This page is a quick reference checkpoint for LAST VALUE in SQLite: 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 value of expr from the last row in the window frame; affected by ORDER BY and frame - default frame may cause LAST_VALUE to return the current row unless an appropriate frame is specified
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
Syntax: LAST_VALUE(expr) OVER ([PARTITION BY ...] [ORDER BY ...] [frame])
SELECT val, LAST_VALUE(val) OVER (ORDER BY val ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS last_val FROM t;
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”.
