RANK in Oracle - Examples & AI Generator

RANK is a powerful analytical function in Oracle SQL for assigning unique row rankings within partitioned result sets. While understanding its Oracle-specific syntax is essential—especially for developers or analysts moving between platforms—the function’s over/partition structure can be complex. AI2sql simplifies this process, letting you convert natural-language prompts into fully formed RANK queries—no coding or memorization required. Skip the syntax and generate business-ready results in 10 seconds.

RANK Syntax in Oracle

Basic Structure

RANK() OVER (PARTITION BY column1 ORDER BY column2 [ASC|DESC])

• PARTITION BY: (optional) Groups rows for separate ranking calculations

• ORDER BY: Defines the ranking order (required)

Note: Oracle supports advanced windowing for RANK. Always specify ORDER BY for meaningful results.

RANK Examples You Can Generate Instantly

1. Rank Customers by Total Purchase Value

SELECT customer_id, SUM(amount) AS total_spent,
  RANK() OVER (ORDER BY SUM(amount) DESC) AS customer_rank
FROM orders
GROUP BY customer_id;

Quickly view your top buyers by total spending.

2. Rank Employee Sales Within Each Region

SELECT region, employee_id, SUM(sales) AS total_sales,
  RANK() OVER (PARTITION BY region ORDER BY SUM(sales) DESC) AS sales_rank
FROM sales_data
GROUP BY region, employee_id;

Identify leading sales staff per region—instantly group and rank.

3. Rank Products by Monthly Revenue

SELECT product_id, TO_CHAR(order_date, 'YYYY-MM') AS order_month, SUM(amount) AS monthly_revenue,
  RANK() OVER (PARTITION BY TO_CHAR(order_date, 'YYYY-MM') ORDER BY SUM(amount) DESC) AS product_rank
FROM orders
GROUP BY product_id, TO_CHAR(order_date, 'YYYY-MM');

Compare how products perform—and peak—month by month.
