Are you looking to get 20 or the length of a particular string in that column?
If you are looking for the maximum length (20), that should be available in
the catalogs. For the string length you can look in the string functions
section of the document. I am not sure whether or not trailing spaces are
counted in char columns. varchar makes more sense if you actually have
variable length strings.
