note 110063 added to function.mysql-query

My query works fine, run the SQL in APPSERV, but throw me an error. "Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in" this is my code: $con = new conexion(); $link = $con->conectar(); $SQL = 'SELECT * FROM usuario INNER JOIN persona ON usuario.id_persona = persona.id WHERE usuario.tipo = "'.$tipo.'" AND usuario.contraseña = "'.$pass.'" AND usuario.nombreUsuario = "'.$user.'"'; $rs = mysql_query($SQL,$link); $row = mysql_fetch_array($rs);//end The incredible thing is that previously run a query and it worked fine.
