mysql_data_seek与mysql_field_seek的差异？

Question

我发现他们俩的工作是一样的。有什么区别吗。我想，我漏掉了什么。

mysql_data_seek

<?php


    $sql="SELECT  * from testing";
    $result=mysql_query($sql);

    $row = mysql_fetch_object($result);
    echo $row->id . ' ' . $row->name; // Output is (1      Hassan)
    mysql_data_seek($result,2);
    $row = mysql_fetch_object($result);
    echo $row->id . ' ' . $row->name; // Output is (3      Rose)
    echo "<BR><BR>";
?>

mysql_field_seek

<?php 
mysql_connect("sql.server.com", "username", "password") or die(mysql_error()); 
mysql_select_db("database") or die(mysql_error()); 
$sql="SELECT  * from table1";
$result=mysql_query($sql);
$row = mysql_fetch_array($result);
echo $row['ID'] . ' ' . $row['Name']; // Output is (1      Hassan)
mysql_field_seek($result,2);
echo $row['ID'] . ' ' . $row['Name']; // Output is (3      Rose)
?>
