mysql按年、季度、月，统计

以下是按年、按季度和按月统计SQL查询语句：

按年统计：

SELECT
    ds.checker,
    YEAR(ds.create_time) AS settleYear,
    SUM(ds.quantity) AS quantity,
    SUM(ds.approval_price) AS approvalPrice
FROM
    data_settle ds
WHERE
    ds.delete_flag = 0
    AND ds.approval_status != 0
    AND ds.create_time BETWEEN '2021-01-01 00:00:00' AND '2023-12-31 23:59:59'
    AND ds.checker IS NOT NULL
GROUP BY
    ds.checker,
    YEAR(ds.create_time)

按季度统计：

SELECT
    ds.checker,
    YEAR(ds.create_time) AS settleYear,
    QUARTER(ds.create_time) AS settleQuarter,
    SUM(ds.quantity) AS quantity,
    SUM(ds.approval_price) AS approvalPrice
FROM
    data_settle ds
WHERE
    ds.delete_flag = 0
    AND ds.approval_status != 0
    AND ds.create_time BETWEEN '2021-01-01 00:00:00' AND '2023-12-31 23:59:59'
    AND ds.checker IS NOT NULL
GROUP BY
    ds.checker,
    YEAR(ds.create_time),
    QUARTER(ds.create_time)

按月统计：

SELECT
    ds.checker,
    YEAR(ds.create_time) AS settleYear,
    MONTH(ds.create_time) AS settleMonth,
    SUM(ds.quantity) AS quantity,
    SUM(ds.approval_price) AS approvalPrice
FROM
    data_settle ds
WHERE
    ds.delete_flag = 0
    AND ds.approval_status != 0
    AND ds.create_time BETWEEN '2021-01-01 00:00:00' AND '2023-12-31 23:59:59'
    AND ds.checker IS NOT NULL
GROUP BY
    ds.checker,
    YEAR(ds.create_time),
    MONTH(ds.create_time)

以上三个查询语句分别实现了按年、按季度和按月的统计功能。按年统计时，使用YEAR(ds.create_time)来获取年份，并在GROUP BY子句中进行相应的分组；按季度统计时，在按年的基础上，使用QUARTER(ds.create_time)来获取季度，并在GROUP BY子句中增加对季度的分组；按月统计时，使用MONTH(ds.create_time)来获取月份，并在GROUP BY子句中增加对月份的分组。希望这样的改造符合您的需求，如果还有其他方面需要改进或有疑问的地方，欢迎随时提出。
