Добрый день.
Для постраничного вывода данных из базы данных MSSQL Server 2008 использую код:

$entersql="SELECT TOP $num * FROM Price 
WHERE id_price NOT IN (SELECT TOP $numnext id_price FROM Price ORDER BY name) AND id_city='$id_city' AND id_group='$id_group' AND id_subgroup IN ('$id_subgroup') ORDER BY name";
$enterres = sqlsrv_query($conn, $entersql);

if( $enterres === false)
{
     echo "Error in query enterres preparation/execution.\n";
    // die( print_r(sqlsrv_errors(), true));
}
$t2='';
while($i = sqlsrv_fetch_array($enterres, SQLSRV_FETCH_ASSOC))
{

 if($inputby=='id_price'&&$typeby=='DESC'){$a--;}else{$a++;}

$id_price=($i['id_price']!='')? $i['id_price']:'0';

$name_city=$info_id_city['name']; 
 
$sql_id_producer_country = "SELECT name FROM Producer_country WHERE id_producer_country='$id_producer_country'";

Наименования фирм находятся в таблице Firm.
Мне нужно добавить сортировку по имени фирмы в запрос $entersql.

Подскажите возможно ли это и как это сделать?
