SP_WASTEDSPACE will scan you tables for every column, finding out how much you're using of each column and report how much of that space allocated you're wasting. For example : if you have a varchar(255) and you're only at any given time using 20 characters
@viewtype (compact or full) - displays how much information you'd like to see.
@tablename - Which table you'd like to scan. For all tables in current database set this parameter to "alltableinfo".
