我正面临这个错误

SELECT 列表表达式引用 Warehouse.warehouse_id 既不分组也不聚合在 [2:3]

我不知道是什么原因造成的，所以任何帮助将不胜感激？这发生在 \"Warehouse.warehouse_id

SELECT
    Warehouse.warehouse_id,
    CONCAT(Warehouse.state,\':\',Warehouse.warehouse_alias) AS warehouse_name,
    COUNT(Orders.order_id) AS number_of_orders,
    (SELECT COUNT(*)
     FROM warehouse_orders.Orders AS Orders) AS total_orders,
    CASE
        WHEN COUNT(Orders.order_id) / (SELECT COUNT(*) FROM warehouse_orders.Orders AS Orders) <= 0.20
            THEN \"fulfilled 0.20% of Orders\"
        WHEN COUNT(Orders.order_id) / (SELECT COUNT(*) FROM warehouse_orders.Orders AS Orders) > 0.20
             AND COUNT(Orders.order_id)/(SELECT COUNT(*) FROM warehouse_orders.Orders AS Orders) <= 0.20
            THEN \"Fulfilled 21-60% of Orders\"
        ELSE \"Fulfilled more than 60% of Orders\"
    END AS fulfillment_summary
FROM
    warehouse_orders.Warehouse As Warehouse
LEFT JOIN
    warehouse_orders.Orders AS Orders ON Orders.warehouse_id = Warehouse.warehouse_id
GROUP BY
    warehouse_name
HAVING
    COUNT(Orders.order_id > 0)

您的问题是 Warehouse.warehouse_id 包含在选择结果中，但不包含在聚合函数（如 COUNT）中或在 group by 中提及。从 SELECT 结果中将其删除，或将其添加到 GROUP BY 您可能想要： GROUP BY 仓库名称、仓库 ID

【解决方案1】：

谢谢奥卡拉姆。这解决了我的问题。我刚刚在 GROUP BY 中添加，所以那里有 2 个元素：Warehouse.warehouse_id、warehouse_name。我认为您可以尝试在您的 GROUP BY 中添加 Warehouse.warehouse_id。我认为您在查询中错过了它。
