It is not a natural order, natural order is the one you are getting.
Easy way would be to change the table so that D and number would be in
different columns. Another way is to use some string manipulation
functions to parse string into character and a number and then order by
number. This might mean slow queries if you have many rows in your table
so first solution is better if it is possible to do.
left() right() and length() functions atleast are able to to do this.
I'm not sure if there is a better way to do it, you can look for such
functions from the manual: http://dev.mysql.com/doc/mysql/en/String_functions.html

Yea to me natural order is what bobb has described. I think I'll just
restructure the table so that the table building and unit IDs are separate.
Thanks,
