SQLXMLBULKLOAD赢得'；我不能使用我的XSD

这是由于这种关系造成的，这种关系似乎不受支持：

我无法更改XML的格式，因为它来自第三方。其XML中有两个部分包含RateRegister，例如：

<wse:ImportRateRegisters>
  <wse:RateRegister Tier="0" Cumulative="3213.500" Advance="60.900" />
  <wse:RateRegister Tier="1" Cumulative="193.950" Advance="59.700" />
</wse:ImportRateRegisters>
<wse:ImportTierRegisters>
  <wse:RateRegister Tier="0" Cumulative="3251.600" />
  <wse:RateRegister Tier="1" Cumulative="351.000" />
</wse:ImportTierRegisters>

如果我尝试添加这两个关系，我会得到一个重复的属性错误

我在这里浪费时间了吗，SQLXMLBULKLOAD实用程序能处理这种层次结构吗？

我终于成功地实现了这一点，因此我将发布我的答案，希望它能帮助其他人解决类似的问题。我不相信这是最好的解决方案，因为它最终会创建我并不真正想要的“链接表”，但它确实有效

在数据库中，我创建表来保存结构的这一部分：

CREATE TABLE ImportRateRegisters (
    RRegisterId INT IDENTITY(1,1) PRIMARY KEY,
    DeviceId INT FOREIGN KEY REFERENCES Device(DeviceId));

CREATE TABLE ImportTierRegisters (
    TRegisterId INT IDENTITY(1,1) PRIMARY KEY,
    DeviceId INT FOREIGN KEY REFERENCES Device(DeviceId));

CREATE TABLE RRateRegister (
    Tier INT,
    Cumulative NUMERIC(19,2),
    Advance NUMERIC(19,2),
    RRegisterId INT FOREIGN KEY REFERENCES ImportRateRegisters(RRegisterId));

CREATE TABLE TRateRegister (
    Tier INT,
    Cumulative NUMERIC(19,2),
    Advance NUMERIC(19,2),
    TRegisterId INT FOREIGN KEY REFERENCES ImportTierRegisters(TRegisterId));

首先，我需要为RateRegister创建一个元素，将它连接到RRateRegister或TRAterRegister表，我在XSD中进一步覆盖它，但我需要在这里有一些内容作为占位符，否则批量加载时会出错

  <xs:element name="RateRegister" msdata:Prefix="wse" sql:relation="RRateRegister" sql:relationship="RRateRegisterToImportRateRegisters">
    <xs:complexType>
      <xs:attribute name="Tier" form="unqualified" type="xs:string" sql:field="Tier" />
      <xs:attribute name="Cumulative" form="unqualified" type="xs:string" sql:field="Cumulative" />
      <xs:attribute name="Advance" form="unqualified" type="xs:string" sql:field="Advance" />
    </xs:complexType>
  </xs:element>

当我谈到核心XSD中导致问题的部分时，我会返回到通用RateRegister，但会覆盖关系/关系：

      <xs:element name="ImportRateRegisters" msdata:Prefix="wse" minOccurs="0" maxOccurs="unbounded" sql:relation="ImportRateRegisters" sql:relationship="ImportRateRegistersToDevice">
        <xs:complexType>
          <xs:sequence>
            <xs:element ref="RateRegister" minOccurs="0" maxOccurs="unbounded" sql:relation="RRateRegister" sql:relationship="RRateRegisterToImportRateRegisters"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
      <xs:element name="ImportTierRegisters" msdata:Prefix="wse" minOccurs="0" maxOccurs="unbounded" sql:relation="ImportTierRegisters" sql:relationship="ImportTierRegistersToDevice">
        <xs:complexType>
          <xs:sequence>
            <xs:element ref="RateRegister" minOccurs="0" maxOccurs="unbounded" sql:relation="TRateRegister" sql:relationship="TRateRegisterToImportTierRegisters" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>

…就这样。当我加载数据时，它会被推送到正确的RateRegister表中，并且所有数据似乎都正确地链接在一起

CREATE TABLE ImportRateRegisters (
    RRegisterId INT IDENTITY(1,1) PRIMARY KEY,
    DeviceId INT FOREIGN KEY REFERENCES Device(DeviceId));

CREATE TABLE ImportTierRegisters (
    TRegisterId INT IDENTITY(1,1) PRIMARY KEY,
    DeviceId INT FOREIGN KEY REFERENCES Device(DeviceId));

CREATE TABLE RRateRegister (
    Tier INT,
    Cumulative NUMERIC(19,2),
    Advance NUMERIC(19,2),
    RRegisterId INT FOREIGN KEY REFERENCES ImportRateRegisters(RRegisterId));

CREATE TABLE TRateRegister (
    Tier INT,
    Cumulative NUMERIC(19,2),
    Advance NUMERIC(19,2),
    TRegisterId INT FOREIGN KEY REFERENCES ImportTierRegisters(TRegisterId));

  <xs:element name="RateRegister" msdata:Prefix="wse" sql:relation="RRateRegister" sql:relationship="RRateRegisterToImportRateRegisters">
    <xs:complexType>
      <xs:attribute name="Tier" form="unqualified" type="xs:string" sql:field="Tier" />
      <xs:attribute name="Cumulative" form="unqualified" type="xs:string" sql:field="Cumulative" />
      <xs:attribute name="Advance" form="unqualified" type="xs:string" sql:field="Advance" />
    </xs:complexType>
  </xs:element>

      <xs:element name="ImportRateRegisters" msdata:Prefix="wse" minOccurs="0" maxOccurs="unbounded" sql:relation="ImportRateRegisters" sql:relationship="ImportRateRegistersToDevice">
        <xs:complexType>
          <xs:sequence>
            <xs:element ref="RateRegister" minOccurs="0" maxOccurs="unbounded" sql:relation="RRateRegister" sql:relationship="RRateRegisterToImportRateRegisters"/>
          </xs:sequence>
        </xs:complexType>
      </xs:element>
      <xs:element name="ImportTierRegisters" msdata:Prefix="wse" minOccurs="0" maxOccurs="unbounded" sql:relation="ImportTierRegisters" sql:relationship="ImportTierRegistersToDevice">
        <xs:complexType>
          <xs:sequence>
            <xs:element ref="RateRegister" minOccurs="0" maxOccurs="unbounded" sql:relation="TRateRegister" sql:relationship="TRateRegisterToImportTierRegisters" />
          </xs:sequence>
        </xs:complexType>
      </xs:element>
