8.81.57 mysqli_multi_query()mysqli->multi_query()Exécute une requête MySQL multiple

[ Exemples avec mysqli_multi_query ]   PHP 5

Style procédural

bool  mysqli_multi_query ( mysqli   link , string   query )

Style orienté objet (méthode)

mysqli bool  multi_query ( string   query )

mysqli_multi_query exécute une ou plusieurs requêtes, rassemblées dans le paramètre query par des point-virgules.

Pour lire les résultats de la première requête, vous pouvez utiliser les fonctions mysqli_use_result et mysqli_store_result . Tous les autres résultats de requêtes peuvent être atteints avec mysqli_more_results et mysqli_next_result .

mysqli_multi_query retourne FALSE uniquement si la première requête échoue. Pour récupérer les sous-séquences d'erreurs issues des autres requêtes, vous devez appeler d'abord la fonction mysqli_next_result .

Style orienté objet

<?php
$mysqli
= new mysqli("localhost", "utilisateur", "mot_de_passe", "base");

/* Vérification de la connexion */
if (mysqli_connect_errno()) {
    
printf("Connexion échouée :  %s\n", mysqli_connect_error());
    exit();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Nom FROM Ville ORDER BY ID LIMIT 20, 5";

/* Exécution d'une requête multiple */
if ($mysqli->multi_query($query)) {
    do {
        
/* Stockage du premier résultat */
        
if ($result = $mysqli->store_result()) {
            while (
$row = $result->fetch_row()) {
                
printf("%s\n", $row[0]);
            }
            
$result->close();
        }
        
/* Affichage d'une séparation */
        
if ($mysqli->more_results()) {
            
printf("-----------------\n");
        }
    } while (
$mysqli->next_result());
}

/* Fermeture de la connexion */
$mysqli->close();
?>
Style procédural

<?php
$link
= mysqli_connect("localhost", "utilisateur", "mot_de_passe", "base");

/* Vérification de la connexion */
if (mysqli_connect_errno()) {
    
printf("Connexion échouée :  %s\n", mysqli_connect_error());
    exit();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Nom FROM Ville ORDER BY ID LIMIT 20, 5";

/* Exécution d'une requête multiple */
if (mysqli_multi_query($link, $query)) {
    do {
        
/* Stockage du premier résultat */
        
if ($result = mysqli_store_result($link)) {
            while (
$row = mysqli_fetch_row($result)) {
                
printf("%s\n", $row[0]);
            }
            
mysqli_free_result($result);
        }
        
/* Affichage d'une séparation */
        
if (mysqli_more_results($link)) {
            
printf("-----------------\n");
        }
    } while (
mysqli_next_result($link));
}

/* Fermeture de la connexion */
mysqli_close($link);
?>

L'exemple ci-dessus va afficher :
