我有两张桌子
表A
Custid prodid Amt1
1 10 200
2 20 300
3 10 400
4 30 300
5 20 400
6 30 200
表B
prodid Amt2
10 100
20 200
30 300
我希望通过prodid汇总所有金额组。谁能给我ansi和Tsql查询?
答案 0 :(得分:1)
SELECT a.prodid,sum(a.Amt1 + b.Amt2) as AmtSum
FROM TableA a JOIN TableB b ON (a.prodid = b.prodid)
GROUP BY a.prodid;

SELECT SUM(a.Amt1),SUM(b.Amt2)
FROM(表A作为内部联接表B AS b ON a.prodid = b.prodid)
GROUP BY a.prodid
答案 2 :(得分:0)
我相信这可以在任何地方使用:
SELECT a.Custid,a.prodid,sum(a.Amt1 + b.Amt2) as AmtSum FROM TableA a JOIN TableB b ON (a.prodid = b.prodid) GROUP BY a.Custid,a.prodid;

尝试这个...我认为如果某些产品ID不在TABLEB中,它也会起作用
SELECT a.prodid,SUM(a.Amt1),SUM(b.Amt2)
FROM TableA AS a left outer JOIN TableB AS b ON a.prodid = b.prodid
GROUP BY a.prodid
