Question

我是第一次发帖。

我一直试图弄清楚这份报告的问题。在本报告中，我想显示最近销售但未退货（+非 - 价格）的产品的序列号。

我想检查一个产品是否已被标记为已销售，如果它是最后一次销售而且最后没有返回。

这就是我的方式，我想我可能需要对它进行子查询，但我无法弄清楚第一部分。

SELECT 
    ps.serial,p.upc,p.name,so.date_sold 
FROM 
    store_orders so 
    LEFT JOIN store_order_products sop ON so.id = sop.order_id
    LEFT JOIN products p ON sop.product_id = p.id 
    LEFT JOIN product_serials ps ON ps.serial = sop.product_serial
WHERE 
    (CAST(so.date_sold AS DATE) BETWEEN '2013-4-15' AND '2013-5-15')
    AND ps.deleted = '0' AND sop.price > 0
ORDER BY 
    sop.id DESC
LIMIT 10

它返回的是最后退回的产品，而不是最后销售的产品。

`ID Serial  Price
1: 8332-83 10.00
2: 8332-83 -10.00
Dont want to see this because it was returned last, not sold last

ID Serial  Price
2: 8332-82 10.00
1: 8332-82 -10.00
This was sold last not returned so looking to see this serial`

请帮忙。提前致谢。乔

好的，感谢我自己。但对于有这类问题的其他人，请你走了。

TRIPLE NESTY，哈哈

    LEFT JOIN store_order_products sop ON so.id = sop.order_id
    LEFT JOIN products p ON sop.product_id = p.id 
    LEFT JOIN product_serials ps ON ps.serial = sop.product_serial
WHERE ps.deleted = '0' AND so.store_id = '$store_id'
ORDER BY 
    sop.id DESC
LIMIT 1000
) AS t
GROUP BY t.product_serial
) AS t2
WHERE t2.price > 0
