Lisa,

let it be varchar2 ... but the developers are not entirely right too. oracle still puts in a character to indicate that this column has a NULL value.

So, unless your storage is at premium, leave it as varchar2, because the moment you make it CHAR, the comparison semantics change when you compare that with varchar2 field and that would be an added cost for your SQLS.
