    MagentoCommand Class
    In This Topic
    Represents a SQL statement or stored procedure to execute against Magento.
    Syntax
    Remarks
    The MagentoCommand class provides the following methods for executing commands against Magento:
    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 MagentoException, the MagentoConnection 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 MagentoCommand, along with MagentoDataReader and MagentoConnection, to select rows from a table.
    public void ReadMyData(string myConnString)
    {
      string mySelectQuery = "SELECT customer_id, lastname FROM Customers";
      MagentoConnection magentoConnection = new MagentoConnection(myConnString);
      MagentoCommand magentoCommand = new MagentoCommand(mySelectQuery,magentoConnection);
      magentoConnection.Open();
      MagentoDataReader magentoReader = magentoCommand.ExecuteReader();
      try
      {
        while (magentoReader.Read())
        {
          Console.WriteLine(magentoReader.GetInt32(0).ToString() + ", " + magentoReader.GetString(1));
        }
      }
      finally
      {
      // always call Close when done reading.
      magentoReader.Close();
      // always call Close when done reading.
      magentoConnection.Close();
      }
    }
    Public Sub ReadMyData(myConnString As String)
      Dim mySelectQuery As String = "SELECT customer_id, lastname FROM Customers"
      Dim magentoConnection As New MagentoConnection(myConnString)
      Dim magentoCommand As New MagentoCommand(mySelectQuery, magentoConnection)
      magentoConnection.Open()
      Dim magentoReader As MagentoDataReader = magentoCommand.ExecuteReader()
      Try
        While magentoReader.Read()
          Console.WriteLine(magentoReader.GetInt32(0).ToString() + ", " _
            + magentoReader.GetString(1))
        End While
      Finally
          ' always call Close when done reading.
          magentoReader.Close()
          ' always call Close when done with connection.
          magentoConnection.Close()
      End Try
    End Sub
