显示表结构。否则您的查询是完美的....这里是一个例子：select category_id， sum（cas当category_id = 2 then product_min_price else 0 end）as ss， sum（case category_id = 1 then product_min_price else 0 end）as ttt from myzf.products –

试试这将可以帮助你，

SELECT store.date, store.pic, owner.name,SUM(store.price) AS total_price 
FROM store 
JOIN OWNER ON store.pic = owner.name 
GROUP BY store.date

我不明白，为什么你在查询

使用case语句
