hi, I have a basic doubt of SQL language structurei, look at:
bigint, int, smallint, tinyint but what is more used? varchar?
e.g: a columm with 11 numbers of identification as (CPF from Brazil) must I use int (11) or varchar (100) or another one?

Please explain more details. What's a CPF? If you have a fixed number of characters, particularly if they start with "000" char(11) might be a better format.
I agree. Here's the link:
