RANK
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
RANK assigns a series of rankings, which are different from ROW_NUMBER in that they:
- Assign the same rank to tied rows
- Skip ranks after tied rows
This works similarly as ranks in a sports event, when two athletes are ranked first, the next one is ranked third.
SELECT LANGUAGE_ID, rank() OVER (ORDER BY LANGUAGE_ID) FROM BOOK;
create.select(
BOOK.LANGUAGE_ID,
rank().over(orderBy(BOOK.LANGUAGE_ID)))
.from(BOOK)
.fetch();
Producing:
+-------------+------+ | language_id | rank | +-------------+------+ | 1 | 1 | | 1 | 1 | <-- Tied rows are both ranked first | 2 | 3 | <-- The next rank is 3 as 2 is skipped | 4 | 4 | +-------------+------+
See this article for a comparison betweenROW_NUMBER,RANK, andDENSE_RANK
