在1條select語句中選擇Sum和多列

Question

有沒有一種方法可以在SQL中同時選擇一列和其他列的總和？

例：

SELECT sum(a) as car,b,c FROM toys

Answer 1

怎么樣：

select sum(a) over(), b, c from toy;

或者，如果需要：

select sum(a) over(partition by b), b, c from toy;

Answer 2

嘗試添加GROUP BY

SELECT sum(a) as car,b,c FROM toys 
GROUP BY b, c

Answer 3

SELECT b,
 c,
 (SELECT sum(a) FROM toys) as 'car'
FROM toys

Answer 4

由於您沒有提供太多背景信息，因此我假設您的意思是以下其中一項：

SELECT (SELECT SUM(a) FROM Toys) as 'car', b, c FROM Toys;

要么

SELECT SUM(a) as Car, b, c FROM Toys GROUP BY b, c;
