SQL Server 2005 - 嵌套 XML

Question

我以这个问题/答案为起点。 SQL Server : nesting elements with FOR XML PATH

我正在尝试获取此输出。

我的#TempTable 将是我从数据仓库构建的自定义表，因此我首先使用一些示例数据。有没有比我正在做的更简单的方法来获取 XML？

CREATE TABLE #TempTable 
(
     [FieldName] char(15),
     [FieldValue1] char(15),
     [FieldValue2] char(15),
     [CategoryName] char(15), 
     [Customer] char(15)
)

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test1Cust1', '100', '150', 'ProductLine1', 'Customer1')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test1Cust1', '100', '15110', 'ProductLine1', 'Customer1')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test1Cust2', '100', '150', 'ProductLine1', 'Customer2')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test1Cust2', '110', '15110', 'ProductLine1', 'Customer2')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Tes2Cust1', '200', '250', 'ProductLine2', 'Customer1')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Tes2Cust2', '200', '250', 'ProductLine2', 'Customer2')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test3Cust1', '300', '350', 'ProductLine3', 'Customer1')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test3Cust2', '300', '350', 'ProductLine3', 'Customer2')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test4Cust1', '400', '450', 'ProductLine4', 'Customer1')

INSERT INTO #TempTable([FieldName], [FieldValue1], [FieldValue2], [CategoryName], [Customer]) 
VALUES ('Test4Cust2', '400', '450', 'ProductLine4', 'Customer2')

SELECT 
    (SELECT 
         RTRIM(T1.Customer) AS "@ExID",
         (SELECT 
              RTRIM(T2.CategoryName) AS "@ID",
              (SELECT 
                   RTRIM(T3.FieldName) AS FieldName,
                   RTRIM(T3.FieldValue1) AS FieldValue1,
                   RTRIM(T3.FieldValue2) AS FieldValue2
               FROM 
                   #TempTable T3
               WHERE 
                   T2.categoryname = T3.CategoryName 
                   AND T2.Customer = T3.Customer
               FOR XML path('Field'), root('SalesByFields'), type)
          FROM 
              #TempTable AS T2
          WHERE 
              T1.Customer = T2.Customer
          GROUP BY 
              T2.CategoryName, T2.Customer
          FOR XML path('CategoryName'), type)
    FROM 
        #TempTable AS T1
    GROUP BY 
        T1.Customer
    FOR XML path('Account'), TYPE)
FOR XML path('Accounts')

DROP TABLE #TempTable

Answer 1

这就是我想出的以我需要的方式构建 XML 的方法。对于任何感兴趣的人，这是用于在 Pepperi 移动软件上加载仪表板报告。

SELECT (
    SELECT RTRIM(T1.Customer) AS "@ExID",
            (
                SELECT RTRIM(T2.CategoryName) AS "@ID"
                        , 'Prior vs current period sales for ' + RTRIM(T2.CategoryName) AS "ChartName"
                        , 'Target' AS "ValuesDescription/Value1"
                        , 'Actual' AS "ValuesDescription/Value2"
                        ,
                        (
                            SELECT RTRIM(T3.FieldName) AS FieldName
                                    , SUM(T3.FieldValue1) AS FieldValue1
                                    , SUM(T3.FieldValue2) AS FieldValue2
                            FROM #TempTable T3
                            WHERE T2.categoryname = T3.CategoryName AND
                                    T2.Customer = T3.Customer
                            GROUP BY T3.FieldName
                            FOR XML PATH('Field')
                                ,ROOT('SalesByFields')
                                ,TYPE
                        )
                        ,
                        (
                            SELECT T4.FieldName AS FieldName
                                    , SUM(T4.FieldValue) AS FieldValue
                            FROM #CurVsPrior T4
                            WHERE T2.Customer = T4.AddressID AND
                                    T2.CategoryName = T4.Brand
                            GROUP BY  T4.FieldName
                            FOR XML PATH('Field')
                                ,ROOT('TotalSales')
                                ,TYPE
                        )
                FROM #TempTable AS T2
                WHERE T1.Customer = T2.Customer
                GROUP BY T2.CategoryName, T2.Customer
                FOR XML PATH('CategoryName')
                    ,TYPE
            ) AS "AccountData/TwoColumnsChart"
    FROM #TempTable AS T1
    GROUP BY T1.Customer
    FOR XML PATH('Account')
        ,TYPE
    )

FOR XML PATH('Accounts')
