    OracleDataReader Class
    In This Topic
    Reads a forward-only stream of rows from Oracle.
    Syntax
    Remarks
    To create a OracleDataReader, you must call the ExecuteReader method of the OracleCommand object, rather than directly using a constructor.

    System.Data.Common.DbDataReader.IsClosed and RecordsAffected are the only properties that you can call after the OracleDataReader is closed. In some cases, you must call Close before you can call RecordsAffected.

    Example
    The following example creates a OracleConnection, a OracleCommand, and a OracleDataReader. The example reads through the data, writing it out to the console. Finally, the example closes the OracleDataReader, then the OracleConnection.
    public void ReadMyData(string myConnString)  {
            OracleConnection myConnection = new OracleConnection(myConnString);
            OracleCommand myCommand = (OracleCommand)myConnection.CreateCommand();
            myCommand.CommandText = "SELECT DeptNo, DName, Loc FROM Test.Dept";
            myConnection.Open();
            OracleDataReader myReader = myCommand.ExecuteReader();
            try {
                    // Always call Read before accessing data.
                    while (myReader.Read()) {
                    Console.WriteLine(myReader.GetInt32(0).ToString() + " " + 
                    myReader.GetString(1) + " " + myReader.GetString(2));
            }
            }
            finally {
                    // always call Close when done reading.
                    myReader.Close();
    
                    // Close the connection when done with it.
                    myConnection.Close();
            }
    }
    Public Sub ReadMyData(ByVal myConnString As String)
            Dim myConnection As New OracleConnection(myConnString)
            Dim myCommand As OracleCommand = myConnection.CreateCommand()
                    myCommand.CommandText = "SELECT DeptNo, DName, Loc FROM Test.Dept"
            myConnection.Open()
            Dim myReader As OracleDataReader = myCommand.ExecuteReader()
            Try
                    ' Always call Read before accessing data.
                    While myReader.Read()
                            Console.WriteLine(String.Concat(myReader.GetInt32(0).ToString(), " ", _
                            myReader.GetString(1), " ", myReader.GetString(2)))
                    End While
            Finally
                    ' always call Close when done reading.
                    myReader.Close()
    
                            ' Close the connection when done with it.
                            myConnection.Close()
            End Try
    End Sub
