select inside a while loop

Hello,

I have two mysql tables songs and artists. They look like this:

CREATE TABLE `artists` (
  `artist_id` int(10) unsigned NOT NULL auto_increment,
  `artist_name` varchar(100) default NULL,
  `artist_img` varchar(50) default NULL,
  PRIMARY KEY  (`artist_id`),
  UNIQUE KEY `artist_name` (`artist_name`),
  KEY `artist_id` (`artist_id`)
) TYPE=MyISAM;

CREATE TABLE `songs` (
  `song_id` int(11) NOT NULL auto_increment,
  `song_title` tinytext,
  `artist_id` tinytext,
  PRIMARY KEY  (`song_id`)
) TYPE=MyISAM;

Currently I have the artist_id in the songs table setup has a text field with artist names in them temporarily. First I want to select all the artist_ids(with the names) and find the artist_id for that name in the artist table. Then update the artist_id in the song table with the artist_id in the artist table. Then convert the artist_id in the song table to int.

So with all that said here is what i have done that doesn't work,

$result = mysql_query("SELECT artist_id FROM songs",$db) or die(mysql_error());

  if ($row = mysql_fetch_row($result)){
      do {

$artist_name = $row["artist_id"];
$result_1 = mysql_query("SELECT artist_id,artist_name FROM
artists WHERE artist_name = '$artist_name'",$db);
$row_1 = mysql_fetch_array($result_1);
print "$row_1[artist_id]-$row_1[artist_name]";

	}while ($row = mysql_fetch_array($result));
  }	

I haven't even been able to get to the update part. I'm pretty sure the above fails because of the var $artist_name after the first run through.
Any help would be appreciated.


Thanks,
Mike
