Question

我有一个查询可以获得当天的总销售数据

SELECT 
    SUM(cso.SubTotal) - (
        SELECT SUM(cso.CreditAvailable) / 1.1 
        FROM dbo.CustomerCredit cso 
        WHERE CONVERT(VARCHAR(10), cso.DateCreated, 102) = CONVERT(VARCHAR(10), SYSDATETIME(), 102)
    ) AS total_value 
FROM dbo.CustomerInvoice cso 
WHERE
    Convert(VARCHAR(10), cso.InvoiceDate, 102) = Convert(VARCHAR(10), SYSDATETIME(), 102)

我现在需要的是一张表格，其中列出了左栏目前当月的所有日期，右栏则列出了每个日期的总销售额（使用上述查询）

+---------+---------+
|  date   |  total  |
+---------+---------+
| 1/2/16  | 256232  |
| 2/2/16  | 285632  |
| 3/2/16  | 265231  |
| 4/2/16  | 254215  |
| 5/2/16  |    0    |
| ....... |  .....  |
| 28/2/16 |    0    |
| 29/2/16 |    0    |
+-------------------+

将来或周末日期的日期零销售额无关紧要。

我绞尽脑汁寻求解决方案，但由于我不熟悉SQL，我决定联系社区。

Answer 1

首先，我相信您的查询可以写成：

SELECT
    SUM(SubTotal) - (SUM(CreditAvailable) / 1.1) AS total
FROM dbo.CustomerInvoice
WHERE CAST(InvoiceDate AS DATE) = CAST(SYSDATETIME() AS DATE)

要获取每个日期的总计，只需添加GROUP BY：

即可

SELECT
    SUM(SubTotal) - (SUM(CreditAvailable) / 1.1) AS total
FROM dbo.CustomerInvoice
GROUP BY CAST(InvoiceDate AS DATE)

现在，要包含所有日期，即使是总计为0的日期，您也必须使用tally table。

DECLARE @fromDate AS DATE   = '20160101',
        @toDate AS DATE     = '20160131'

;WITH E1(N) AS(
    SELECT 1 FROM(VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))t(N)
),
E2(N) AS(SELECT 1 FROM E1 a CROSS JOIN E1 b),
E4(N) AS(SELECT 1 FROM E2 a CROSS JOIN E2 b), 
CteTally(N) AS(
    SELECT TOP(DATEDIFF(DAY, @fromDate, @toDate) + 1) ROW_NUMBER() OVER(ORDER BY(SELECT NULL))
    FROM E4
),
CteDates(dt) AS(
    SELECT DATEADD(DAY, N - 1, @fromDate) FROM CteTally
)
SELECT
    d.dt, t.total
FROM CteDates d
LEFT JOIN (
    SELECT
        dt = CAST(InvoiceDate AS DATE),
        total = SUM(SubTotal) - (SUM(CreditAvailable) / 1.1)
    FROM dbo.CustomerInvoice
    WHERE InvoiceDate >= @fromDate AND InvoiceDate < DATEADD(DAY, 1, @toDate)
    GROUP BY CAST(InvoiceDate AS DATE)
) t
    ON t.dt = d.dt

Answer 2

您可以使用以下查询：

;with date_cur_month as(
select convert(datetime, convert(varchar(6), getdate(), 112) + '01', 112) as dt
union all
select dateadd(day, 1, dt) as dt
  from date_cur_month
  where datepart(month, dateadd(day, 1, dt)) = datepart(month, getdate()))

select convert(nvarchar(8), d.dt, 3) as date
     , isnull(sum(ci.SubTotal), 0) 
     - isnull((select sum(cc.CreditAvailable) / 1.1 
                 from dbo.CustomerCredit cc
                 where cast(cc.DateCreated as date) = d.dt
              ), 0) as total 
  from dbo.CustomerInvoice ci 
    right outer join date_cur_month d on cast(ci.InvoiceDate as date) = d.dt
  group by d.dt

WITH cteRange
AS (SELECT
        DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0) AS Start_Date
    UNION ALL
    SELECT
        DATEADD(DAY, 1, cteRange.Start_Date)
    FROM cteRange
    WHERE cteRange.Start_Date < DATEADD(DAY, -1, DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()) + 1, 0))
    )
SELECT
    cteRange.Start_Date, ISNULL(inv.SubTotal,0), ISNULL(crd.CredAvail,0)
  , ISNULL(inv.SubTotal,0) - ISNULL(crd.CredAvail / 1.1,0) AS total
FROM cteRange
LEFT JOIN (SELECT
            CAST(cc.DateCreated AS date) AS DateCreated
          , SUM(cc.CreditAvailable) AS CredAvail
        FROM dbo.CustomerCredit AS cc
        WHERE cc.DateCreated >= DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)
        GROUP BY CAST(cc.DateCreated AS date)
        ) AS crd ON cteRange.Start_Date = crd.DateCreated
LEFT JOIN (SELECT
            CAST(cso.InvoiceDate AS date) AS InvoiceDate
          , SUM(cso.SubTotal) As SubTotal
        FROM dbo.CustomerInvoice AS cso
        WHERE cso.InvoiceDate >= DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)
        GROUP BY CAST(cso.InvoiceDate AS date)
        ) AS inv ON cteRange.Start_Date = inv.InvoiceDate
;

此计算返回当前月份的第一天：DATEADD(MONTH, DATEDIFF(MONTH, 0, GETDATE()), 0)然后＆＃34;递归公用表表达式＆＃34; （CTE）在当月的所有有效日期为该日期添加一天。所以我们最终得到了一个月的一组行。然后我们使用左连接到您的财务数据。

对于所涉及的两个表中的每一个，我们总结了当前月份中允许联接发生的任何数据。

请注意，为了获得日期/时间信息的最佳效果，您应尽量避免将这些信息转换为varchars。
