Query Error

[searls03]

Ok, i have been staring at this for hours and I can't seem to figure it out! this query keeps returning that the argument is not a valid mysql query result resource:

<?php
// Query member data from the database and ready it for display
$sql = mysql_query("SELECT * FROM categ where pares ='0'");
while($row = mysql_fetch_array($sql)){
$category = $row["categorys"];


?>

I have included a screen shot of what the database looks like. can anyone help me????? this is making me very mad.
