Всего продаж в месяц

Question

Я думаю, что это распространено, правда?

Если у вас есть таблица с SALES {Customer_ID, Price, SmallDateTime date}.Как вы сообщаете все продажи в месяц?

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

Спасибо

Answer 1

  SELECT YEAR(date) as SalesYear,
         MONTH(date) as SalesMonth,
         SUM(Price) AS TotalSales
    FROM Sales
GROUP BY YEAR(date), MONTH(date)
ORDER BY YEAR(date), MONTH(date)

Answer 2

SELECT CONVERT(CHAR(7), SmallDateTime, 120) as Year_Month,
       SUM(Price)
    FROM Sales
    GROUP BY CONVERT(CHAR(7), SmallDateTime, 120) 
    ORDER BY Year_Month

Answer 3

Попробуйте это

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;

Answer 4

Другим решением является подсчет первого дня месяца

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)
