Mysql Error 1062 Duplicate Entry For Key 1
just like you, helping each other. Join them; it only takes a minute: Sign up MySQL error - #1062 - Duplicate entry ' ' for key 2 up vote 15 down vote favorite 2 I'm trying to insert a huge list of users to a MySQL database but everytime I try I get the error: #1062 mysql error numbers - Duplicate entry '' for key 2 It gives me this because the 2nd column is blank on quite a lot of the entries, so after it's inserted one blank entry in column 2, it won't let me add another. However, when I added most of the list yesterday I didn't get this error once even though a lot of the entries I added yesterday have a blank cell in column 2 as well. Whats going on? This is the sql code to insert 1 entry. The rest follow the same format: INSERT INTO users (`id`,`title`,`firstname`,`lastname`,`company`,`address`,`city`,`county` ,`postcode`,`phone`,`mobile`,`category`,`email`,`password`,`userlevel`) VALUES ('','','John','Doe','company','Streeet','city','county' ,'postcode','phone','','category','emial@email.co.uk','',''); mysql database share|improve this question edited May 27 '11 at 14:20 Johan 48.5k16104201 asked May 27 '11 at 14:18 nutman 1611417 Wasn't an unique index added? –MatTheCat May 27 '11 at 14:20 3 Do a SHOW CREATE TABLE on that table so we can see the schema. –josh.trow May 27 '11 at 14:20 add a comment| 8 Answers 8 active oldest votes

The query should appear in the output of SHOW SLAVE STATUS\G For example, in your error it says Duplicate entry '174465' for key 'PRIMARY'. This indicates that you should look up the value 174465 in the table you are either doing an INSERT or UPDATE. If the row does exist, can you have to decide if the query halted execution will change the row's contents. If the query will simply reproduce the exact same contents, and you believe that will be the case, you can perform one of two options: OPTION 1 Skip the error, wait 5 seconds, and view the Slave Status. Here the 5 steps for Skipping an Error STOP SLAVE; SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1; START SLAVE; SELECT SLEEP(5); SHOW SLAVE STATUS\G When you view the Slave Status, here is what to expect If Seconds_Behind_Master is NULL Replication is Broken : Look for Tell-Tale Signs If Error Number is 1062 aga

This happens in order for us to be able to identify the problem and fix it, and keep the data consistent with the mater that has sent the query. You can skip 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 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 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).
