This page is a quick reference checkpoint for LAST VALUE in Snowflake: behavior, syntax rules, edge cases, and a minimal example; plus the official vendor documentation.
LAST_VALUE returns the last value in the window frame.
Returns the last value within the ordered window; default window frame for ranking functions is ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING if no frame specified. Supports IGNORE NULLS and RESPECT NULLS semantics.
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
LAST_VALUE( <expr> ) [ { IGNORE | RESPECT } NULLS ] OVER ( [ PARTITION BY <expr1> ] ORDER BY <expr2> [ { ASC | DESC } ] [ NULLS { FIRST | LAST } ] [ <window_frame> ] )
SELECT region, amount, LAST_VALUE(amount) OVER (PARTITION BY region ORDER BY amount ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS last_amount FROM sales;
If you came here to confirm syntax, you’re done. If you came here to get better at window functions, choose your next step.
LAST 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”.
