SQL Server FOR XML 生成相同名称节点时出现显式错误答案

【问题标题】：SQL Server FOR XML explicit error in generating same name nodesSQL Server FOR XML 生成相同名称节点时出现显式错误
【发布时间】：2015-12-04 14:56:58
【问题描述】：

我正在尝试使用 XML Explicit 生成以下 XML 结构

<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">
<Worksheet ss:Name="1">
    <Table>
        <Row>
            <Cell>
                <Data ss:Type="String">231548</Data>
            </Cell>
            <Cell>
                <Data ss:Type="String">2014-11-03T20:03:30</Data>
            </Cell>
        </Row>
    </Table>
</Worksheet>

我可以生成

 <Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">
  <Worksheet ss:Name="1">
    <Table>
      <Row>
        <Cell>
          <Data ss:Type="String">231548</Data>
        </Cell>
      </Row>
    </Table>
  </Worksheet>
</Workbook>

我无法生成上述结构。我用来生成结构的代码如下。

SELECT 
    Tag, 
    Parent,
    [Workbook!1!xmlns],
    [Workbook!1!xmlns:ss],
    [Worksheet!2!ss:Name],
    [Table!3!],
    [Row!4!],
    [Cell!5!],
    [Data!6!ss:Type],
    [Data!6!]

SELECT top 5
    1 AS Tag,
    0 AS Parent,
    0 as SORT,

    'urn:schemas-microsoft-com:office:spreadsheet' AS [Workbook!1!xmlns:ss],
    NULL AS [Worksheet!2!ss:Name],
    NULL AS [Table!3!],
    NULL AS [Row!4!],
    NULL AS [Cell!5!],
    NULL AS [Data!6!ss:Type],
    NULL AS [Data!6!]

谁能帮帮我。任何帮助将不胜感激。我正在使用此代码生成可以在 excel 中打开的 xml。

【问题讨论】：

看看FOR XML PATH，它通常比显式模式容易得多，而且几乎可以做任何事情
@marc_s 感谢您的建议。我也在尝试。你能帮我解决上面的问题吗？
@marc_s 你能帮我使用 XML 路径生成相同的 XML。
如果您可以提供SQL Fiddle 与表结构和一些示例数据 - 是的，可能
@marc_s 感谢您抽出时间为我提供帮助。我已经在 [link]sqlfiddle.com/#!9/126210 创建了表格和示例条目

【解决方案1】：

假设您确实想要使用 XML Explicit 来生成此输出，您可以为 Cell 和 Data 添加另外两个标签以及两个后续的 Union Queries。

编辑：我在标签 2 的 Worksheet!2!ss:Name 列中添加了一个 1，以确保输出符合您的要求。

    Parent,
