mysql - mysql中按年、月分组时出错

Question

我有这段代码，它在在线服务器上运行正常:

SELECT
DATE(`order`.`date`) AS `dater`,
COUNT(*) AS `orders-amount`,
SUM(`order`.`price`) AS `orders-income`,
(SELECT SUM(`amount`) FROM `paypal` WHERE `paypal`.`txn_id` != 'Bonus' AND YEAR(`dater`) = YEAR(`paypal`.`posted_date`) AND MONTH(`dater`) = MONTH(`paypal`.`posted_date`)) AS `total_charge`
FROM `order`
GROUP BY YEAR(`dater`), MONTH(`dater`)
ORDER BY `dater` DESC

但是在本地主机上它给出如下错误:

#1055 - Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'panel.order.date' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

如果我使用此代码进行分组然后它可以正常工作:

GROUP BY `dater`

此错误仅出现在本地主机上，因为我在 linux Mint 上运行并安装了 apache、php、mysql 和 pypmyadmin

意思是在本地和远程服务器上使用不同的sql模式。 您应该更改模式或更新您的查询，例如:

SELECT
YEAR(ANY_VALUE(`order`.`date`)) date_year,
MONTH(ANY_VALUE(`order`.`date`)) date_month,
COUNT(*) AS `orders-amount`,
SUM(`order`.`price`) AS `orders-income`,
(SELECT SUM(`amount`) FROM `paypal` WHERE `paypal`.`txn_id` != 'Bonus' AND YEAR(ANY_VALUE(`order`.`date`)) = YEAR(`paypal`.`posted_date`) AND MONTH(ANY_VALUE(`order`.`date`)) = MONTH(`paypal`.`posted_date`)) AS `total_charge`
FROM `order`
GROUP BY date_year, date_month
