I'm trying to create a table in a mySQL table using phpmyadmin, but am really confused.

What is the Length/Values field? If I have a data type of INT, and I put the number "2" in the Length/Values field, does that mean:

Case 1: The maximum number that can be in that column is 2 (e.g. it can be 0,1,2).

Case 2: The number can have to characters (e.g. it can be 0-99)

Case 3: This is a power of two, 2^2 = 4 and that is the highest number that can be in the table.

Obviously I am totally confused and no matter how many websites I read I can't seem to understand this field.

I would appreciate any clarification you might be able to give!!

http://php.about.com/od/learnmysql/ss/create_tables.htm step by step tutorial.

In that tutorial, the author does not define a size for the integer field. Is that correct?

So, numbers don't need to be assigned sizes, but when the type is VARCHAR then the length/values field sets the maximum number of characters?

Correct
