Using SQLXML Bulk Load in the .NET Environment

http://msdn.microsoft.com/en-us/library/ms171878.aspx

1.首先创建一张表

CREATE TABLE Ord (
         OrderID     int identity(1,1)  PRIMARY KEY,
         CustomerID  varchar(5))
GO
CREATE TABLE Product (
         ProductID   int identity(1,1) PRIMARY KEY,
         ProductName varchar(20))
GO
CREATE TABLE OrderDetail (
       OrderID     int FOREIGN KEY REFERENCES Ord(OrderID),
       ProductID   int FOREIGN KEY REFERENCES Product(ProductID),
                   CONSTRAINT OD_key PRIMARY KEY (OrderID, ProductID))
GO

 

 

2.保存一个xml文件schema.xml

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
            xmlns:sql="urn:schemas-microsoft-com:mapping-schema">
<xsd:annotation>
  <xsd:appinfo>
    <sql:relationship name="OrderOD"
          parent="Ord"
          parent-key="OrderID"
          child="OrderDetail"
          child-key="OrderID" />

    <sql:relationship name="ODProduct"
          parent="OrderDetail"
          parent-key="ProductID"
          child="Product"
          child-key="ProductID" 
          inverse="true"/>
  </xsd:appinfo>
</xsd:annotation>

  <xsd:element name="Order" sql:relation="Ord" 
                            sql:key-fields="OrderID" >
   <xsd:complexType>
     <xsd:sequence>
        <xsd:element name="Product" sql:relation="Product" 
                     sql:key-fields="ProductID"
                     sql:relationship="OrderOD ODProduct">
          <xsd:complexType>
             <xsd:attribute name="ProductID" type="xsd:int" />
             <xsd:attribute name="ProductName" type="xsd:string" />
          </xsd:complexType>
        </xsd:element>
     </xsd:sequence>
        <xsd:attribute name="OrderID"   type="xsd:integer" /> 
        <xsd:attribute name="CustomerID"   type="xsd:string" />
    </xsd:complexType>
  </xsd:element>
</xsd:schema>

 

3.再保存另外一个xml文件data.xml

<ROOT>  
  <Order OrderID="11" CustomerID="ALFKI">
    <Product ProductID="11" ProductName="Chai" />
    <Product ProductID="22" ProductName="Chang" />
  </Order>
  <Order OrderID="22" CustomerID="ANATR">
     <Product ProductID="33" ProductName="Aniseed Syrup" />
    <Product ProductID="44" ProductName="Gumbo Mix" />
  </Order>
</ROOT>

 

4.打开VS,创建一个控制台应用程序

5.添加dll引用   In the COM tab, select Microsoft SQLXML Bulkload 4.0 Type Library (xblkld4.dll) and click OK. You will see the Interop.SQLXMLBULKLOADLib assembly created in the project.

坑爹的是,我电脑上根本找不到xblkld4.dll         C:\Program Files\Common Files\System\Ole DB\xblkld4.dll

在我的电脑的 Program Files和Program Files (x86)文件夹下对应的目录都找不到这个dll

 

6.Main函数如下

  static void Main(string[] args)
   {   
         try
         {
            SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class objBL = new SQLXMLBULKLOADLib.SQLXMLBulkLoad4Class();
            objBL.ConnectionString = "Provider=sqloledb;server=server;database=databaseName;integrated security=SSPI";
            objBL.ErrorLogFile = "error.xml";
            objBL.KeepIdentity = false;
            objBL.Execute ("schema.xml","data.xml");
         }
         catch(Exception e)
         {
         Console.WriteLine(e.ToString());
         }
   }
