I was wondering what the difference between BigInt, MediumInt, and Int are... it would seem obvious that they would allow for larger n
BigInt
MediumInt
Int
I wanted to add one more point is, if you are storing a really large number like 902054990011312 then one can easily see the difference of INT(20) and BIGINT(20). It is advisable to store in BIGINT.
INT(20)
BIGINT(20)
BIGINT
