WINDOW in Oracle - Examples & AI Generator

Understanding how to use the WINDOW function in Oracle can be challenging due to its advanced syntax and flexibility for analytics. Yet, mastering this function is vital for SQL developers and data analysts who want to deliver sophisticated calculations over dynamic sets of rows. Instead of memorizing the complex Oracle WINDOW syntax, AI2sql - AI SQL Generator lets you create production-ready WINDOW queries from natural language—no coding required, and within seconds.

WINDOW Syntax in Oracle

Oracle’s WINDOW clause refines analytic and aggregate functions by specifying how data partitions and ordering are calculated. Syntax differences between Oracle and other databases matter, especially around PARTITION BY, ORDER BY, and custom window naming.

Basic Syntax

SELECT column, 
       analytic_function(args) OVER ( [PARTITION BY expr] [ORDER BY expr] [window_frame] )
FROM   table;

• PARTITION BY: Splits data into groups for the window.

• ORDER BY: Sets calculation order within partitions.

• window_frame: Defines the subset of rows (e.g., ROWS BETWEEN).

Defining Named Windows

SELECT column,
       analytic_function(args) OVER win_name
FROM   table
WINDOW win_name AS (PARTITION BY expr ORDER BY expr ROWS n PRECEDING);

WINDOW Examples You Can Generate Instantly

FROM   product_sales;

• Compare each employee’s salary to department average:

SELECT employee_id,
       department_id,
       salary,
       AVG(salary) OVER (PARTITION BY department_id) AS dept_avg_salary
FROM   employees;
