Datatables Server Side Search Danışma

Merhaba arkadaşlar.
122 bin ürün var sistemde datatable üzerinde gösterttim normal klasik datatable yaparsak vay halimize yüklenmez o sayfa fakat ben server side search olarak yaptım şuan sorun yok saniyeler içinde geliyor fakat şöyle birşey var acaba ben mi bilmiyorum?

Bende 2 tane tablo var bir ürünler diğeri iskontolar. iskontolar tablosundaki veriler sürekli değişiyor ürünlerdeki bilgiler değişmiyor fakat iskontoların hesaplanmış rakamları tutuluyor. Hesaplattıktan sonra ürünlerdeki alanlara yazdırmak zorunda kalıyorum hesaplatıp bunu tabikide yazdırmak zaman alıyor server side search'de 2 tabloyu bağlamak gibi birşey mümkün mü yoksa 1 tablodan mı veri çekiyor? Böylelikle hiç hesaplatıp diğer tabloya yazdırmadan iki tabloyu birleştirip direkt ekrana yazdırırım hesaplatıp.

Takip

Olayı tam anlamadım ama serverside da left join ile birleştirip 2 tabloyu göstermek mümkün.

İşte onu tam nerede ve nasıl yapacağımızı tam anlayamadım ben sadece orada tablo ve veritabanı adlarını giriyorum ayrıca primary key alanını belirliyorum bu kadar geri kalanında tablodaki hangi sütunda hangisi görüneceği belli oluyor tüm sorguyu vs kendisi yazıyor ben anlamadım

Mantığı şu şekilde hocam. Ama bu mantığın çalışması için alt taraftaki ssp.class.php yi kaydet.

// SQL server connection information
$SqlDetail = array(
'user' => $dbuser,
'pass' => $dbpass,
'db' => $dbname,
'host' => $server
);

$table = "table";

$joinQuery = "FROM {$table} AS a LEFT JOIN table2 AS b ON (a.deger=b.deger)";

$where = "Status='Active'";


$primaryKey = 'tableID';

echo json_encode(
SSP::simple( $_POST, $SqlDetail, $table, $primaryKey, $columns, $joinQuery, $where)
    );

            $sql_details['user'],
            $sql_details['pass'],
            array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION )
);
    }

kodla bağlamak yerine veritabanında bir view oluşturun, sorguyu oradan direk datatable a çekersiniz

Buna örnek verebilir misiniz?

şöyle ki mysql üzerinde view dediğimiz bir yapı mevcut joinli tablolar sanki tek tablo gibi davranabiliyor. böylelikle çağırırken vermiş olduğumuz isimle direk çağırıyoruz teknik anlatım kısmım çok iyi olmayabilir ancak mysql view diye araştırırsanız daha detaylı öğrenebilirsiniz. kod olarakta mysql de sql e kısmına create view

CREATE VIEW view_name AS
SELECT * FROM table_name left join table_name2 ;

şeklinde bir kullanımı var kodda da bunu normal tablo çağırır gibi select * from view_name olarak çağırabilirsiniz.
