语法错误或访问冲突：1140 GROUP 列的混合 (MIN(),MAX(),COUNT(),...)

Question

SQL 错误

SQLSTATE[42000]：语法错误或访问冲突：1140 混合 没有 GROUP 列的 GROUP 列 (MIN(),MAX(),COUNT(),...) 是 如果没有 GROUP BY 子句，则非法（SQL：SELECT sum(vehicles.total_amount) 作为 TotalAmount， COALESCE(CONCAT(payment_mode.payment_name, '(', ROUND( SUM(vehicles.total_amount)*100/Total.TotalAmount, 2),'%)'),0) 为 百分比 FROM vehicles LEFT OUTER join payment_mode ON payment_mode.id = Vehicles.pay_mode_id 左外连接（选择 SUM(vehicles.total_amount) 作为 TotalAmount，来自车辆的标志）作为 Total ON Total.flag=vehicles.flag WHERE vehicle.created_at > '2020-03-25 00:01:01' 和车辆.created_at

SQL 查询

SELECT sum(vehicles.total_amount) as TotalAmount,
        COALESCE(CONCAT(payment_mode.payment_name, '(', ROUND( SUM(vehicles.total_amount)*100/Total.TotalAmount, 2),'%)'),0) as Percent
FROM `vehicles`
LEFT OUTER join payment_mode ON payment_mode.id = vehicles.pay_mode_id
LEFT OUTER JOIN (SELECT SUM(vehicles.total_amount) as TotalAmount, flag from vehicles) as Total ON Total.flag=vehicles.flag
WHERE vehicles.created_at > '$today' and vehicles.created_at < '$todays'
GROUP BY vehicles.pay_mode_id

这是我的代码，即使这段代码在 MySQL 上运行良好，但是当我放入 Laravel 时，它会显示错误。

您的子查询 (SELECT SUM(vehicles.total_amount) as TotalAmount, flag from vehicles) as Total 错误 - 将 GROUP BY flag 添加到其中：

SELECT sum(vehicles.total_amount) as TotalAmount,
        COALESCE(CONCAT(payment_mode.payment_name, '(', ROUND( SUM(vehicles.total_amount)*100/Total.TotalAmount, 2),'%)'),0) as Percent
FROM `vehicles`
LEFT OUTER join payment_mode ON payment_mode.id = vehicles.pay_mode_id
LEFT OUTER JOIN ( SELECT SUM(vehicles.total_amount) as TotalAmount, flag 
                  from vehicles
                  GROUP BY flag ) as Total ON Total.flag=vehicles.flag
WHERE vehicles.created_at > '$today' and vehicles.created_at < '$todays'
GROUP BY vehicles.pay_mode_id
