ROW_NUMBER

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

ROW_NUMBER assigns a series of unique, consecutive numbers to each row in the partition.

SELECT
  LANGUAGE_ID,
  row_number() OVER (ORDER BY LANGUAGE_ID)
FROM
  BOOK;
create.select(
         BOOK.LANGUAGE_ID,
         rowNumber().over(orderBy(BOOK.LANGUAGE_ID)))
     .from(BOOK)
     .fetch();

Producing:

+-------------+------------+
| language_id | row_number |
+-------------+------------+
|           1 |          1 |
|           1 |          2 |
|           2 |          3 |
|           4 |          4 |
+-------------+------------+
