將數據從訪問複製到現有的SQL Server表

Question

該代碼將數據從訪問複製到SQL服務器表。 但這段代碼有一些問題。

1. 此代碼無法將數據從訪問權限複製到SQL服務器表所在的數據。

我的SQL服務器表有一些數據，我想從訪問中添加數據到SQL服務器表中的現有數據。

如何將數據添加到現有表中？

無法從Access 2007年或2010年

讀取數據如何從訪問讀取數據2007/2010

OpenFileDialog openfiledialog1 = new OpenFileDialog(); 
     openfiledialog1.Title = "select access file"; 

      openfiledialog1.Filter = "Access 2003 (*.mdb)|*.mdb|Access 2007|*.accdb"; 
      if (openfiledialog1.ShowDialog() == DialogResult.OK) 
      { 

       string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + openfiledialog1.FileName; 
       const string connectionStringDest = @"server=ahmad-pc\anfd;database = phonebook;Integrated Security = true"; 
       using (var sourceConnection = new OleDbConnection(connectionString)) 
       { 
        sourceConnection.Open(); 

        var commandSourceData = new OleDbCommand("SELECT * from numberperson", sourceConnection); 
        var reader = commandSourceData.ExecuteReader(); 

        using (var destinationConnection = new SqlConnection(connectionStringDest)) 
        { 
         destinationConnection.Open(); 

         using (var bulkCopy = new SqlBulkCopy(destinationConnection)) 
         { 


          bulkCopy.ColumnMappings.Add("name", "nameperson"); //THIS A MAPPING REPLACE IT WITH YOUR NEED 
          bulkCopy.ColumnMappings.Add("family", "family1"); 
          bulkCopy.DestinationTableName = "profile2"; 

          try 
          { 
           bulkCopy.WriteToServer(reader); 
          } 
          catch (Exception ex) 
          { 
           Console.WriteLine(ex.Message); 
          } 
          finally 
          { 
           reader.Close(); 
          } 
         } 
        } 
        MessageBox.Show("success"); 
       } 

      }

SqlBulkCopy的只做批量插入，所以任何現有的數據不應該被修改。

的MS Access> 2003，您需要使用Microsoft ACE，而不是JET
