  1. 按日期分組統(tǒng)計(jì)總金額：

    SELECT
    DATE(transaction_date) AS transaction_date,
    SUM(amount) AS total_amount
FROM
    transactions
GROUP BY
    transaction_date;

    SELECT
    product_category,
    SUM(amount) AS total_sales_amount
FROM
    sales
GROUP BY
    product_category;

  3. 按客戶分組統(tǒng)計(jì)消費(fèi)金額：

    SELECT
    customer_id,
    SUM(amount) AS total_spent_amount
FROM
    purchases
GROUP BY
    customer_id;

  4. 按地區(qū)和產(chǎn)品類別分組統(tǒng)計(jì)銷售金額：

    SELECT
    region,
    product_category,
