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

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.
