ROW_NUMBER Analytic Function In Oracle

Описание к видео ROW_NUMBER Analytic Function In Oracle

ROW_NUMBER Analytic Function.
If you have ever used the ROWNUM pseudocolumn, you will have an idea what the ROW_NUMBER analytic function does. It is used to assign a unique number from 1-N to the rows within a partition. At first glance this may seem similar to the RANK and DENSE_RANK analytic functions, but the ROW_NUMBER function ignores ties and always gives a unique number to each row.
