PERCENT_RANK

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

PERCENT_RANK works like RANK, but assigns ranks between 0 and 1

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

Producing:

+-------------+--------------+
| language_id | percent_rank |
+-------------+--------------+
|           1 |            0 |
|           1 |            0 | <-- Tied rows are both ranked first
|           2 | 0.6666666667 |
|           4 |            1 |
+-------------+--------------+
