When you assign one field as a primary key you can use auto-increment attribute to that field. It generates unique identity for the row inserting a unique auto increment value. You can also reset auto increment values.
For example if a table has 5 rows and you insert another row then the automatic value for the new row would be 6.
ALTER TABLE tbl_name AUTO_INCREMENT = 5;
TRUNCATE TABLE tbl_name;
