When I try to to_number a varchar2 field I get an invalid number error, I assume one of the fields is holding an alpha charater. Is there a special character that can be used in the where claus to indicate an alpha charater search i.e what can I replace the question mark with in this where claus....
Where attribute2 LIKE '%?%'
