This page is a quick reference checkpoint for LAST VALUE in Databricks SQL: 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 in the window frame; result depends on ORDER BY and window frame boundaries
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
LAST_VALUE(expr) OVER ( [PARTITION BY ...] ORDER BY ... [window_frame] )
SELECT LAST_VALUE(salary) OVER (PARTITION BY department ORDER BY hire_date ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING) AS last_salary, employee_id, salary FROM employees
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”.
