【中文标题】SQL XML - 从 SQL Server 为发票创建一个 XML 文件，包括一个 XML 文件中的发票位置【英文标题】：SQL XML - Create a XML file from SQL Server for an invoice including invoice positions in one XML file 【发布时间】：2020-10-27 13:13:02 【问题描述】：我以这种方式创建我的xml文件（我没有显示所有输出字段，因为有很多字段）：
DECLARE @ID_Rechnung int = 8;
WITH XMLNAMESPACES (
'urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2' as ext,
'urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2' as cbc,
'urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2' as cac,
'http://uri.etsi.org/01903/v1.3.2#' as xades,
'http://www.w3.org/2001/XMLSchema-instance' as xsi,
'http://www.w3.org/2000/09/xmldsig#' as ds
)
SELECT
@XMLData = xmldat.xmldataCol
FROM
(
SELECT
(
SELECT
-- HIER XML Daten generieren
'' AS 'ext:UBLExtensions',
'' AS 'ext:UBLExtensions/ext:UBLExtension',
'' AS 'ext:UBLExtensions/ext:UBLExtension/ext:ExtensionContent',
'2.1' AS 'cbc:UBLVersionID',
'TR1.2' AS 'cbc:CustomizationID',
'' AS 'cbc:ProfileID',
Rechnungen.Nummer AS 'cbc:ID',
'false' AS 'cbc:CopyIndicator',
'' AS 'cbc:UUID',
CAST(Rechnungen.Datum AS Date) AS 'cbc:IssueDate'
FROM
rechnungen
WHERE
rechnungen.id = @ID_Rechnung
FOR XML PATH(''), ROOT('Invoice')
) AS xmldataCol
这很好用 - 我得到以下 XML：
<Invoice xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xades="http://uri.etsi.org/01903/v1.3.2#" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2">
<ext:UBLExtensions>
<ext:UBLExtension>
<ext:ExtensionContent />
</ext:UBLExtension>
</ext:UBLExtensions>
<cbc:UBLVersionID>2.1</cbc:UBLVersionID>
<cbc:CustomizationID>TR1.2</cbc:CustomizationID>
<cbc:ProfileID />
<cbc:ID>R200001</cbc:ID>
<cbc:CopyIndicator>false</cbc:CopyIndicator>
<cbc:UUID />
<cbc:IssueDate>2020-06-29</cbc:IssueDate>
</Invoice>
但现在我需要同一文件中的发票位置。
此 SQL 应包含在第一个 SQL 中，日期应为 xml 文件中的发票行：
SELECT
Rechnungpos.ID AS 'cac:InvoiceLine/cbc:ID',
Rechnungpos.Anzahl AS 'cac:InvoiceLine/cbc:InvoicedQuantity'
FROM
RechnungPos
WHERE
RechnungPos.id_Rechnung = @ID_Rechnung
输出应该是这样的：
<Invoice xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xades="http://uri.etsi.org/01903/v1.3.2#" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2">
<ext:UBLExtensions>
<ext:UBLExtension>
<ext:ExtensionContent />
</ext:UBLExtension>
</ext:UBLExtensions>
<cbc:UBLVersionID>2.1</cbc:UBLVersionID>
<cbc:CustomizationID>TR1.2</cbc:CustomizationID>
<cbc:ProfileID />
<cbc:ID>R200001</cbc:ID>
<cbc:CopyIndicator>false</cbc:CopyIndicator>
<cbc:UUID />
<cbc:IssueDate>2020-06-29</cbc:IssueDate>
<cac:InvoiceLine>
<cbc:ID>1<(cbc:>
<cbc:InvoicedQuantity>3</cbc:InvoicedQuantity>
</cac:InvoiceLine>
<cac:InvoiceLine>
<cbc:ID>5<(cbc:>
<cbc:InvoicedQuantity>1</cbc:InvoicedQuantity>
</cac:InvoiceLine>
<cac:InvoiceLine>
<cbc:ID>9<(cbc:>
<cbc:InvoicedQuantity>2</cbc:InvoicedQuantity>
</cac:InvoiceLine>
</Invoice>
这是生成测试数据的代码：
CREATE TABLE [dbo].[Rechnungen](
[id] [int] NOT NULL,
[Nummer] [nvarchar](20) NOT NULL,
[Datum] [datetime] NOT NULL
)
INSERT INTO Rechnungen (id, Nummer, Datum) VALUES (8, 'R200001', '29.06.2020')
CREATE TABLE [dbo].Rechnungpos(
[id] [int] NOT NULL,
[id_Rechnung] [int] NOT NULL,
[Anzahl] [float] NOT NULL
)
INSERT INTO RechnungPos (id, id_Rechnung, Anzahl) VALUES (1, 8, 3)
INSERT INTO RechnungPos (id, id_Rechnung, Anzahl) VALUES (5, 8, 1)
INSERT INTO RechnungPos (id, id_Rechnung, Anzahl) VALUES (9, 8, 2)
它必须在不同版本上运行 - 我的版本是 SQL Server 2019
我该怎么做？
谢谢你的帮助，托马斯。
【问题讨论】：
在提出问题时，您需要提供一个可重现的最小示例。请参考以下链接：***.com/help/minimal-reproducible-example 请提供以下内容： (1) DDL 和样本数据填充，即 CREATE table(s) 加上 INSERT T-SQL 语句。 (2) 你需要做什么，即逻辑和你的代码尝试实现它。 (3) 期望的输出，基于上面#1 中的样本数据。 (4) 你的 SQL Server 版本 (SELECT @@version;) Thomas，我之前评论中的 (1) 和 (4) 仍然丢失。请提供。 感谢您的回答 - 我现在制作 1 和 4 - 感谢您的帮助 【参考方案1】：这里是怎么做的。
唯一的复杂性是如何处理输出 XML 中的子表和特别是命名空间。这就是使用 XQuery 及其 FLWOR 表达式的原因。

【讨论】：
感谢您的解决方案 - 它适用于测试数据。但是，如果我在我需要的 xm 中使用来自 Rechnungen 的所有字段进行尝试，那么我会收到一条错误消息：无法调用 nvarchar (max) 的方法。 （我从德语翻译成英语）并且标记了 .query 命令 我找到了解决方案 - 我将所有选定的数据放在 XML 类型的变量 @XMLData 之后 id 为：SELECT @XMLData.query
@Thomas，很高兴听到您找到了完整的解决方案，尽管它似乎过于复杂。请在 LinkedIn 上与我联系。【参考方案2】：
