Sql server 每月总销售额

如果您有一个带有

SALES{Customer\u ID，Price，SmallDateTime date}

的表。你如何报告每个月的销售额

SELECT Sum(Price) As Total Sales FROM SALES Group By What Having What 

---

另一个解决方案是计算月的第一天

Select DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0)
    , Sum( Price )
From Sales
Group By DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0)

试试这个

SELECT A.CAL_YEAR AS YEAR  ,A.CAL_WEEK AS WEEK,SUM(B.SUM_OF_PROFIT) as profit FROM
CALANDER A,SALES_FACT B WHERE A.DATE_ID=B.DATE_ID
GROUP BY A.CAL_YEAR,A.CAL_WEEK;

Select DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0)
    , Sum( Price )
From Sales
Group By DateAdd(d,DateDiff(d,0,[Date])-DatePart(d,[Date])+1,0)

SELECT A.CAL_YEAR AS YEAR  ,A.CAL_WEEK AS WEEK,SUM(B.SUM_OF_PROFIT) as profit FROM
CALANDER A,SALES_FACT B WHERE A.DATE_ID=B.DATE_ID
GROUP BY A.CAL_YEAR,A.CAL_WEEK;
