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 | +-------------+--------------+
