sql-server - 如何将多个表的函数结果放在一个查询中？

Question

我有两张表，例如 ONE 和 TWO，我的表更大且结构不同，但有些字段重合。

我怎样才能得到表QUERY？

我可以只用一个带有 GROUP 和 SUM 的表来完成，但是如何在 QUERY 中添加最后一列？可能吗？

SELECT Date, SUM(Apples), SUM(Oranges) FROM One
GROUP BY Date

Answer 1

SELECT one.Date, one.place, SUM(Apples), SUM(Oranges), SUM(Grapes) 
FROM One left join Two on one.place = two.place and one.date = two.date
GROUP BY one.date, one.place

将返回第一个表中的所有位置和正确的计数

Answer 2

SELECT Date, one.place, SUM(Apples), SUM(Oranges), SUM(Grapes) 
FROM One left join Two on one.place = two.place and one.[Date] = two.[Date]
GROUP BY Date
