You can also sort or order by the Number of Characters in each Column you wish 
to sort by. Shown below is a sample which sorts by the first three characters 
of the First Name and by the last two characters in the name of the town.

    SELECT *
    FROM table_name
    ORDER BY LEFT(FirstName, 3) ASC, LEFT(Town, 2);
