`row_number`

  This is the desired row number of the new result pointer.

### 返回值

### 范例

Example #1 cubrid_data_seek() example

    <?php
    $conn = cubrid_connect("127.0.0.1", 33000, "demodb");

    $req = cubrid_execute($conn, "SELECT * FROM code");
    cubrid_data_seek($req, 0);

    $result = cubrid_fetch_row($req);
    var_dump($result);

    cubrid_data_seek($req, 2);
    $result = cubrid_fetch_row($req);
    var_dump($result);

    cubrid_data_seek($req, 4);
    $result = cubrid_fetch_row($req);
    var_dump($result);

    cubrid_close_request($req);
    cubrid_disconnect($conn);
    ?>

以上例程会输出：

    array(2) {
      [0]=>
      string(1) "X"
      [1]=>
      string(5) "Mixed"
    }
    array(2) {
      [0]=>
      string(1) "M"
      [1]=>
      string(3) "Man"
    }
    array(2) {
      [0]=>
      string(1) "S"
      [1]=>
      string(6) "Silver"
    }
