PHP PDO làm thế nào để chạy một yêu cầu nhiều truy vấn?

Có ba truy vấn trong yêu cầu này và do đó bạn phải chạy chúng trong ba cuộc gọi, không phải một cuộc gọi:

$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,

Order by Id_op, Date , heure";

while($row=$result->fetch()){
    echo"<tr>
