2. supplied argument is not a valid MySQL-link resource
snippet:
$result = mysql_query($sql, $db); // this is following an UPDATE
$row = mysql_fetch_assoc($result); // warning... 1.
if (mysql_affected_rows($result) !== -1) //warning...2.
print_r($result); // returns 1
another:
$sql = "DELETE FROM book_categories WHERE bookID = $bid";
$result = mysql_query($sql, $db); // warning...1.
$row = mysql_fetch_assoc($result); // warning...1.
if (mysql_num_rows($result) !== 0) {
