MEDIAN
Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The MEDIAN() aggregate function calculates the median value of all input values. MEDIAN(x) is equivalent to standard SQL PERCENTILE_CONT(0.5) WITHIN GROUP (ORDER BY x), see PERCENTILE_CONT.
SELECT median(ID) FROM BOOK
create.select(median(BOOK.ID))
.from(BOOK)
Producing:
+--------+ | median | +--------+ | 2.5 | +--------+
