Question

我有一个查询，我正在剥离一些不需要的字段并在where子句中放入一个限定符。导出到excel时，除去Load Size（参见第一个查询）中的所有字段，我得到84行。在第二个查询中，我只是删除一些字段并添加限定符以除去那些负载大小为0的字段。我使用相同的参数运行它，但得到87行。我不知道删除是什么触发了这一点。原始查询：

    Declare @start Varchar(20),
            @end VarChar(20),
            @division varchar(2),
            @group varchar(20)

            set @start = '02/01/2015'
            set @end = '02/09/2015'
            set @division= '02'
            set @group  = 'anodize'

    --Get the most recent order date
SELECT
    MAX(DATEPHYSICAL) AS 'DATEPHYSICAL',
    ITEMID
INTO
    #tempOrderDates
FROM
    dbo.INVENTTRANS
GROUP BY
    ITEMID

SELECT 
    ITEMID,
    SUM(dbo.CUSTINVOICETRANS.QTY) AS 'Quanity',
    SUM(LINEAMOUNTMST) AS 'Sales',
    COUNT(DISTINCT dbo.CUSTINVOICEJOUR.SALESID) AS 'Total Orders'
INTO
    #tempItemRevenue
FROM
    dbo.CUSTINVOICEJOUR INNER JOIN 
    dbo.CUSTINVOICETRANS ON dbo.CUSTINVOICEJOUR.INVOICEID = dbo.CUSTINVOICETRANS.INVOICEID
WHERE
    dbo.CUSTINVOICETRANS.DIMENSION2_ IN (@division)
    AND
    CONVERT(DATETIME, dbo.CUSTINVOICETRANS.INVOICEDATE, 101) BETWEEN @start AND @end
GROUP BY
    ITEMID

SELECT
    ITEMGROUPID AS 'Process',
    [DESCRIPTION] AS 'Division',
    dbo.INVENTTABLE.ITEMID AS 'Item ID',
    EXTITEM AS 'Cust Item ID',
    dbo.INVENTTABLE.CUSTNAME AS 'Customer',
    cu.[SalesGroup],
    dbo.USERINFO.NAME AS 'Sales Engineer',
    cu.[Street],
    cu.[City],
    cu.[State],
    cu.[ZipCode],
    ISNULL(PRICE / CASE WHEN PRICEUNIT = 0 THEN NULL ELSE PRICEUNIT END, 0) AS 'Unit Price',
    PRICEDATE AS 'Date of Price',
    LOADQTY AS 'Load Size',
    LOADQTY * ISNULL(PRICE / CASE WHEN PRICEUNIT = 0 THEN NULL ELSE PRICEUNIT END, 0) AS 'Load Value',
    Sales,
    Quanity,
    [Total Orders],
    CEILING(ISNULL(Quanity / CASE WHEN [Total Orders] = 0 THEN NULL ELSE [Total Orders] END, 0)) AS 'Avg. Order Quanity',
    DATEPHYSICAL AS 'Last Order Date'
FROM
    dbo.INVENTTABLE INNER JOIN 
    dbo.INVENTTABLEMODULE ON dbo.INVENTTABLE.ITEMID = dbo.INVENTTABLEMODULE.ITEMID INNER JOIN 
    #tempOrderDates ON dbo.INVENTTABLE.ITEMID = #tempOrderDates.ITEMID INNER JOIN 
    #tempItemRevenue ON dbo.INVENTTABLE.ITEMID = #tempItemRevenue.ITEMID INNER JOIN 
    dbo.DIMENSIONS ON NUM = dbo.INVENTTABLE.DIMENSION2_ INNER JOIN 
    dbo.CUSTTABLE cu ON ACCOUNTNUM = CUSTACCOUNT LEFT OUTER JOIN 
    dbo.SMMSALESUNITMEMBERS ON SALESUNITID = cu.SALESGROUP AND SALESMANAGER = 1 INNER JOIN 
    dbo.USERINFO ON ID = SALESMANID
WHERE
    MODULETYPE = 2
    AND
    ITEMGROUPID IN (@group)
    AND
    dbo.INVENTTABLE.DIMENSION2_ IN (@division)

DROP TABLE #tempOrderDates
DROP TABLE #tempItemRevenue

修改后的查询摆脱了推销员的东西和客户信息：

    Declare @start Varchar(20),
        @end VarChar(20),
        @division varchar(2),
        @group varchar(20)

        set @start = '02/01/2015'
        set @end = '02/09/2015'
        set @division= '02'
        set @group  = 'anodize'



SELECT 
    ITEMID,
    SUM(dbo.CUSTINVOICETRANS.QTY) AS 'Quanity',
    SUM(LINEAMOUNTMST) AS 'Sales',
    COUNT(DISTINCT dbo.CUSTINVOICEJOUR.SALESID) AS 'Total Orders'
INTO
    #tempItemRevenue
FROM
    dbo.CUSTINVOICEJOUR INNER JOIN 
    dbo.CUSTINVOICETRANS ON dbo.CUSTINVOICEJOUR.INVOICEID = dbo.CUSTINVOICETRANS.INVOICEID
WHERE
    dbo.CUSTINVOICETRANS.DIMENSION2_ IN (@division)
    AND
    CONVERT(DATETIME, dbo.CUSTINVOICETRANS.INVOICEDATE, 101) BETWEEN @start AND @end
GROUP BY
    ITEMID

SELECT
    ITEMGROUPID AS 'Process',
    [DESCRIPTION] AS 'Division',
    LOADQTY AS 'Load Size',
    LOADQTY * ISNULL(PRICE / CASE WHEN PRICEUNIT = 0 THEN NULL ELSE PRICEUNIT END, 0) AS 'Load Value',
    Sales,
    Quanity

FROM
    dbo.INVENTTABLE 
    INNER JOIN 
    dbo.INVENTTABLEMODULE ON dbo.INVENTTABLE.ITEMID = dbo.INVENTTABLEMODULE.ITEMID 
    inner JOIN 
    #tempItemRevenue ON dbo.INVENTTABLE.ITEMID = #tempItemRevenue.ITEMID 
    INNER JOIN 
    dbo.DIMENSIONS ON NUM = dbo.INVENTTABLE.DIMENSION2_ 


WHERE
    MODULETYPE = 2
    AND
    ITEMGROUPID IN (@group)
    AND
    dbo.INVENTTABLE.DIMENSION2_ IN (@division)
    and LOADQTY >0


DROP TABLE #tempItemRevenue

我不明白缺少什么会给我带来不同的结果。我已经尝试一点一点地挑选查询，但我没有看到它在哪里中断。

Answer 1

问题很可能出在您删除的联接中。如果删除销售人员和客户表，则可能会返回这些联接正在删除的行。

我建议检查联接中的值，看看有什么区别。您可能有一些NULL或一些不存在的ID或行不存在的行：SALESMANAGER = 1。

看到分别只有84行和87行，您应该能够通过眼睛检查差异，然后检查这些记录是否有差异。

Answer 2

我认为问题是你也删除了一些INNER JOIN：这可能会导致更多的行出现。尝试删除字段，并保留第一个查询的INNER JOINS。

问候。

Answer 3

第一个查询是您加入表CUSTTABLE而第二个查询未加入。

您可能会发现3个与CUSTTABLLE表

无关的额外行

Answer 4

我差异的第一选择是删除#tempOrderDates或CustTable。它们属于内部联接，因此删除可以使其他记录不在原始查询中。

由于结果集太小，请查找第二个结果集中的记录示例，而不是第一个结果集。然后，获取原始查询，更改为select *并将您在第二个查询中删除的所有内部联接更改为左联接，并查看带有thsoe记录的表数据。您可以考虑仅对记录进行过滤（ s）你有兴趣看到。

查询给出不同的值
