Hello!!!
Please tell me which data type is best for the counter field?
I read books, and there the whole type is somehow vaguely explained ...
What is the range of integer types? Help me please...

    Choose a positive integer type that will cover the minimum number of records. The more type you take, the more memory overhead will be. At least it can always be changed in a big way.

    For ranges and similar issues, first of all, refer to the official documentation.
