This page is a quick reference checkpoint for MIN OVER in ORACLE: behavior, syntax rules, edge cases, and a minimal example; plus the official vendor documentation.
MIN OVER returns the smallest value in the window frame.
Behavior: MIN returns the minimum value of expr; as an analytic function it returns a value per row over the defined window or partition.
If this behavior feels unintuitive, the tutorial below explains the underlying pattern step-by-step.
Syntax : MIN(expr) OVER (analytic_clause).
SELECT manager_id, last_name, hire_date, salary, MIN(salary) OVER (PARTITION BY manager_id ORDER BY hire_date RANGE UNBOUNDED PRECEDING) AS p_cmin FROM employees ORDER BY manager_id, last_name, hire_date, salary;
If you came here to confirm syntax, you’re done. If you came here to get better at window functions, choose your next step.
MIN 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”.
