我有一个 XML 文件，我需要将其导入到 SQL Server 数据库中。 XML 文件是这样构建的:

<report>
  <deltagere>
    <deltager>
    <number>142555267</number>
    <date>29-12-2006</date>
    <name>
      <name>
        <from>01-05-2000</from>
        <to>01-01-2003</to>
        <text>foo</text>
      </name>
      <name>
        <from>01-01-2003</from>
        <to>29-12-2006</to>
        <text>bzz</text>
      </name>
    </name>
    <information>
      <deltagertype>person</deltagertype>
      <leader>John Smith</leader>
      <status>Active</status>
    </information>
    <role>Responsible</role>
    </deltager>
    <deltager>
      <number>4000134982</number>
      <date>05-12-2007</date>
      <name>
        <name>
          <from>07-07-2007</from>
          <to>05-12-2007</to>
          <text>bar</text>
        </name>
      </name>
      <information>
        <deltagertype>person</deltagertype>
        <leader>Wolfgang Smith</leader>
        <status>Active</status>
      </information>
      <role>Responsible</role>
    </deltager>
    ...
  </deltagere>
</report>

如您所见，名称属性可以包含多个名称。我已经设法将 XML 导入我的数据库，但只有名字属性。 到目前为止我写的代码是:

DECLARE @XmlFile XML

SELECT @XmlFile = BulkColumn
FROM  OPENROWSET(BULK 'C:\input.xml', SINGLE_BLOB) x;

INSERT INTO dbo.deltagere(number, dato, nameFrom, nameTo, nameText, deltagertype, leader, deltagerStatus, deltagerRole)
SELECT
  number = deltagere.value('(number)[1]', 'bigint'),
  dato = deltagere.value('(date)[1]', 'varchar(10)'),
  nameFrom = deltagere.value('(name/name/from)[1]', 'varchar(10)'),
  nameTo = deltagere.value('(name/name/to)[1]', 'varchar(10)'),
  nameText = deltagere.value('(name/name/text)[1]', 'varchar(30)'),
  deltagertype = deltagere.value('(information/deltagertype)[1]', 'varchar(20)'),
  leader = deltagere.value('(information/leader)[1]', 'varchar(50)'),
  deltagerStatus = deltagere.value('(information/status)[1]', 'varchar(50)'),
  deltagerRole = deltagere.value('(role)[1]', 'varchar(50)')
FROM
  @XmlFile.nodes('/report/deltagere/deltager') AS XTbl(deltagere);

这给了我这个输出:

| number     | dato       | nameFrom   | nameTo     | nameText | deltagertype | ...
| 142555267  | 29-12-2006 | 01-05-2000 | 01-01-2003 | foo      | person       | ...
| 4000134982 | 05-12-2007 | 07-07-2007 | 05-12-2007 | bar      | person       | ...

我想为每个名字/名字排一行。所以像这样:

-------------------------------------------------------
| number     | dato       | nameFrom   | nameTo     | nameText | deltagertype | ...
| 142555267  | 29-12-2006 | 01-05-2000 | 01-01-2003 | foo      | person       | ...
| 142555267  | 29-12-2006 | 01-01-2003 | 29-12-2006 | bzz      | person       | ...
| 4000134982 | 05-12-2007 | 07-07-2007 | 05-12-2007 | bar      | person       | ...

等等。

我真的不知道该怎么做。因此，我希望你们中的任何人对如何修改我的代码以允许这个问题有任何想法，或者可能对这个问题采取不同的方法。

最佳答案

试试这个 - 你需要再做一次 .nodes()调用枚举所有<name>子节点:

SELECT
    number = deltagere.value('(number)[1]', 'bigint'),
    dato = deltagere.value('(date)[1]', 'varchar(10)'),
    -- NEW NEW NEW - read from `XC` pseudo columns to get 1-n names
    nameFrom = XC.value('(from)[1]', 'varchar(10)'),
    nameTo = XC.value('(to)[1]', 'varchar(10)'),
    nameText = XC.value('(text)[1]', 'varchar(30)'),
    deltagertype = deltagere.value('(information/deltagertype)[1]', 'varchar(20)'),
    leader = deltagere.value('(information/leader)[1]', 'varchar(50)'),
    deltagerStatus = deltagere.value('(information/status)[1]', 'varchar(50)'),
    deltagerRole = deltagere.value('(role)[1]', 'varchar(50)')
FROM
    @XmlFile.nodes('/report/deltagere/deltager') AS XTbl(deltagere)
CROSS APPLY
    deltagere.nodes('name/name') AS XT2(XC)
