mysql_data_seek和mysql_field_seek之间的区别？

Question

我发现他们都在做同样的工作。有没有区别？我想，我错过了一些东西。

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) 
?>
