hi,

its not possible if datatype is nvarchar, you can use one more field as id and delcare it as int then you can use order by with query

select * from table1 order by id desc

hope this will help

Assuming that there will be space between number and character this query will work fine;

select * from tb_product
order by cast(left(SUBSYSTEM, charindex(' ',SUBSYSTEM) -1) as int) ASC
