NTILE
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The NTILE window function allows for dividing a window into N buckets of equal size (e.g. when N = 4, then you'll get quartiles), and computes the bucket number for each row.
For example:
SELECT ID, ntile(2) OVER (ORDER BY ID) FROM BOOK;
create.select(
BOOK.ID,
ntile(2).over(orderBy(BOOK.ID)))
.from(BOOK)
.fetch();
Producing:
+----+-------+ | id | ntile | +----+-------+ | 1 | 1 | | 2 | 1 | | 3 | 2 | | 4 | 2 | +----+-------+
