Remarks

The MailChimpCommand class provides the following methods for executing commands against Mailchimp:

Item	Description
ExecuteReader	Executes commands that return rows.
ExecutePageReader	Returns a specific subset of rows when paging through the results of a query.
ExecuteNonQuery	Executes SQL commands such as INSERT, DELETE, UPDATE.
ExecuteScalar	Retrieves a single value (for example, an aggregate value) from a data source.

If execution of the command results in a fatal MailChimpException, the MailChimpConnection may close. However, the user can reopen the connection and continue.

This class supports cross-form data binding with the InterForm Technology.

Example

The following example uses the ExecuteReader method of MailChimpCommand, along with MailChimpDataReader and MailChimpConnection, to select rows from a table.

csharp

public void ReadMyData(string myConnString)
{
  string mySelectQuery = "SELECT Id, Name FROM Folders";
  MailChimpConnection mailchimpConnection = new MailChimpConnection(myConnString);
  MailChimpCommand mailchimpCommand = new MailChimpCommand(mySelectQuery,mailchimpConnection);
  mailchimpConnection.Open();
  MailChimpDataReader mailchimpReader = mailchimpCommand.ExecuteReader();
  try
  {
    while (mailchimpReader.Read())
    {
      Console.WriteLine(mailchimpReader.GetInt32(0).ToString() + ", " + mailchimpReader.GetString(1));
    }
  }
  finally
  {
  // always call Close when done reading.
  mailchimpReader.Close();
  // always call Close when done reading.
  mailchimpConnection.Close();
  }
}

Visual Basic

  Dim mySelectQuery As String = "SELECT Id, Name FROM Folders"
  Dim mailchimpConnection As New MailChimpConnection(myConnString)

    While mailchimpReader.Read()
      Console.WriteLine(mailchimpReader.GetInt32(0).ToString() + ", " _
        + mailchimpReader.GetString(1))
    End While
  Finally
      ' always call Close when done reading.
