$res=mysql_query("select * from table where id>10");

I can delete associated records using only $res ?

I mean i do not want make another query like delete * from table where id>10 so in this way $res can be used to get data, and then delete records.

note :: instead of clicking 'close' to close question, consider understand the question first, is a valid question and not was posted before. :genius:

You can't. The reason is that the resource you get is for the mysql_* PHP extension, and doesn't actually refer to data, a command, or anything on the server. They are completely separate. MySQL doesn't care or know how these things are implemented on the MySQL client.

You could take the associated records from your query, run a loop on them and delete as needed. Not sure if that helps with what you're trying to do?

<?
$res = mysql_query("SELECT * FROM table WHERE id>10"); 
$rescount = mysql_num_rows($res);
$resloop = 0;

while ($resloop < $rescount){

//do any additional logic here and then add delete statement if desired for the specific record

$resloop++;
}
?>
