我有一个看起来像这样的查询：

SELECT 
    *, 
    GROUP_CONCAT(DISTINCT web_order_item.od_pcode) AS items, 
    GROUP_CONCAT(DISTINCT woi_id) AS woi_ids 
    FROM web_order 
JOIN web_order_item USING(od_id) 
JOIN customer_master ON customer_master.VC_CUSTOMER_CODE = web_order.p_vendor 
LEFT JOIN production_item ON production_item.ItemID IN (GROUP_CONCAT(DISTINCT woi_id)) AND QCStatus <> 'received' 
WHERE
   web_order.od_date >= FROM_UNIXTIME(1357257600) 
   AND web_order.od_date <= FROM_UNIXTIME(1359936000) 
   AND web_order.od_id > 0 
   AND 1 
GROUP BY web_order.od_id 
ORDER BY web_order.od_id DESC

此查询引发错误

一般错误：1111 无效使用组功能

我在这里想念什么？谢谢

AND web_order.od_id > 0 
AND 1 
GROUP BY items, woi_ids 
ORDER BY web_order.od_id DESC

跳这有帮助

您正在选择完整的原始记录，然后在 web_order_item 上进行分组连接，由于 DISTINCT 属性，这将产生单行，如果有多个记录，您将在那里分组，然后再次尝试分组...无论如何，您最后分组的目的是什么？没有聚合，一个 order by 就足够了。取出 group by...或更改 group by 以在组连接之前包含所有相关项目...
