Are you thinking mysql reuses auto-increment number? If so, your mistaken. MySQL will not reuse an auto-increment unique value. say you have an empty table with an auto-increment column. You add 5 row your next id to be used is 6. if you delete id # 2 and 3 the next id to be used will still be 6 not 2 it does not go back and fill in the holes/gaps -- Jim Lucas "Some men are born to greatness, some achieve greatness, and some have greatness thrust upon them." Twelfth Night, Act II, Scene V by William Shakespeare3. Ask yourself, "Is it important to keep the auto-increment field contiguous?"The main reason for changing it is I do currently have an option to sort by record number, although, if I add a Record number in php, but still have it sort based off of the record number stored in the database, it would still sort right, but also look right...
