Mysql Duplicate Entry For Key 2
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( 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

Duplicate Entry '1' For Key 'primary' Mysql

Join them; it only error code 1062 duplicate entry for key primary takes a minute: Sign up MySQL duplicate entry error even though there is no duplicate entry up vote 5 down vote favorite 1 I am using MySQL 5.1.56, MyISAM. My table looks like this: CREATE TABLE IF NOT EXISTS `my_table` ( http://stackoverflow.com/questions/28702069/error-code-1062-duplicate-entry-primary `number` int(11) NOT NULL, `name` varchar(50) NOT NULL, `money` int(11) NOT NULL, PRIMARY KEY (`number`,`name`) ) ENGINE=MyISAM; It contains these two rows: INSERT INTO `my_table` (`number`, `name`, `money`) VALUES (1, 'S. Name', 150), (2, 'Another Name', 284); Now I am trying to insert another row: INSERT INTO `my_table` (`number`, `name`, `money`) VALUES (2, 'S. Name', 240); And MySQL just won't insert it while telling me this: #1062 - Duplicate entry '2-S. Name' for key 'PRIMARY' I really don't understand it. The http://stackoverflow.com/questions/13132535/mysql-duplicate-entry-error-even-though-there-is-no-duplicate-entry primary key is on the first two columns (both of them), so the row I am trying to insert HAS a unique primary key, doesn't it? I tried to repair the table, I tried to optimize the table, all to no avail. Also please note that I cannot change from MyISAM to InnoDB. Am I missing something or is this a bug of MySQL or MyISAM? Thanks. To summarize and point out where I think is the problem (even though there shouldn't be): Table has primary key on two columns. I am trying to insert a row with a new combination of values in these two columns, but value in column one is already in some row and value in column two is already in another row. But they are not anywhere combined, so I believe this is supposed to work and I am very confused to see that it doesn't. mysql primary-key mysql-error-1062 duplicates share|improve this question edited Oct 30 '12 at 4:32 asked Oct 30 '12 at 4:13 user1763581 1451314 Are those the exact schema and exact INSERTs?

entry ‘1' for key ‘PRIMARY'" in data migration in Magento https://gielberkers.com/fix-duplicate-entry-1-key-primary-data-migration-magento/ Tags: fix, Magento, mysql So this morning I was boggling on a data migration with Magento that kept throwing the following MySQL error: [ERROR http://forums.mysql.com/read.php?21,563690,563690 in query 5] Duplicate entry '1' for key 'PRIMARY' 1 [ERROR in query 5] Duplicate entry '1' for key 'PRIMARY' This was really puzzling me, duplicate entry since all I did was I created a database dump and tried to import it on another server. So what was going on? Well… It turns out that Magento uses a primary key with value "0" in some cases (which is bad practice). MySQL's default behaviour when inserting data in duplicate entry for auto incremental fields with value "0" is to set it to the next possible auto increment value. Which - for an empty table - is "1". The query So… if you have the following query: MySQL INSERT INTO `core_store` (`store_id`, `code`, `website_id`, `group_id`, `name`, `sort_order`, `is_active`) VALUES (0,'admin',0,0,'Admin',0,1), (1,'store1',1,1,'Store 1',0,1), (2,'store2',2,2,'Store 2',10,1), (3,'store3',3,3,'Store 3',0,1), (4,'store4',3,4,'Store 4',0,1); 1234567 INSERT INTO `core_store` (`store_id`, `code`, `website_id`, `group_id`, `name`, `sort_order`, `is_active`)VALUES(0,'admin',0,0,'Admin',0,1),(1,'store1',1,1,'Store 1',0,1),(2,'store2',2,2,'Store 2',10,1),(3,'store3',3,3,'Store 3',0,1),(4,'store4',3,4,'Store 4',0,1); MySQL will set the store_id of line 1 to "1" instead of "0", causing the importing of line 2 to fail, because there already exists a row where store_id = 1. Oh you Magento… The fix The fix is utterly simple. It's a typical example where hours of work, stress and debugging result in a one-liner that fixes it all. Make sure in your SQL-dump file to add the following line at the top: MySQL SET sql_mode='NO_AUTO_VA

New Topic Advanced Search Error "Duplicate entry for key 1", but there don't seem to be any duplicates... Posted by: Kenn Baker () Date: August 02, 2012 04:50AM I am performing a sync process on some data in a mysql database (The mysql server version is 5.0.91-log and it is running on a Linux box). I am receiving an error like "Duplicate entry '26552' for key 1" every time a certain query sequence is executed as part of a sync process I have set up. The entry number is gradually increasing each time the query fails as per "Error in query: Duplicate entry '25065' for key 1" then "Error in query: Duplicate entry '25337' for key 1", then "Error in query: Duplicate entry '25759' for key 1" ... , but other than that, the error is the same. The error is returned as a result of running the query, "INSERT INTO `mydatabase`.mytable_just_before_umd_sync SELECT * FROM `mydatabase`.mytable" I run the process via cron on an hourly basis. In order to verfify the sync process, I create some temporary copies of table/s that can be modified by the sync process. I do this using some php, as below (executeQuery(...) is basically mysql_query($query) with some error checking and logging): $tableName = "mytable_just_before_umd_sync"; $query = "DROP TABLE IF EXISTS $tableName"; $result = executeQuery($query, $tableName, __FUNCTION__, __LINE__); $query = "CREATE TABLE $tableName LIKE $table"; $result = executeQuery($query, $tableName, __FUNCTION__, __LINE__); $query = "INSERT INTO $tableName SELECT * FROM $table"; $result = executeQuery($query, $tableName, __FUNCTION__, __LINE__); mytable is as follows: CREATE TABLE `mytable` ( `id` bigint(20) unsigned NOT NULL auto_increment, `user_id` bigint(20) unsigned NOT NULL, `school_id` bigint(20) unsigned NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ROW_FORMAT=FIXED AUTO_INCREMENT=26958 ; I've checked, and there are no duplicates in mytable (couldn't really be anyhow
