This is not true, the resource link identifier is optional! If unspecified,
the last opened link is used. My suggestion is to check the results of
mysql_error() for more information on the failed query.

$dbh = mysql_connect("localhost", "login", "password") or

mysql_select_db("database");
$query = 'SELECT * FROM cities';
$result = mysql_query($query);

echo ('<tr> <td class="city">' . $row[0] . ', ' .
$row[1] . '</td>

</tr>\n"); }
getting this error:
*Warning*: mysql_fetch_row(): supplied argument is not a valid MySQL
result resource in...
so... is the problem with the $query?
I don't see anything wrong (assuming my login and database selection is
correct)
what are the common errors here?

mysql_query needs both the query variable and the connection
variable....
mysql_query($query, $dbh);
HTH!
