任何有关以下内容的帮助将不胜感激。

下面是我的表结构：

CREATE TABLE [dbo].[XML_EXAMPLE]
(
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Account Code] [varchar](15) NULL,
    [Description] [varchar](50) NULL,
    [Analysis 1 Code] [varchar](15) NULL,
    [Analysis 2 Code] [varchar](15) NULL,
    [Analysis 3 Code] [varchar](15) NULL,
    [Analysis 4 Code] [varchar](15) NULL,
    [Analysis 5 Code] [varchar](15) NULL,
    [Analysis 6 Code] [varchar](15) NULL,
    [Analysis 7 Code] [varchar](15) NULL
) ON [PRIMARY]
GO

在该表中，我将插入 4 行。两行的分析 1 代码为 1000，另外两行的分析 1 代码为 2000。

INSERT INTO [dbo].[XML_EXAMPLE] ([Analysis 1 Code])
VALUES ('1000'), ('1000'), ('2000'), ('2000')

我试图从 SQL 中得到的是一种如下所示的 XML 格式 - 请注意，如果您查看 CompCode，每个 Analysis 1 Code 都有它自己的“文档”元素。每个 Document 元素都有一个 Header 和 Item（表中的行）。

<DocumentBatch>
  <Document>
    <Header>
      <DocType>HR</DocType>
      <CompCode>1000</CompCode>
      <DocDate>20211018</DocDate>
      <PostDate>20211018</PostDate>
      <RefDocNo>Civica Cx Rents</RefDocNo>
      <Text>Civica Cx Rents</Text>
    </Header>
    <Item>

    </Item>
  </Document>
<Document>

            <RefKey2>RefKey2</RefKey2>
            <RefKey3>RefKey3</RefKey3>
        </Item>
        <Item>
            <ItemNo>2</ItemNo>

            <RefKey3>RefKey3</RefKey3>
        </Item>
    </Document>
</DocumentBatch>

我编写的代码只处理其中一个分析 1 代码。如果你要运行这段代码——你会看到它只会给我想要的一半。

SELECT
    (SELECT 
         (SELECT DISTINCT 
              'HR' DocType, 
              x.[Analysis 1 Code] CompCode, 
              CONVERT(varchar(8), GETDATE(), 112) DocDate, 
              CONVERT(varchar(8), GETDATE(), 112) PostDate, 
              'Civica Cx Rents' RefDocNo, 
              'Civica Cx Rents' Text
          FROM 
              XML_EXAMPLE x
          WHERE 
              x.[Analysis 1 Code] = '1000'
          FOR XML path('Header'), TYPE),
         (SELECT  
              ROW_NUMBER() OVER (ORDER BY id) 'ItemNo',
              'GIAccNo' 'GIAccNo',
              'TaxCode' 'TaxCode',
              'Amount' 'Amount',
              'Currency' 'Currency',
              'Text' 'Text',
              'CostCenter' 'CostCenter',
              'RefKey1' 'RefKey1',
              'RefKey2' 'RefKey2',
              'RefKey3' 'RefKey3'
          FROM 
              XML_EXAMPLE x
          WHERE 
              x.[Analysis 1 Code] = '1000'
          FOR XML PATH('Item'), TYPE)
      FOR XML PATH('Document'), TYPE, ROOT ('DocumentBatch')) row

我的结果 - 请注意，我只有 1 个带有标题和 1000 项的 Document 元素。

<DocumentBatch>
  <Document>
    <Header>
      <DocType>HR</DocType>
      <CompCode>1000</CompCode>
      <DocDate>20211018</DocDate>
      <PostDate>20211018</PostDate>
      <RefDocNo>Civica Cx Rents</RefDocNo>
      <Text>Civica Cx Rents</Text>
    </Header>
    <Item>
      <ItemNo>1</ItemNo>
      <GIAccNo>GIAccNo</GIAccNo>
      <TaxCode>TaxCode</TaxCode>
      <Amount>Amount</Amount>
      <Currency>Currency</Currency>
      <Text>Text</Text>
      <CostCenter>CostCenter</CostCenter>
      <RefKey1>RefKey1</RefKey1>
      <RefKey2>RefKey2</RefKey2>
      <RefKey3>RefKey3</RefKey3>
    </Item>
    <Item>
      <ItemNo>2</ItemNo>
      <GIAccNo>GIAccNo</GIAccNo>
      <TaxCode>TaxCode</TaxCode>
      <Amount>Amount</Amount>
      <Currency>Currency</Currency>
      <Text>Text</Text>
      <CostCenter>CostCenter</CostCenter>
      <RefKey1>RefKey1</RefKey1>
      <RefKey2>RefKey2</RefKey2>
      <RefKey3>RefKey3</RefKey3>
    </Item>
  </Document>
</DocumentBatch>

我一辈子都做不到的是——

  1. 我如何<?xml version="1.0" encoding="iso8859-1"?>附加到我生成的 XML 格式的顶部 - 因为我将通过 SSIS 包进行设置。

  2. 我在我的代码中放置在哪里，以便它最终导出 1000 和 2000，因为我正在努力将它放置在哪里。我是否错误地构建了我的代码以实现我想要实现的目标？

非常感谢

请尝试以下解决方案。

它使用 SQL Server 的 XQuery 及其 FLWOR 表达式。

XML 组合分两步完成：

  1. 原始 XML 通过FOR XML PATH(...).
  2. 通过 XQuery FLWOR 表达式最终微调 XML。

SQL

-- DDL and sample data population, start
DECLARE @tbl TABLE
(
    ID int IDENTITY PRIMARY KEY,
    Account_Code varchar(15) NULL,
    [Description] varchar(50) NULL,
    Analysis_1_Code varchar(15) NULL
);
INSERT INTO @tbl (Analysis_1_Code) VALUES 
('1000'), ('1000'), ('2000'), ('2000');
-- DDL and sample data population, end

SELECT (
    SELECT * 
    , seq = ROW_NUMBER() OVER (PARTITION BY Analysis_1_Code ORDER BY ID)
    FROM @tbl
    FOR XML PATH('r'), TYPE, ROOT('root'))
.query('<DocumentBatch>
{
for $x in distinct-values(/root/r/Analysis_1_Code)
return (<Document>
        <Header>
            <DocType>HR</DocType>
            <CompCode>{$x}</CompCode>
            <DocDate>20211018</DocDate>
            <PostDate>20211018</PostDate>
            <RefDocNo>Civica Cx Rents</RefDocNo>
            <Text>Civica Cx Rents</Text>
        </Header>
    </Document>,
    for $y in /root/r[Analysis_1_Code=$x]
    return <Item>
            <ItemNo>{data($y/seq)}</ItemNo>
            <GIAccNo>GIAccNo</GIAccNo>
            <TaxCode>TaxCode</TaxCode>
            <Amount>Amount</Amount>
            <Currency>Currency</Currency>
            <Text>Text</Text>
            <CostCenter>CostCenter</CostCenter>
            <RefKey1>RefKey1</RefKey1>
            <RefKey2>RefKey2</RefKey2>
            <RefKey3>RefKey3</RefKey3>
        </Item>)
}
</DocumentBatch>');

输出
