如何編寫一個數據透視表來顯示每年的列記錄？

Question

我很確定我需要一個樞軸來做到這一點，但不能完全弄清楚。 （SQL福利局）

我的數據是這樣的：

ID CompanyID Year Revenue Expenses 
1  0003   2011 12000  4000 
2  0003   2010 9000  6000 
3  0003   2009 7000  9000 
4  0010   2011 134300  34000 
5  0010   2010 43000  46000 
6  0010   2009 73000  39000 

我可以使用透視來顯示這個表是這樣的：

CompanyID 2011-Revenue 2010-Revenue 2009-Revenue 2011-Expenses 2010-Expenses 2009-Expenses 
0003   12000   9000   7000   4000   6000    9000 
0010   134300   43000   73000   34000   46000   39000 

這裏是我迄今爲止...

SELECT P1.* 
FROM (SELECT [CompanyID] 
      ,CASE P.[Year] WHEN 2011 THEN P.[Revenue] ELSE NULL END AS '2011-Revenue' 
      ,CASE P.[Year] WHEN 2010 THEN P.[Revenue] ELSE NULL END AS '2010-Revenue' 
    FROM tblRecords P WHERE P.[CompanyID] = @companyID GROUP BY CompanyID, [Year], [Revenue]) AS P1 

這是返回：

CompanyID 2011-Revenue 2010-Revenue 
0003   12000   NULL 
0003   NULL   9000 

個

幾個問題，我的結果...

1. 的有兩條記錄爲CompanyID 0003我想它想組進一個記錄

2. 我只能選擇1家公司在時間，我需要選擇多個。我試圖

   FROM tblRecords P 
   WHERE P.[CompanyID] IN (@CompanyIDs) 
   GROUP BY CompanyID, [Year], [Revenue]) AS P1 
   

   凡@CompanyIDs是一個字符串像'0003, 0010' - 它並沒有失敗，但換來的只是一個空表頭和任何數據..

任何幫助，將不勝感激..或讓我知道如果我誤解樞軸？

非常感謝！

更新2：我已經想通了連接表的詳細信息，但我還需要能夠在該CompanyIDs爲越過一個逗號分隔的字符串..任何幫助，將不勝感激。

vvvvvvvv我已經想通了下面這個（會後，一旦所有工作）vvvvvvv

更新：它看起來像什麼魯本提出去上班，但是我剛剛決定我需要多一點的功能對此...我能加入這個與另一個表有頭

CompanyID CompanyName CompanyAddress 2011-Revenue 2010-Revenue 

如果公司名稱和公司地址來自另一個表（tblCompanyDetails）

我使用已經試過：

SELECT * 
FROM 
(
    SELECT CompanyID, tblCompanyDetails.CompanyName, tblCompanyDetails.CompanyAddress, CAST(YEAR AS varchar) + ' - Revenue' Type, 
      Revenue Value FROM tblRecords 
    FROM tblRecords INNER JOIN tblCompanyDetails ON tblRecords.CompanyID = tblCompanyDetails.CompanyID 
    UNION ALL 
    SELECT CompanyID, tblCompanyDetails.CompanyName, tblCompanyDetails.CompanyAddress, CAST(YEAR AS varchar) + ' - Expenses' Type, 
      Expenses Value FROM tblRecords 
    FROM tblRecords INNER JOIN tblCompanyDetails ON tblRecords.CompanyID = tblCompanyDetails.CompanyID 
) src 
    PIVOT 
(
    SUM(Value) for [Type] in 
([2011 - Revenue], [2010 - Revenue], [2009 - Revenue], 
    [2011 - Expenses], [2010 - Expenses], [2009 - Expenses] 
) 
) pvt 
WHERE CompanyID = @CompanyID 

我得到的錯誤：

Msg 1038, Level 15, State 4, Procedure spCompare, Line 10 
An object or column name is missing or empty. For SELECT INTO statements, verify each column has a name. For other statements, look for empty alias names. Aliases defined as "" or [] are not allowed. Add a name or single space as the alias name.

試試這個：

DECLARE @CompanyIDs XML 
DECLARE @Records TABLE 
(
    ID int, 
    CompanyID char(4), 
    Year int, 
    Revenue decimal, 
    Expenses decimal 
) 
DECLARE @CompanyDetails TABLE 
(
    CompanyID char(4), 
    Name varchar(50), 
    Address varchar(50) 
) 

SET @CompanyIDs = ' 
<filter> 
    <CompanyID>0003</CompanyID> 
    <CompanyID>0010</CompanyID> 
</filter>' 

INSERT INTO @Records 
(ID, CompanyID, Year, Revenue, Expenses)VALUES 
(1, '0003', 2011, 12000 , 4000), 
(2, '0003', 2010, 9000 , 6000), 
(3, '0003', 2009, 7000 , 9000), 
(4, '0010', 2011, 134300, 34000), 
(5, '0010', 2010, 43000 , 46000), 
(6, '0010', 2009, 73000 , 39000) 

INSERT INTO @CompanyDetails 
(CompanyID, Name, Address) VALUES 
('0003', 'Company A', 'A Street'), 
('0010', 'Company B', 'B Street') 

SELECT * 
FROM 
(
    SELECT CompanyID, CAST(YEAR AS varchar) + ' - Revenue' Type, 
      Revenue Value FROM @Records 
    UNION ALL 
    SELECT CompanyID, CAST(YEAR AS varchar) + ' - Expenses' Type, 
      Expenses Value FROM @Records 
) src 
PIVOT 
(
    SUM(Value) for [Type] in 
    ([2011 - Revenue], [2010 - Revenue], [2009 - Revenue], 
    [2011 - Expenses], [2010 - Expenses], [2009 - Expenses] 
    ) 
) pvt 
JOIN @CompanyDetails Details 
    ON Details.CompanyId = pvt.CompanyID 
WHERE pvt.CompanyID IN 
(
    SELECT T.C.value('.', 'char(4)') 
    FROM @CompanyIDs.nodes('/filter/CompanyID') T(C) 
) 

您需要將您的公司過濾器作爲XML發送，並使用該子查詢按照樞軸操作的要求中斷數據。對於JOIN操作，只需使用pvt輸出
