这两行不太明白啊 大家帮我看下谢谢了
select goods_id,goods_name,cate_name,brand_name,goods_price
from tdb_goods as g
inner join tdb_goods_cates as c on g.cate_id = c.cate_id inner join tdb_goods_brands as b on g.brand_id = b.brand_id ”
如图g(tdb_goods)里面没有cate_id和brand_id啊、为什么这里还可以写g.cate_id = c.cate_id;g.brand_id = b.brand_id
谢谢了~
