default database: 'db'. Query: 'INSERT INTO ..." If you are sure that skipping those errors mysql error duplicate will not bring your slave inconsistent and you want to skip them ALL, you would add to your my.cnf: 1 slave-skip-errors = 1062 As shown above in my example 1062 is the error you would want to skip, and from here we have: _ Error: 1062 SQLSTATE: 23000 (ER_DUP_ENTRY) Message: Duplicate entry ‘%s’ for key %d_ You can skip also other type of errors, but again don’t do this unless you understand very well what those queries are and what impact they have on your data: 1 slave-skip-errors=[err_code1,err_code2,...|all] and for the error codes you can see them all here … (you will see them in your _show slave statu_s; also).

Sometimes, it is allowed but sometimes it is required to stop duplicate records. Sometimes, it is required to identify duplicate records and remove them from the table. This chapter will describe how to prevent duplicate records occurring in a table and how to remove already existing duplicate records. Preventing Duplicates from Occurring in a Table: You can use a PRIMARY KEY or UNIQUE Index on a table with appropriate fields to stop duplicate records. Let's take one example: The following table contains no such index or primary key, so it would allow duplicate records for first_name and last_name. CREATE TABLE person_tbl ( first_name CHAR(20), last_name CHAR(20), sex CHAR(10) ); To prevent multiple records with the same first and last name values from being created in this table, add a PRIMARY KEY to its definition. When you do this, it's also necessary to declare the indexed columns to be NOT NULL, because a PRIMARY KEY does not allow NULL values: CREATE TABLE person_tbl ( first_name CHAR(20) NOT NULL, last_name CHAR(20) NOT NULL, sex CHAR(10), PRIMARY KEY (last_name, first_name) ); The presence of a unique index in a table normally causes an error to occur if you insert a record into the table that duplicates an existing record in the column or columns that define the index. Use INSERT IGNORE rather than INSERT. I
