Question

I want to sort product by discount on certain condition

    CASE WHEN @OrderBy = 0
    THEN table.id END ASC,
    CASE WHEN @Orderby = 2
    THEN tabl         


        

Answer 1

It seems to me you need something similar to this

select * from TableName where someCondition >100
  order by
    case when @OrderBy = 'AirlineService'
      then AirlineService END desc,
    case when  @OrderBy = 'SomeMore'
      then  MyOtherColumn  end
GO

If you not have a coulmn then you can not sort with that. Please read this Microsoft Link Please keep in mind - specifies the sort order used on columns returned in a SELECT statement. Hope it helps.
