Question

美好的一天！我正在制作一个图表，我需要显示本周的所有日子以显示每周的销售额。到目前为止，我能够显示本周的所有日子，我只是在显示每周的每一天的销售时遇到了麻烦。由于数据库中没有记录一周的日子，所以TOTAL_SALES列应该都返回Null值。相反，它返回数据库中记录的总销售额。到目前为止，这是我的存储过程查询。

WITH DAYSOFTHEWEEK AS 
(
  SELECT 0 DAY
  UNION ALL
  SELECT DAY + 1 FROM DAYSOFTHEWEEK WHERE DAY < 6
)
SELECT DATEADD(DAY, DAY, DATEADD(DAY, 2-DATEPART(WEEKDAY, CONVERT (date, GETDATE())), CONVERT (date, GETDATE()))) AS DAY_OF_THE_WEEK,
		SUM([ORDER].NET_AMOUNT) AS TOTAL_SALES
    FROM DAYSOFTHEWEEK, [ORDER]
	GROUP BY DAYSOFTHEWEEK.DAY

我尝试添加此条件语句

WHERE DAYSOFTHEWEEK.DAY IN ([ORDER].ORDER_DATE)

但它会返回此错误

Operand type clash: date is incompatible with int

有人可以帮我解决这个问题吗？有没有解决过我已有的代码？提前谢谢！

Answer 1

如果没有销售，我认为您之后的SUM是当天每天NULL -- Setup some fake sales data WITH TestData(N, Order_Date, Net_Amount) AS ( SELECT 1 N, CAST(GETDATE() AS DATE) Order_Date, RAND() * 100 Net_Amount UNION ALL SELECT N+1 N, CAST(GETDATE()-N/5 AS DATE) Order_Date, RAND(CHECKSUM(NEWID())) * 100 Net_Amount FROM TestData WHERE N < 20 ) SELECT TestData.Order_Date, TestData.Net_Amount INTO #Order FROM TestData --Set the first day of the week (if required) SET DATEFIRST 7 --Sunday ;WITH Days(N,DayOfTheWeek) AS ( SELECT 1 N, DATEADD(DAY, 1-DATEPART(WEEKDAY, GETDATE()), CONVERT(DATE,GETDATE())) DayOfTheWeek UNION ALL SELECT N+1 N,DATEADD(DAY, 1, DayOfTheWeek) DayOfTheWeek FROM Days WHERE N < 7 ) SELECT d.DayOfTheWeek, SUM(Net_Amount) TotalAmount FROM Days d LEFT JOIN #Order ON d.DayOfTheWeek = Order_Date GROUP BY d.DayOfTheWeek DayOfTheWeek TotalAmount ------------ ---------------------- 2016-08-07 219.036784917497 2016-08-08 273.319570812461 2016-08-09 271.148114731087 2016-08-10 194.780039228967 2016-08-11 NULL 2016-08-12 NULL 2016-08-13 NULL的{{1}}。秘诀是将您的日期列表添加到您的数据中：

[[NSUserDefaults standarUserDefaults] setValue:@"en"] forKey:@"AppleLanguages"];
[[NSUserDefaults standarUserDefaults] synchronize];

对我来说有点复杂：获取周使用的名称，例如

SELECT DATENAME(dw,getdate())

但你确实需要这样的东西：

SELECT ProductName,Sum(Sales) From NameOfTable  GROUP BY
 DATENAME(ww,salesDate)

本周的每一天，从您的日期第一个日期开始，如果您需要其他一周的开始日期，可以使用SET DATEFIRST临时更改查询

我认为你在那里有一些销售表，你还没有向我们展示，你需要加入到那个日期，然后分组

    WITH DAYSOFTHEWEEK AS 
(
  SELECT cast(dateadd(
                        day,
                         -datepart(weekday,getdate()) + 1  , 
                        GETDATE()
                        )
            as date)  [DAY], 0 as cnt
  UNION ALL
  SELECT dateadd(day,1,[DAY]), cnt + 1  FROM DAYSOFTHEWEEK WHERE cnt < 6
)
select DAYSOFTHEWEEK.[day], SUM([ORDER].NET_AMOUNT) AS TOTAL_SALES from  daysoftheweek
                                              JOIN
                                              SalesTable on
                                   CAST(SalesTable.SalesDate date) = DAYSOFTHEWEEK.[day]
                           GROUP BY DAYSOFTHEWEEK.[day]

选择当前周的所有日期
