Question

以下查询适用于MySql 5，但我的客户端有MySql 4.1.15，此查询会出现以下错误：

＃1140 - 将GROUP列（MIN（），MAX（），COUNT（），...）混合为no 如果没有GROUP BY子句
，GROUP列是非法的

升级客户端MySql版本不是BTW的选项。有人可以帮我改写这个以使用旧版本的MySql吗？

SELECT 
   Sum( room_rev + room_rev_future ) as weekly_room_rev, 
   Sum( (`food_rev`) + (`beverage_rev`)) as weekly_catering_rev,
   (SELECT min_sales_persons 
   FROM bdp_hotel_min WHERE 
   bdp_hotel_min.hotel_num = bdp_scorecard.hotel_num 
   AND UNIX_TIMESTAMP(bdp_hotel_min.`min_override_week`) 
   < UNIX_TIMESTAMP("2011-12-02 23:59:59") 
   ORDER BY bdp_hotel_min.`min_override_week` DESC LIMIT 1 ) as override_persons,
   min_sales_persons 
FROM bdp_scorecard JOIN locations ON bdp_scorecard.hotel_num = locations.hotel_num 
WHERE bdp_scorecard.hotel_num =837 AND bdp_scorecard.hotel_num = 837 
AND UNIX_TIMESTAMP(bdp_scorecard.`created_date`) >= UNIX_TIMESTAMP("2011-11-26") 
AND UNIX_TIMESTAMP(bdp_scorecard.`created_date`) < UNIX_TIMESTAMP("2011-12-02 23:59:59")

无法测试，但看起来像是错误的组合。

SELECT 
   Sum( room_rev + room_rev_future ) as weekly_room_rev, 
   Sum( (`food_rev`) + (`beverage_rev`)) as weekly_catering_rev,
   (SELECT min_sales_persons 
   FROM bdp_hotel_min WHERE 
   bdp_hotel_min.hotel_num = bdp_scorecard.hotel_num 
   AND UNIX_TIMESTAMP(bdp_hotel_min.`min_override_week`) 
   < UNIX_TIMESTAMP("2011-12-02 23:59:59") 
   ORDER BY bdp_hotel_min.`min_override_week` DESC LIMIT 1 ) as override_persons,
   min_sales_persons 
FROM bdp_scorecard JOIN locations ON bdp_scorecard.hotel_num = locations.hotel_num 
WHERE bdp_scorecard.hotel_num =837 AND bdp_scorecard.hotel_num = 837 
AND UNIX_TIMESTAMP(bdp_scorecard.`created_date`) >= UNIX_TIMESTAMP("2011-11-26") 
AND UNIX_TIMESTAMP(bdp_scorecard.`created_date`) < UNIX_TIMESTAMP("2011-12-02 23:59:59")
GROUP BY override_persons, min_sales_persons

如何让MySQL查询在MySQL 4.1.15上运行？
