How to generate the alphabet from ASCII codes in T-SQL

Just now I had the requirement to create a loop in SSIS, and have that loop the alphabet.
In order to facilitate that, I generated a T-SQL statement, that provides the alphabet including the Danish Æ, Ø and Å. If you don’t need these, you can leave out the latter part of the last where clause (197, 198, 216).

   1:  SELECT CHAR(number) FROM master..spt_values
   2:   WHERE
   3:      Type = 'P'
   4:      AND
   5:      ( number between 65 and 90
   6:          OR
   7:        number IN (197, 198, 216)
   8:      )

Link to an ASCII table with possible values ranging from 0 to 255.
