3. 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...
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
