PHP PDO如何運行多個查詢請求？

Question

你好，我想用PDOStatement執行在PHP這個SQL請求：

CREATE TEMPORARY TABLE r1 
SELECT CONCAT(MONTH(Heure_deb),'/',DAY(Heure_deb)) as 'Date', 
         Heure_deb, 
         Operateur.Id_op , 
         Nom_op , 
         Prenom_op, 
         Nom_act , 
         TIME(Heure_deb) as heure, 
         Commentaire, 
         Type 
         FROM Operateur, Pointage, Activite 
         WHERE Operateur.Id_op = Pointage.Id_op 
         AND Activite.Id_act = Pointage.Id_act 
         ORDER BY date, Id_op, heure 
; 
Create temporary table r2 
SELECT a.Id_op, a.Heure_deb, MIN(b.heure_deb) as fin, TIMEDIFF(b.Heure_deb, a.Heure_deb) as Time_Difference, ROUND(HOUR(TIMEDIFF(b.Heure_deb, a.Heure_deb)) + MINUTE(TIMEDIFF(b.Heure_deb, a.Heure_deb))/60,2) as Decimal_duree 
FROM Pointage a 
LEFT JOIN Pointage b ON a.Id_op = b.Id_op 
WHERE a.heure_deb < b.heure_deb 
Group by a.Id_op, a.Heure_deb 
; 
select CONCAT(MONTH(r1.Heure_deb),'/',DAY(r1.Heure_deb)) as 'Date', 
         TIME(r1.Heure_deb) as heure, 
         r1.Id_op , 
         Nom_op , 
         Prenom_op, 
         Nom_act , 
         Commentaire, 
         Type, 
         Time_Difference, 
         Decimal_duree 
from r1 
LEFT JOIN r2 ON r1.Id_op = r2.Id_op and r1.heure_deb = r2.heure_deb 
Order by Id_op, Date , heure 

這要求在phpMyAdmin Request

但在PHP返回這個取不工作，返回false但任何錯誤代碼。 PHP代碼：

$result=$objPdo->prepare($requete); 
    $result->execute(); 
    $err = $result->errorInfo(); 
    if(!empty($err[2])){ 
    echo"<script type='text/javascript'>alert('Erreur SQL :".$err[2]."');</script>"; 
    }else{ 
    while($row=$result->fetch()){ 
    echo"<tr> 
       <td>".$row['Date']."</td> 
       <td>".$row['heure']."</td> 
       <td>".$row['Nom_op']."</td> 
       <td>".$row['Prenom_op']."</td> 
       <td>".$row['Type']."</td> 
       <td>".$row['Time_Difference']."</td> 
       <td>".$row['Decimal_duree']."</td> 
       <td>".$row['Commentaire']."</td> 
      </tr>"; 
    } 
    echo"</table></div>"; 
}

有這個要求三個查詢，因此你必須在調用運行它們，而不是一個：

$objPdo->query("CREATE TEMPORARY TABLE r1 
SELECT CONCAT(MONTH(Heure_deb),'/',DAY(Heure_deb)) as 'Date', 
         Heure_deb, 
         Operateur.Id_op , 
         Nom_op , 
         Prenom_op, 
         Nom_act , 
         TIME(Heure_deb) as heure, 
         Commentaire, 
         Type 
         FROM Operateur, Pointage, Activite 
         WHERE Operateur.Id_op = Pointage.Id_op 
         AND Activite.Id_act = Pointage.Id_act 
         ORDER BY date, Id_op, heure 
;"; 

$objPdo->query("Create temporary table r2 
SELECT a.Id_op, a.Heure_deb, MIN(b.heure_deb) as fin, TIMEDIFF(b.Heure_deb, a.Heure_deb) as Time_Difference, ROUND(HOUR(TIMEDIFF(b.Heure_deb, a.Heure_deb)) + MINUTE(TIMEDIFF(b.Heure_deb, a.Heure_deb))/60,2) as Decimal_duree 
FROM Pointage a 
LEFT JOIN Pointage b ON a.Id_op = b.Id_op 
WHERE a.heure_deb < b.heure_deb 
Group by a.Id_op, a.Heure_deb 
;"; 

$result = $objPdo->query("select CONCAT(MONTH(r1.Heure_deb),'/',DAY(r1.Heure_deb)) as 'Date', 
         TIME(r1.Heure_deb) as heure, 
         r1.Id_op , 
         Nom_op , 
         Prenom_op, 
         Nom_act , 
         Commentaire, 
         Type, 
         Time_Difference, 
         Decimal_duree 
from r1 
LEFT JOIN r2 ON r1.Id_op = r2.Id_op and r1.heure_deb = r2.heure_deb 
Order by Id_op, Date , heure"; 

while($row=$result->fetch()){ 
    echo"<tr> 
      <td>".$row['Date']."</td> 
      <td>".$row['heure']."</td> 
      <td>".$row['Nom_op']."</td> 
      <td>".$row['Prenom_op']."</td> 
      <td>".$row['Type']."</td> 
      <td>".$row['Time_Difference']."</td> 
      <td>".$row['Decimal_duree']."</td> 
      <td>".$row['Commentaire']."</td> 
     </tr>"; 
} 
echo"</table></div>";
