Integrity constraint violation: 1062 Duplicate entry '1' for key 'PRIMARY'

Question

I have a databse problem where i get Integrity constraint violation: 1062. I tried some things on my own but it didtn work so now i am asking you guys to see if you people can h

Answer 1

I had the same problem, and it was not the auto increment that was causing it. I changed the data type on my table ID from TINYINT(3) to INT(10). Try that. Maybe it'll help.

Answer 2

When inserting into a table with an auto increment field, the auto increment field itself should not be specified at all.

Query("INSERT INTO prod_categorie (categorieID, parentID) VALUES (?, ?)", array($chkParent, $txtParentCategorie));
                                   ^^^^^^^^^^^                    ^             ^^^^^^^^^^

Should be just

Query("INSERT INTO prod_categorie (parentID) VALUES (?)", array($txtParentCategorie));

Just added as answer from comment discussion to allow accept and finishing the question.

Answer 3

I came across this problem when using Magento 2 with the Google Experiment set to Yes. Simply shutting it off solved my page save issue. Bu ti'm still having a problem with adding catalog products it give me an error that the URL Key for the specified store already exists. and the image is not uploading even though i have correct folder permissions. Will post an update in case it helps anyone else.

Answer 4

in my case the error is:

SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY'

the solution is to Empty/Truncate all records of the table in question

The problem happens when auto-increment is disabled on the primary-key of that table or the data-type is wrong.
