How to sort these data as alphanumeric.

SELECT * FROM #table 
ORDER BY 
Name,
CASE 
    WHEN 
    patindex('%[0-9]%',substring(Name,len(Name),LEN(Name))) =1 
  THEN
        cast(substring(Name,patindex('%[0-9]%', Name),len(Name)) as int)
  END

Answer 1

The following keys should sort these in the order you want them:

• Sort by everything before the first number (if any)
• Then by the length ascending
• Then the value ascending

So:

order by left(name, patindex('%[0-9]%', name + '0') - 1),
         len(name),
         name
