列不是NULL使用Having而不是where

Question

我有一个查询，我有问题，我想 找到不同 Leaf_category_id所以我想分组操作。

如何修改此查询以替换具有的位置。并且按操作分组不为空

select Leaf_Category_id,totalOrders,totalCartAdditions,clicks,clicks * 100/ t.s as `click_percent`
from leafCategoryAnalysis 
CROSS JOIN (SELECT SUM(clicks) AS s FROM leafCategoryAnalysis) t 
where Leaf_Category_id is not NULL
order by clicks

Answer 1

select Leaf_Category_id,sum(totalOrders),sum(totalCartAdditions),sum(clicks),sum(clicks) * 100/ sum(t.s) as `click_percent`
from leafCategoryAnalysis 
CROSS JOIN (SELECT SUM(clicks) AS s FROM leafCategoryAnalysis) t 
where Leaf_Category_id is not NULL
group by Leaf_Category_id

试试这个。我没有试过自己。希望能帮助到你。 我只是在其他列上应用了sum函数。
