Question

我的任务是从我们的数据库中获取一些与Instant Atlas一起使用的数据。我创建了一个查询，它将返回我想在地图上显示的数据。我遇到的问题是我似乎无法正确格式化XML。我已经能够掌握模式（Instant Atlas），但我不知道如何在SQL执行期间应用格式化。

我的查询如下;

-- start of monthly pivot+ union

--Start of inner Pivot
DECLARE @year INT = 2015

SELECT 
[LAName] AS '@LA' , [1] AS 'Jan', [2] AS 'Feb', [3] AS 'Mar', [4] AS 'Apr', 
[5] AS 'May', [6] AS 'Jun', [7] AS 'Jul', [8] AS 'Aug', [9] AS 'Sep',
[10] AS 'Oct', [11] AS 'Nov', [12] AS 'Dec', 
[1] + [2] + [3] + [4] + [5] + [6] + [7] + [8] + [9] + [10] + [11] + [12] AS 'Total' , 1 as [sort]

FROM
(SELECT
L.LAName AS [LAName],
SUBSTRING(C.AgencyCode, 1, 3) AS [AgencyCode],
DATEPART(MONTH, ST.TransactionDate) as 'Date',
DATEPART(YEAR, ST.TransactionDate) as 'Year',
ST.TransactionId AS 'SyringeTransactions'
FROM SyringeTransaction AS ST
JOIN Client as C
ON C.ClientId = ST.ClientId
JOIN LocalAuthority as L
ON SUBSTRING(C.AgencyCode, 1, 3) = L.LAShortCode
WHERE SUBSTRING(C.AgencyCode, 1, 3) != 'XXX' AND C.Consent = 1 AND DATEPART(YEAR, ST.TransactionDate) = @year ) AS SourceTable
PIVOT
(count(SyringeTransactions) FOR SourceTable.[Date] IN
([1], [2], [3], [4], [5], [6], [7], [8], [9] ,[10], [11], [12])

) AS Transactions_2015_Area
UNION
--end of innerPivot
--Start of outerPivot

SELECT 
[AgencyCode] AS '@LA' , [1] AS 'Jan', [2] AS 'Feb', [3] AS 'Mar', [4] AS 'Apr', 
[5] AS 'May', [6] AS 'Jun', [7] AS 'Jul', [8] AS 'Aug', [9] AS 'Sep',
[10] AS 'Oct', [11] AS 'Nov', [12] AS 'Dec', 
[1] + [2] + [3] + [4] + [5] + [6] + [7] + [8] + [9] + [10] + [11] + [12] AS 'Total', 2 AS [sort]

FROM
(SELECT
C.AgencyCode AS [AgencyCode],
DATEPART(MONTH, ST.TransactionDate) as 'Date',
DATEPART(YEAR, ST.TransactionDate) as 'Year',
ST.TransactionId AS 'SyringeTransactions'
FROM SyringeTransaction AS ST
JOIN Client as C
ON C.ClientId = ST.ClientId
WHERE SUBSTRING(C.AgencyCode, 1, 3) != 'XXX' AND C.Consent = 1 AND DATEPART(YEAR, ST.TransactionDate) = @year ) AS SourceTable
PIVOT
(count(SyringeTransactions) FOR SourceTable.[Date] IN
([1], [2], [3], [4], [5], [6], [7], [8], [9] ,[10], [11], [12])

) AS Transactions_2015_Agency

ORDER BY [sort], [@LA]
--end of outerPivot

-- end of pivot with union
FOR XML PATH('Geography'), ROOT('SyringeTransactions'), TYPE

我需要匹配的架构如下;

如同要求的那样，这就是我完成它时“应该”看的XML。

由于数据保护原因，我不得不删除值

Answer 1

关于你的实际表格很难帮助你，但这会给你一个想法，你如何建立你需要的结构。

我将模拟表与虚拟数据一起使用（这是您应该提供的，以便创建 MCVE（最小，可验证，完整的示例）。

DECLARE @indicator TABLE(RowID INT IDENTITY, Name VARCHAR(100),ID VARCHAR(100),[Date] VARCHAR(100),[Precision] INT,[Type] VARCHAR(100));
INSERT INTO @indicator VALUES('All individuals','i0','2014-15 Q1',0,'numeric')
                            ,('All individuals','i0','2014-15 Q1',0,'numeric');

DECLARE @values TABLE(indicatorID INT,forText VARCHAR(100),Value INT);
INSERT INTO @values VALUES(1,'yyyyyyy',100)
                         ,(1,'yyyyyyy',200)  
                         ,(1,'yyyyyyy',300)  
                         ,(1,'yyyyyyy',400)  
                         ,(1,'yyyyyyy',500)  
                         ,(1,'yyyyyyy',600)  
                         ,(1,'yyyyyyy',700)  
                         ,(1,'yyyyyyy',800)  
                         ,(1,'yyyyyyy',900)  

                         ,(2,'yyyyyyy',110)
                         ,(2,'yyyyyyy',210)  
                         ,(2,'yyyyyyy',310)  
                         ,(2,'yyyyyyy',410)  
                         ,(2,'yyyyyyy',510)  
                         ,(2,'yyyyyyy',610)  
                         ,(2,'yyyyyyy',710)  
                         ,(2,'yyyyyyy',810)  
                         ,(2,'yyyyyyy',910);

- 查询

--Create without namespaces (otherwise each sub-select would get the namespace declaration
DECLARE @InnerXML XML=
(
    SELECT i.Name AS [@name]
            ,i.ID AS [@id]
            ,i.Date AS [@date]
            ,i.Precision AS [@precision]
            ,i.Type AS [@type]
            ,(
            SELECT v.forText AS [@for]
                  ,v.Value AS [*]
            FROM @values AS v
            WHERE v.indicatorID=i.RowID
            FOR XML PATH('Value'),TYPE
            )
    FROM @indicator AS i
    FOR XML PATH('Indicator'),TYPE
);

WITH XMLNAMESPACES(DEFAULT 'http://data.instantatlas.com/atlas')
SELECT 'xxxxxx' AS [@name]
      ,'t0' AS [@id]
      ,@innerXML AS [*]
FOR XML PATH('Theme')

结果：

<Theme xmlns="http://data.instantatlas.com/atlas" name="xxxxxx" id="t0">
  <Indicator name="All individuals" id="i0" date="2014-15 Q1" precision="0" type="numeric" xmlns="">

    <Value for="yyyyyyy">200</Value>
    <Value for="yyyyyyy">300</Value>
    <Value for="yyyyyyy">400</Value>
    <Value for="yyyyyyy">500</Value>
    <Value for="yyyyyyy">600</Value>
    <Value for="yyyyyyy">700</Value>
    <Value for="yyyyyyy">800</Value>
    <Value for="yyyyyyy">900</Value>
  </Indicator>
  <Indicator name="All individuals" id="i0" date="2014-15 Q1" precision="0" type="numeric" xmlns="">

    <Value for="yyyyyyy">710</Value>
    <Value for="yyyyyyy">810</Value>
    <Value for="yyyyyyy">910</Value>
  </Indicator>
</Theme>
