This page is a quick reference checkpoint for LEAD in Redshift: behavior, syntax rules, edge cases, and a minimal example; plus the official vendor documentation.
LEAD returns a value from the next row in the window partition.
No behavioral details such as default frame behavior, NULL-handling specifics, or ordering rules are described.
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
Syntax supports LEAD(value_expr[, offset[, default]]) OVER (window); offset and default are optional.
SELECT LEAD(saletime, 1) OVER (PARTITION BY seller ORDER BY saletime) AS next_sale 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.
LEAD is part of a bigger window-function pattern. If you want the “why”, start here: Lead Lag
Reading docs is useful. Writing the query correctly under pressure is the skill.
For the authoritative spec, use the vendor docs. This page is the fast “sanity check”.
