SQL如何根据输入的年份统计这一年每月的销售金额

Question

create table sale

(id int,

name varchar(10),

sdate datetime,

money int)

insert into sale values (1,'西瓜','2015-01-01',10)

insert into sale values (2,'香蕉','2015-01-05',20)

insert into sale values (3,'苹果','2015-02-01',60)

insert into sale values (4,'葡萄','2015-02-23',345)

insert into sale values (5,'柚子','2015-04-23',10)

insert into sale values (6,'牛奶','2015-05-12',67)

insert into sale values (7,'地瓜','2015-06-01',10)

insert into sale values (8,'土豆','2015-07-01',10)

insert into sale values (9,'土豆','2016-07-01',10)

如何根据我自己要查找的年份来显示每月的金额 ，如果某个月销售为0，就显示为0

Answer 1

SELECT SUM(money),MONTH(sdate) AS s FROM sale WHERE YEAR(sdate) = ? GROUP BY MONTH(sdate)
