each other.

Can I set Primary key without Auto_increment ids? mysql share|improve http://stackoverflow.com/questions/25483798/error-1062-23000-duplicate-entry-for-key-primary this question asked Aug 25 '14 at 10:24 Arghya Adhya 11 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote You have more than one entry in your table vith id blank. you should chnage your id's so that they are unique and than you add add a primary key constraint. share|improve this answer answered Aug 25 '14 at 10:27 Jens 37.3k112848 add a comment| up vote 0 down vote This is not a problem of auto_increment. You have two or more rows with the same value in this column. Therefore this column can not be used as primary key. It needs to be unique. Remove redundant data or introduce another column as primary key, maybe an auto_increment column? ;) share|improve this answer answered Aug 25 '14 at 10:28 fancyPants 27.9k144259 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
