How to add Row Number Column at the beginning of my table in SQL?

Question

select 
    CodeColumn, NameColumn, UnitCostColumn, DiscountRateColumn,
    TotalColumn, DescriptionColumn,
    row_number() over (order by CodeColumn) AS RowNumber
from 
    GoodsTable1

This is the code I use. But it adds RowNumber at the end of my table. I don't want that

Answer 1

Just move that "column" to the beginning of the select list:

SELECT ROW_NUMBER() OVER (ORDER BY CodeColumn) AS RowNumber, -- Here!
       CodeColumn,
       NameColumn,
       UnitCostColumn,
       DiscountRateColumn,
       TotalColumn,
       DescriptionColumn
FROM   GoodsTable1
