   ByVal value As Object _
)

Parameters

i: Zero-based index of the column.
value: Column value.

Remarks

Use SetValue(Int32,Object) method to set column with specific index in the current row to the value. To assign a column NULL value use Devart.Common.DbLoader.SetNull method instead.

The columns that you did not explicitly assign a value are considered to be NULL.

Example

This sample shows how to assign a value to a column referencing it by either name or index.

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(1, "test string");
      loader.SetValue("date_field", DateTime.Now);
      loader.NextRow();
    }
    loader.Close();
  }
  finally
  {
    myConnection.Close();
  }
}
