Think of the QUALIFY clause as the secret shortcut of the SQL world. While most of us grew up nesting subqueries just to filter the results of a window function, QUALIFY lets you do it in a single step. It acts on window functions exactly how HAVING acts on GROUP BY aggregations. Why It’s a Game Changer Cleaner Code : It eliminates the "Subquery Pyramid of Doom." No more wrapping a SELECT inside a SELECT just to get the ROW_NUMBER() = 1. Logical Flow: It filters results after window functions are calculated but before the final ORDER BY and LIMIT. Performance : Engines like Snowflake, BigQuery, and Teradata can optimize the execution plan better when the filter is explicit. The Syntax in Action Instead of writing 15 lines of CTEs to find the most recent login for every user, you can simply write: SELECT user_id, login_time, device_type FROM user_logs QUALIFY ROW_NUMBER() OVER (PARTITION BY user_id ORDER BY login_time DESC) = 1;
