Auto Increment error


I have a mysql database with about 180 tables. After setting up the db, I get the following error when trying to populate some of the tables with an auto increment primary key

Database Error: Duplicate entry ‘0’ for key 1

If I alter the affected table and set auto increment to one i can only insert one record and an attempt to insert a second record gives the above error. All my tables are in Innodb engine.

Any help will be appreciated.

You may have added manualy a row in the table wich is above the value of the AUTO_INCREMENT of your column.

You can modify the start of the auto-incremention :


If not be sure your auto-incremented column is you primary key column
