Supplied argument is not a valid in MySQL result resource

Hi....
You need to check for errors after submitting a query and before you attempt to use the returned result identifier. The proper way to do this is with code similar to the following:
<?php

$result = mysql_query("SELECT * FROM tables_priv");
if (!$result) {
echo mysql_error();
exit;
}
?>
or
<?php

$result = mysql_query("SELECT * FROM tables_priv")
or die("Bad query: " . mysql_error());
?>
