Anzeigen aller Tabellenfeldwerte ohne While-Schleife in PHP

Question

Zeigen Sie alle Tabellenfeldwerte mit while Schleife an, aber der gleiche Wert wird mehrmals wiederholt.

Wie löst man es ... ?? Bitte jemand mir helfen?

$tender_select_query ="SELECT * FROM new_tender_one,new_tender_two,new_tender_three,new_tender_four WHERE new_tender_one.id = new_tender_two.tender_id AND new_tender_one.id = new_tender_three.tender_id AND new_tender_one.id = new_tender_four.tender_id"; 
$tender_select_result =mysql_query($tender_select_query); 
while($tender_row = mysql_fetch_assoc($tender_select_result)){ 
    $id =$tender_row['id']; 
    $work_name =$tender_row['work_name']; 
    $procuring_entity =$tender_row['procuring_entity']; 
    $reference_no =$tender_row['reference_no']; 
    $procurement_method =$tender_row['procurement_method']; 
    $bid_eligibility =$tender_row['bid_eligibility']; 
    $last_date =$tender_row['last_date']; 
    $pre_tend_info =$tender_row['pre_tend_info']; 
    $comp_work =$tender_row['comp_work']; 
    $tend_security =$tender_row['tend_security']; 
    $tend_instruction =$tender_row['tend_instruction']; 
    $tend_invite =$tender_row['tend_invite']; 
    $cont_details =$tender_row['cont_details']; 
    $publish_date =$tender_row['publish_date']; 
    $tender_status =$tender_row['tender_status']; 

    $tender_id =$tender_row['tender_id']; 
    $tender_type =$tender_row['tender_type']; 
    $tender_type_subcat =$tender_row['tender_type_subcat']; 

    $item_name =$tender_row['item_name']; 
    $item_description =$tender_row['item_description']; 
    $item_offer =$tender_row['item_offer']; 
    $quantity =$tender_row['quantity']; 
    $unit_type =$tender_row['unit_type']; 

    $required_name =$tender_row['required_name'];      

Answer 1

Das Problem der ist query Sie verwendet haben. Wenn Sie dieselbe tender_id in new_tender_one oder new_tender_two oder so weiter haben, erhalten Sie sicher mehrere Zeilen.

new_tender_one

id | tender_title 
1 | tender_1 
2 | tender_2 

new_tender_two

tender_id | tenderer_name 
    1  | smith 
    1  | john 
    2  | paul 

result

id | tender_title | tender_id | tenderer_name 
1 | tender_1  |  1  | smith 
1 | tender_1  |  1  | john 
2 | tender_2  |  2  | paul 

Stellen Sie sicher, dass sich tender_id s in den Tabellen new_tender_two, new_tender_three, new_tender_four nicht wiederholen.

Wenn ja, müssen Sie Unterabfragen verwenden. Dann müssen Sie wissen, welche record Sie von diesen anderen benötigen tables. (Bsp .: für id 1, ob smith oder john).
