Answer 1

INT has a maximum signed value of 2147483647. Any number greater than that will be truncated to that value. What you need to do is change that column to be a varchar(20) which will hold strings of up to 20 characters since bank card numbers are strings and not actually numbers (you don't do math with the). You also should remove AUTO_INCREMENT as that is not a value you will be incrementing.

Answer 2

Something to ask yourself. How did the number get that big? I did not insert 2 billion rows!

Well, possibly you 'burned' that many AUTO_INCREMENT ids. This can happen in man ways:

INSERT IGNORE ... -- when the insert is ignored (because it the row already exists)
REPLACE
IODKU

and probably others.
