ERROR 0 No database selected что не так помогите пожалуйста

вот код :
<?php
require_once ('bd_conect.php'); //можно использовать include //
echo "ERROR ".mysql_errno()." ".mysql_error()."\n";
mysql_query ("SELECT * FROM `GPS_table`");
$q = mysql_query ("SELECT * FROM GPS_table");

?>

база данных выбрана?
mysql_select_db

_____________

ДА выбрана
$db_name = "dolgam";
$connect = mysql_connect("$host","$login","$pwd") OR DIE("Не могу создать соединение ");
mysql_select_db (`$db_name`,$connect);

Лежит в bd_conect.php

mysql_select_db (`$db_name`,$connect);

и

mysql_select_db ($db_name,$connect);

Найди 2 отличия )

_____________
Mysql, Postgresql, Redis, Memcached, Unit Testing, CI, Kohana, Yii, Phalcon, Zend Framework, Joomla, Open Cart, Ymaps, VK Api

 mysql_connect("$host","$login","$pwd")

и незачем обрамлять переменную, если она используется не в контексте конкатенации.

 mysql_connect($host,$login,$pwd)

_____________

mysql_select_db (`$db_name`,$connect);

mysql_select_db ($db_name,$connect);

Одну проблему решили но теперь ищё бадяга (((
