If an INT has a fixed range, then what is the point of giving it scale? As in, "int(12)".
That's not a scale. For integer types, it's a display width. It has nothing to do with the allowable range of the underlying data type.
http://www.mysql.com/doc/en/Numeric_types.html
In Oracle, a NUMBER(12) indicates how many digits you could have (in this case, 99999999999 would be the max value).
Would an int(2) allow -99 to 99, or -2147483648 to 2147483647?
Maybe MySQL should throw an error if someone tries to create an int(xyz) column that exceeds the size of an int?

Use a larger numeric type.
