only takes a minute: Sign up Mysql: Duplicate key error with autoincrement primary key up vote 0 down vote favorite I have a table 'logging' in which we log visitor history. We have 14 millions pageviews in a day, so we insert 14 million records in table in a day, and traffic is highest in afternoon. From somedays we are facing php insert auto increment the problems for duplicate key entry 'id', which according to me should not be the case, since id is autoincremented field and we are not explicitly passing id in insert query. Following are the details logging (MyISAM) ---------------------------------------- | id | int(20) | | virtual_user_id | varchar(1000) | | visited_page | varchar(255) | | /* More such columns are there */ | ---------------------------------------- Please let me know what is the problem here.

Note to self: always check for other possible locations where the table is written to. We are getting duplicate keys in a table. They are not inserted at the http://stackoverflow.com/questions/514018/what-could-cause-duplicate-ids-on-a-auto-increment-primary-key-field-mysql same time (6 hours apart).

Each and every time it has been because the table has become corrupted. If it is corrupt performing a check tables should expose the problem. You can do this by running: CHECK TABLE tbl_name If it come

My Scripts are doing following operations: insert ignore into tablename set x='a', y='b' update ignore tablename set x='a', y='b' where id = 'smthing' delete from tablename where id = 'smthing' Now after running the script when I insert something manually (insert into tablename set x='ax', y='bx') insert auto increment I get the following error: Duplicate Entry for Auto Increment Value. On check I see that Auto Increment is trying to put the highest possible value of int that MySql will support as new value even and it already exist in db. The table has two index: id+x, id+y though idk if this is related to this issue. mysql innodb duplication auto-increment share|improve this question edited Apr 30 '15 at 10:22 marc_s 5,41632743 asked Mar 1 '12 at 3:39 dragosrsupercool 204313 3 Is your title a true statement? We used to get similar reports for MS Access but in reality it would turn out that in order to generate the duplicate values the system had silently dropped the primary key constraint. If it is true that you have duplicate columns within a column with a PK constraint still in place then that is a very worrying bug in mySQL. –onedaywhen Mar 1 '12 at 8:50 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote accepted I reached the max possible value of an int column. Problem resolved by altering table and setting big int than int. The signed range of MIDINT is –8388608 to 8388607. The unsigned range is 0 to 16777215 Reference: http://help.scibit.com/mascon/masconMySQL_Field_Types.html share|improve this answer edited Apr 30 '15 at 10:22 marc_s 5,41632743 answered Mar 1 '12 at 4:30 dra
