That really depends on what the real data looks like since it has to be absolutely distinct.
For example if all your numeric data is positive then a value of -1 easily identifies the "null" data. If -1 is a valid value then this doesn't work. How about 'null' for the varchar2 column?

If we replaced null by something else. What would you choose : for a varchar field ? for a numeric field ? Someone has proposed blanks for the character field but I'm not comfortable with that.
