Sql 如何编写存储过程来获取月份和年份的组数据

如何创建按月份和年份分组的总计的存储过程

销售表名

year week  date      value
2008 4    2008-01-21  50
2008 5    2008-02-22  25
2008 6    2008-02-23  30

可以使用一个简单的SQL：

SELECT to_char(date,'MON-YYYY'), SUM(VALUE) FROM SALE
GROUP BY to_char(date,'MON-YYYY');

试试这个

SELECT year,MONTH(date) AS [Month], SUM(value) AS [value] FROM sale 
GROUP BY year,MONTH(date)

CREATE PROCEDURE dbo.GetTotalAmount
AS 
BEGIN
    SELECT DATEPART(YEAR, date)as [Year],
    MONTH(date) as [Month],
    SUM(Value) as [Value]
    FROM Sale 
    GROUP BY DATEPART(YEAR, date), MONTH(date) 
END

EXEC dbo.GetTotalAmount

下面是一个完整的存储过程代码，其中包含参数以及如何运行该过程的示例

CREATE PROCEDURE dbo.GetTotalByDate
(
    @StartDate datetime,
    @EndDate datetime
)
AS 
BEGIN
    SELECT S.year as [Year],
    MONTH(S.date) as [Month],
    SUM(S.Value) as [Value]
    FROM Sale S
    WHERE S.date BETWEEN @StartDate and @EndDate
    GROUP BY S.year, MONTH(S.date) 
    ORDER BY [Year], [Month] 
END


EXEC dbo.GetTotalByDate @StartDate = '01/01/2013', @EndDate = '01/01/2014'

试试这个

SELECT year,MONTH(date) AS [Month], SUM(value) AS [value] FROM sale 
GROUP BY year,MONTH(date)

CREATE PROCEDURE dbo.GetTotalAmount
AS 
BEGIN
    SELECT DATEPART(YEAR, date)as [Year],
    MONTH(date) as [Month],
    SUM(Value) as [Value]
    FROM Sale 
    GROUP BY DATEPART(YEAR, date), MONTH(date) 
END

EXEC dbo.GetTotalAmount
