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',

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

答案 0 :(得分：0)
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">
