php - いくつかの基準によって分配される金額

Question

次の事実を考慮して、各エージェント手数料の値を分配したいと思います。

「n」個のコミッションを持つことができます
コミッションはエージェントクラスに割り当てられ、1 人のエージェントが複数のクラスに属することができます

assigned_commission テーブルの構造 (分配する必要があるコミッションを保存する場所):

commission_type | assigned_value | agent_class
energy_type_1   | 1500           | CLASS_1
energy_type_2   | 250            | CLASS_1
energy_type_3   | 750            | GENERAL_CLASS

agent_allocation の構造:

agent_code     | agent_class
AGENT_1    | CLASS_1
AGENT_2    | CLASS_1
AGENT_3    | CLASS_2
AGENT_1    | GENERAL_CLASS
AGENT_2    | GENERAL_CLASS
AGENT_3    | GENERAL_CLASS

ここに私が書いたコードがあります：

$stmt_assigned_commission  = $conn_bd->prepare('select * from assigned_commission ');                               
$stmt_comisioane_repartizate->execute(array());                             
$result_stmt_assigned_commission  = $stmt_assigned_commission ->fetchAll();                             
if ( count($result_stmt_assigned_commission ) ) {                               
    foreach($result_stmt_assigned_commission  as $row_assigned_commission ) {                           
        $commission_type[] = $row_assigned_commission ['commission_type'];              
        $assigned_value[]   = $row_assigned_commission ['assigned_value'];              
        $agent_class[]      = $row_assigned_commission ['agent_class'];             
    }                           
} else {                                
        $commission_type    = 0;                
        $assigned_value = 0;                
        $agent_class        = 0;                
}                               
$count_assigned_commission = count($commission_type);                               



$i = 0;                             
while ($i < $count_assigned_commission ) {                              

    $stmt_agent_distribution = $conn_bd->prepare('select agent_code from agent_allocation                           
    where agent_class = :agent_class');                         
    $stmt_agent_distribution->execute(array('agent_class' => $agent_class[$i]));                            
    $result_stmt_agent_distribution = $stmt_agent_distribution->fetchAll();                         
    if ( count($result_stmt_agent_distribution) ) {                         
        foreach($result_stmt_agent_distribution as $row_agent_distribution) {                       
            $agent_distribution[] = $row_agent_distribution['agent_code'];                  
        }                       
    } else {                            
            $agent_distribution = 0;                    
    }                           

    $count_agent_distribution = count($agent_distribution);                         

    $j = 0;                         
    while ($j < $count_agent_distribution) {                            
        $stmt_calculate->bindValue(':agent_code', $agent_distribution[$j]);                     
        $stmt_calculate->bindValue(':commission_type', $commission_type[$i]);                       
        $stmt_calculate->bindValue(':assigned_value', $assigned_value[$i]);                     
        $stmt_calculate->execute();                     
        $j++;                       
    }                           
    $i++;                           
}

結果：

agent_code | commission_type | assigned_value
AGENT_1    | energy_type_1   | 1500
AGENT_1    | energy_type_2   | 250
AGENT_1    | energy_type_2   | 250
AGENT_1    | energy_type_3   | 750
AGENT_1    | energy_type_3   | 750
AGENT_1    | energy_type_3   | 750
AGENT_2    | energy_type_1   | 1500
AGENT_2    | energy_type_2   | 250
AGENT_2    | energy_type_2   | 250
AGENT_2    | energy_type_3   | 750
AGENT_2    | energy_type_3   | 750
AGENT_2    | energy_type_3   | 750
AGENT_3    | energy_type_3   | 750

返すべきもの:

agent_code | commission_type | assigned_value
AGENT_1    | energy_type_1   | 1500
AGENT_1    | energy_type_2   | 250
AGENT_1    | energy_type_3   | 750
AGENT_2    | energy_type_1   | 1500
AGENT_2    | energy_type_2   | 250
AGENT_2    | energy_type_3   | 750
AGENT_3    | energy_type_3   | 750

ループ内でクエリを実行しているときはいつでも、MySQL JOIN で同じことを実行できます。

SELECT
    a.agent_code, c.commission_type, c.assigned_value
FROM
    agent_allocation a
JOIN
    assigned_commission c
ON
    a.agent_class = c.agent_class
ORDER BY 
    a.agent_code, c.commission_type

これで、コードを次のように縮小できます-

$stmt_assigned_commission = $conn_bd->prepare('SELECT a.agent_code, c.commission_type, c.assigned_value FROM agent_allocation a JOIN assigned_commission c ON a.agent_class = c.agent_class ORDER BY a.agent_code, c.commission_type');
$stmt_assigned_commission->execute();                             
$result_stmt_assigned_commission = $stmt_assigned_commission->fetchAll();                             
if (count($result_stmt_assigned_commission)) {                               
    foreach($result_stmt_assigned_commission  as $row) {                           
         echo $row['agent_code'];              
         echo $row['commission_type'];              
         echo $row['assigned_value'];             
    }                           
}
else{                                
//
}

ここで、重複が発生している理由を簡単に確認します。毎回、以前の値を置き換えずにwhile ($i < $count_assigned_commission )新しい値を追加しているため、基本的にこれを行っています-$agent_distribution[]

// 1st loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // New
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // New

// 2nd loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // From 1st Loop
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // From 1st Loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // New
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // New

// 3rd loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // From 1st Loop
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // From 1st Loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // From 2nd Loop
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // From 2nd Loop
$agent_distribution[] = array("agent_code"=>"AGENT_1");  // New
$agent_distribution[] = array("agent_code"=>"AGENT_2");  // New
$agent_distribution[] = array("agent_code"=>"AGENT_3");  // New

つまり、ファイナルwhile ($j < $count_agent_distribution)を行うときは、2 回 (1 回目while ($i < $count_assigned_commission )のループ)、4 回 (2 回目while ($i < $count_assigned_commission )のループ)、7 回 (3 回目のwhile ($i < $count_assigned_commission )ループ) を実行します。

だから結局こうなる―

$i = 0;                             
while ($i < $count_assigned_commission ) {    // 3 Times

$stmt_agent_distribution = 'select agent_code from agent_allocation where agent_class = '.$agent_class[0];
$result_stmt_agent_distribution[] = array("agent_code"=>"AGENT_1");
$result_stmt_agent_distribution[] = array("agent_code"=>"AGENT_2");

        $agent_distribution[] = $row_agent_distribution['agent_code'];                  
    }                       
}
$count_agent_distribution = count($agent_distribution); // 2 
$j = 0;

    $stmt_calculate->execute();
    $results[] = array("agent_code"=>"AGENT_1","commission_type"=>"energy_type_1","assigned_value"=>1500);

    // second time

$i++;

実際の修正

$agent_distributionしたがって、各ループで「新しい」を作成する必要があるため、変更します-

$agent_distribution[] = $row_agent_distribution['agent_code'];                  
... 
$count_agent_distribution = count($agent_distribution);
...                        
$stmt_calculate->bindValue(':agent_code', $agent_distribution[$j]);

に

$agent_distribution[$i][] = $row_agent_distribution['agent_code'];                  
... 
$count_agent_distribution = count($agent_distribution[$i]);
...                        
$stmt_calculate->bindValue(':agent_code', $agent_distribution[$i][$j]);

だから今は次のようになります

...
while ($i < $count_assigned_commission ) {                              

    $stmt_agent_distribution = $conn_bd->prepare('select agent_code from agent_allocation                           
    where agent_class = :agent_class');

今$agent_distributionはこのようになり、重複した結果が削除されます

// 1st loop
$agent_distribution[0][] = array("agent_code"=>"AGENT_1");
$agent_distribution[0][] = array("agent_code"=>"AGENT_2");

// 2nd loop  - does not have the rows from the 1st loop
$agent_distribution[1][] = array("agent_code"=>"AGENT_1");
$agent_distribution[1][] = array("agent_code"=>"AGENT_2");

// 3rd loop - does not have the rows from the 1st and 2nd loops
$agent_distribution[2][] = array("agent_code"=>"AGENT_1");
$agent_distribution[2][] = array("agent_code"=>"AGENT_2");
$agent_distribution[2][] = array("agent_code"=>"AGENT_3");

ループ内でループを実行すると、この種のエラーが発生しやすくなり、理由がわからずに結果がすぐに拡大するため、JOIN クエリを引き続きお勧めします。
