Example​

Creating a Table and Inserting Sample Data

Let's create a table named "sales" and insert some sample data:

CREATE TABLE sales (
  id INTEGER,
  product VARCHAR(50),
  price FLOAT
);

INSERT INTO sales (id, product, price)
VALUES (1, 'Product A', 10.5),
       (2, 'Product B', 20.75),
       (3, 'Product C', 30.0),
       (4, 'Product D', 15.25),
       (5, 'Product E', 25.5);

Query: Using ARG_MAX() Function

Now, let's use the ARG_MAX() function to find the product that has the maximum price:

SELECT ARG_MAX(product, price) AS max_price_product
FROM sales;

The result should look like this:

| max_price_product |
| ----------------- |
| Product C         |
