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());

         }

   }
