Example

The following example creates a MySqlLoader, then populates Columns collection from table description, loads data, flushes the buffer and dispose internal MySqlLoader structures.

csharp

public void LoadData(MySqlConnection myConnection)
{
  myConnection.Open();
  myConnection.Database = "Test";
  MySqlLoader loader = new MySqlLoader();
  loader.Connection = myConnection;
  loader.TableName = "load_table";
  try
  {
    loader.CreateColumns();
    loader.Open();
    for (int i = 1; i <= 10000; i++)
    {
      loader.SetValue("id", i);
      loader.SetValue("char_field", "test string");
      loader.SetValue("date_field", DateTime.Now);
      loader.NextRow();
    }
    loader.Close();
  }
  finally
  {
    myConnection.Close();
  }
}

Visual Basic

Public Sub LoadData(ByVal myConnection As MySqlConnection)
  myConnection.Open()
  myConnection.Database = "Test"
  Dim loader As MySqlLoader
  loader = New MySqlLoader
  loader.Connection = myConnection
  loader.TableName = "load_table"
  Try
    loader.CreateColumns()
    loader.Open()
    Dim i As Integer
    For i = 1 To 10000
      loader.SetValue("id", i)
      loader.SetValue("char_field", "test string")
      loader.SetValue("date_field", DateTime.Now)
      loader.NextRow()
    Next i
    loader.Close()
  Finally
    myConnection.Close()
  End Try
