我想选择可用库存最多的自行车，即品牌库存+自行车商店库存？我该怎么做呢？这是我到目前为止所拥有的，但尚未执行。
Select model, price, rating, state, brands.brandname, brands.website,
bikebrandsellstock.size, bikebrandsellstock.brandstock, bikeshopsellbike.bikeshopname, bikeshopsellbike.size, bikeshopsellbike.bikeshopstock
from bikes
INNER JOIN brands ON bikes.model = brands.model
INNER JOIN bikebrandsellstock ON bikes.model = bikebrandsellstock.model
INNER JOIN bikeshopsellbike ON bikes.model = bikeshopsellbike.model
WHERE SUM(bikebrandsellstock.stock+bikeshopsellbike.stock)
IN (SELECT MAX(SUM(bikebrandsellstock.stock+bikeshopsellbike.stock)))
最佳答案
也许你想太多了:
SELECT *
FROM
bikebrandsellstock b
INNER JOIN
bikeshopsellbike s
ON s.model = b.model and s.size = s.size
ORDER BY b.brandstock + s.bikeshopstock DESC
LIMIT 1
关于mysql - 我该如何执行这个选择语句？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45831721/
