This page is a quick reference checkpoint for NTH VALUE in Redshift: 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.
No behavioral details such as default frame behavior, NULL-handling, ordering constraints, or boundary rules are described.
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
Syntax supports NTH_VALUE(value_expr, integer_expr) OVER (window); integer_expr specifies the row position.
SELECT NTH_VALUE(price, 3) OVER (ORDER BY price) AS third_val FROM products;
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”.
