PERCENT_RANK
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The PERCENT_RANK() hypothetical set function calculates the percent rank of the hypothetical value, i.e. the relative rank from 0 to 1 (CUME_DIST produces values from 1/N to 1)
SELECT percent_rank(0) WITHIN GROUP (ORDER BY ID), percent_rank(2) WITHIN GROUP (ORDER BY ID), percent_rank(4) WITHIN GROUP (ORDER BY ID) FROM BOOK
create.select(
percentRank(val(0)).withinGroupOrderBy(BOOK.ID),
percentRank(val(2)).withinGroupOrderBy(BOOK.ID),
percentRank(val(4)).withinGroupOrderBy(BOOK.ID))
.from(BOOK)
Producing:
+-----------------+-----------------+-----------------+ | percent_rank(0) | percent_rank(2) | percent_rank(4) | +-----------------+-----------------+-----------------+ | 0.0 | 0.25 | 0.75 | +-----------------+-----------------+-----------------+
