WINDOW in MySQL - Examples & AI Generator

Mastering the WINDOW clause in MySQL unlocks advanced analytics—ranking, running totals, and trends within partitions—without subqueries or complex joins. But remembering the exact MySQL WINDOW syntax can be a challenge, especially when switching from other databases or working with production code. AI2sql removes the guesswork: describe the analysis you need and get production-ready WINDOW queries—no coding required and in under 10 seconds.

WINDOW Syntax in MySQL

The WINDOW clause lets you assign one or more named window definitions, making complex queries easier to read and maintain. Syntax:

SELECT column, ...,
       window_function() OVER window_name
FROM table
WINDOW window_name AS (window_specification);

• Window functions include ROW_NUMBER(), RANK(), SUM(), AVG(), etc.

• MySQL supports WINDOW in version 8.0+.

• Key difference: MySQL uses the WINDOW clause for reusable specifications, unlike some databases.
