How to avoid numeric id being out of range?

Question

C++ / C#

In my program, records are constantly created in one table, and when there are more than 10 of them, the oldest one is deleted.
What to do with the identifier on the increment, because it will jump out of the tinyint?

Answer 1

If this is about a database and an id field with a dimension of tinyint, then it's easier to remove identity altogether and assign the id yourself explicitly.

Answer 2

Id is better to do always INT.
