MYSQL 品牌按产品数量列出顺序，但是

Question

我有两张 table 。像这样；

<小时/>

Products table

id | brand | bla bla bla

<小时/>

Priority table

id | brand

<小时/>

我正在列出从产品表中选择不同的品牌 BY ORDERING 产品数量，如下所示；

SELECT DISTINCT brand as bra, (SELECT COUNT(id) FROM Products WHERE brand = bra) as cnt FROM Products ORDER BY cnt DESC

结果是:

1. 一个品牌(65 款产品)
2. B 品牌(43 个产品)
3. C 品牌(23 个产品)
4. D 品牌(17 个产品)

这是一条完美的工作线。但我想优先考虑一些品牌。位于列表顶部。

像这样:

1. S 品牌(22 个产品)
2. X 品牌(4 个产品)
3. 一个品牌(65 款产品)
4. B 品牌(43 个产品)
5. C 品牌(23 个产品)
6. D 品牌(17 个产品)

我用过这条线。但没有成功。

SELECT DISTINCT brand as bra, (SELECT COUNT(id) FROM Products WHERE brand = bra) as cnt, , (SELECT brand FROM Priority) as prior FROM Products ORDER BY prior ASC,cnt DESC

什么是真线？谢谢...

---编辑--- 完整答案是:

SELECT p.brand as bra, count(p.id) as cnt
FROM products p
GROUP BY bra
ORDER BY bra IN (SELECT pri.brand FROM priority pri ORDER BY pri.brand ASC) DESC, mark ASC

Answer 1

使用这个:

ORDER BY bra IN (SELECT brand FROM Priority) DESC, cnt DESC
