Thanks very much - nesting The NullIF in my COALESCE does what I want.

     COALESCE(NULLIF(COLA, ' '),  '*' ) AS COLA

this also worked:

     COALESCE(NULLIF(COLA, ''),  '*' ) AS COLA

Incidentally, we have an ASCII function that returns a 0 for this value, meaning Null?

When I use the Characters function, it returns 1.
