在MySQL中，可以使用整數類型（如TINYINT、SMALLINT、MEDIUMINT、INT和BIGINT）來存儲整數值

1. 創建一個包含整數類型的表：

CREATE TABLE sales_data (
    id INT AUTO_INCREMENT PRIMARY KEY,
    product_id INT,
    quantity_sold INT,
    price_per_unit DECIMAL(10, 2)
);

2. 向表中插入數據：

INSERT INTO sales_data (product_id, quantity_sold, price_per_unit)
VALUES (1, 10, 99.99),
       (2, 5, 49.99),
       (3, 20, 199.99),
       (1, 30, 99.99),
       (2, 15, 49.99);

3. 查詢每個產品的總銷售量：

SELECT product_id, SUM(quantity_sold) as total_sales
FROM sales_data
GROUP BY product_id;

4. 查詢每個產品的平均銷售價格：

SELECT product_id, AVG(price_per_unit) as average_price
FROM sales_data
GROUP BY product_id;

5. 查詢銷售量最高的產品：

SELECT product_id, SUM(quantity_sold) as total_sales
FROM sales_data
GROUP BY product_id
ORDER BY total_sales DESC
LIMIT 1;

6. 查詢銷售額最高的產品：

SELECT product_id, SUM(quantity_sold * price_per_unit) as total_revenue
FROM sales_data
GROUP BY product_id
ORDER BY total_revenue DESC
LIMIT 1;

這些示例展示了如何使用MySQL整數類型進行簡單的數據分析。實際應用中，你可能需要根據具體需求編寫更復雜的查詢語句。
