Duplicate entry '2147483647' for key 1

Question

Strange problem I can\'t seem to get my head around. I have a table in a MySQL database with the following structure...

    CREATE TABLE IF NOT EXISTS `tblb         


        

Answer 1

2147483647 is the largest int value for mysql. Just change the type from int to bigint.

Answer 2

signed and unsigned issue

alter table tblbaseprices
modify column site_id int(10) unsigned NOT NULL;

reference - http://dev.mysql.com/doc/refman/5.0/en/numeric-type-overview.html

• make sure unsigned for foreign key (in this case could be the site_id)
• it could be caused by trigger,
• there is no int(11), the max it can go is int(10)
• there is no need to allow negative value for ID
• to be consistently using same data type for primary key

Answer 3

With you code I got this error - Unknown column 'base_price_4a' in 'field list'. It means that you are trying to insert into another table (maybe in another schema), and that table has primary key INT and AUTO_INCREMENT=2147483647.

Answer 4

you've hit the 32-bit integer limit, thus preventing the auto increment from incrementing. switching your pk to bigint with a higher column length should fix the issue.

Also, if your PK is never going to be negative, switching to an unsigned int should give you more space.

Answer 5

it's a database issue. check your phpmyadmin > your DB > structure, your primary key should be setted in "bigint", not just "int"
