Yes, you can. In case you want to sort by numbers, you need to extract numeric part, for example:

SQL

SELECT FieldName, LEFT(FieldName, 3) AS FirstPart, CONVERT(INT, RIGHT(FieldName, LEN(FieldName)-3)) AS SecondPart
FROM TableName
ORDER BY  CONVERT(INT, RIGHT(FieldName, LEN(FieldName)-3)) ASC

i am getting this error "Invalid length parameter passed to the RIGHT function."

Do you have NULL's?<br>
If yes, add WHERE statement before ORDER BY line: WHERE FieldName IS NOT NULL<br>

the above solution is Working Pakka
just Replace fieldname as code and Table name as ##table

Solution 2

SQL

Create table ##Table(id bigint identity(1,1),code nvarchar(max))

insert Into ##Table(code)values('NAS9998')
insert Into ##Table(code)values('NAS9999')
insert Into ##Table(code)values('NAS10000')

select * From ##Table order by Cast(substring(code,4,100) as bigint) ASC
