This page is a quick reference checkpoint for AVG OVER in SQLite: behavior, syntax rules, edge cases, and a minimal example; plus the official vendor documentation.
AVG OVER returns the average value of an expression across the window frame.
Follows SQLite.s standard window-processing rules; aggregate windows use default frame RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW when ORDER BY is present unless overridden
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
Uses standard aggregate window syntax: AVG(expr) OVER ([PARTITION BY ..] [ORDER BY ...] [frame])
SELECT dept, AVG(salary) OVER (PARTITION BY dept) AS avg_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.
AVG OVER is part of a bigger window-function pattern. If you want the “why”, start here: Aggregate Window Functions
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”.
