Execute the code (click on SQL in phpmyadmin): ALTER TABLE TableName AUTO_INCREMENT=12345; This should set the next increment value to 12345 ... if memory serves me right.... The mysql command to reset it all is truncate but this will wipe it all. I have one suggestion for table design. When creating the id column, use UNSIGNED as it does not allow for negative integers and at the same time gives you a greater range of positive integers. Like so: `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
