In my select statement, I need a number -- say starting from 10 -- and I need this number incremented by 1 in each row. The query returned the number each row, but these numbers are not in ascending order, because records are sorted according column code: The default order of the sorted rows is ascending, but you can also sort in descending order using the DESC keyword after the name of the column by which you want to sort: Need assistance?
