This page is a quick reference checkpoint for NTH VALUE in MariaDB: behavior, syntax rules, edge cases, and a minimal example; plus the official vendor documentation.
NTH_VALUE returns the value from the nth row in the window frame.
Returns the value from the nth row of the window frame defined by the ORDER BY and frame clause
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
NTH_VALUE(expr, n) OVER (PARTITION BY ... ORDER BY ... ROWS BETWEEN ... )
SELECT NTH_VALUE(val, 2) OVER (ORDER BY val RANGE BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS second_val FROM t1
If you came here to confirm syntax, you’re done. If you came here to get better at window functions, choose your next step.
NTH VALUE is part of a bigger window-function pattern. If you want the “why”, start here: First Last Nth Value
For the authoritative spec, use the vendor docs. This page is the fast “sanity check”.
