CSV 导出与 SQL 输出具有不同的值

Question

在 mariadb 安装的 phpmyadmin 中，我有一个 SQL 语句

SELECT `datepaid`, SUM(`total`) FROM `tblinvoices` WHERE `status` = "paid" AND `total` > 0 GROUP BY YEAR(datepaid)*100 + MONTH(datepaid) ORDER BY `datepaid` ASC

输出符合预期，我得到了按月分组、按月排序的总计列表。最后 5 行如下所示：

2020-06-09 13:01:31    4485.56
2020-07-07 12:36:25    4519.69
2020-08-03 13:02:29    3685.26
2020-09-26 05:49:25    4371.98
2020-10-10 16:47:32    5135.75

在所有行列表的底部，我选中所有，然后单击导出（在结果下方，而不是在顶部菜单中）。

在生成的 CSV 中，最后 5 行是

"2020-06-09 13:01:31","29.00"
"2020-07-07 12:36:25","130.50"
"2020-08-03 13:02:29","99.00"
"2020-09-26 05:49:25","385.00"
"2020-10-10 16:47:32","46.20"

看起来输出包含组中的行之一，而不是组总数。

我是不是做错了什么（很可能）或者这是某种错误？

[更新]

根据来自@nbk 的信息，我找到了一个解决方案并学到了一些东西，INTO 命令

`INSERT INTO `another_table` SELECT `datepaid`, SUM(`total`) FROM `tblinvoices` WHERE `status` = "paid" AND `total` > 0 GROUP BY YEAR(datepaid)*100 + MONTH(datepaid) ORDER BY `datepaid` ASC

Answer 1

您可以使用INTO OUTFILE

喜欢

SELECT 
    `datepaid`, SUM(`total`)
FROM
    `tblinvoices`
WHERE
    `status` = 'paid' AND `total` > 0
GROUP BY YEAR(datepaid) * 100 + MONTH(datepaid)
ORDER BY `datepaid` ASC

INTO OUTFILE 'C:/tmp/cancelled_orders.csv' 
FIELDS ENCLOSED BY '"' 
TERMINATED BY ';' 
ESCAPED BY '"' 
LINES TERMINATED BY '\r\n';

根据系统配置，您必须检查文件夹
