Applies to ✅ Open Source Edition ✅ Express Edition ✅ Professional Edition ✅ Enterprise Edition
The NTH_VALUE window function allows for getting the value of an expression evaluated on the Nth row of the window.
SELECT ID, nth_value(ID, 2) OVER (ORDER BY ID), nth_value(ID, 2) OVER (ORDER BY ID ROWS 2 PRECEDING) FROM BOOK;
create.select(
BOOK.ID,
nthValue(BOOK.ID, 2).over(orderBy(BOOK.ID)),
nthValue(BOOK.ID, 2).over(orderBy(BOOK.ID).rowsPreceding(2)))
.from(BOOK)
.fetch();
Producing:
+----+-----------+-----------+ | id | nth_value | nth_value | +----+-----------+-----------+ | 1 | | | | 2 | 2 | 2 | | 3 | 2 | 2 | | 4 | 2 | 3 | +----+-----------+-----------+
- The window frame clause is applied to
