Suppose nameaddress is a VARCHAR(120) field, and the application used positions 1 to 30 for name, starting address at position 31. To return address only, but limit the number of characters returned to 50 use:

   ...
   SUBSTRING (nameaddress FROM 31 FOR 50)

This returns an address of up to 50 characters.
