Split value from one field to two
...It's almost invariably a lot faster to join columns together with a simple concatenation (when you need the full name) than it is to split them apart with a character search.
If, for some reason you cannot split the field, at least put in the extra columns and use an insert/update trigger to popula...

s+=str(i)
