Problems about after deleting data from database
===

Anyone know how to solve this ID problem? 

For example : 

ID | Message
1  |  Hi
2  |  Philemon
3  |  Car              <-- Delete this row
4  |  Tay
5  |  Bye

When you delete the 3rd row, the ID after the row will auto update and fill in the ID.

ID  | Message
1   | Hi
2   | Philemon
3   | Tay
4   | Bye



Thanks !
